Today we are going to cover part number 4843DAT from Master Lock. This is our hitch alignment and vehicle back up camera. This is a very simple system to install on your vehicle. It takes no time to install. First off we will cover the components of it. Starting back here. This is one of the mounts. This will actually mount the monitor to the windshield of your truck. It also has a neat little clip that goes into the vents on your vehicle if you want to mount it there temporarily. And this is the power supply cord and this plugs into your 12 volt power supply and plugs into the side of the camera. And on the back part, the actual camera itself is this unit right here. This actually will mount to the back of your vehicle on the trunk
And you can move the camera as you need it to put your hitch ball into view and you can back up your hitch ball to the trailer. It is powered by a 4-pole flat on your vehicle. So to power the camera on the back, all you have got to do is turn on your running lights. You plug it in, mount the camera, and you are ready to go. And then this little mount here. This actually fits onto the camera itself. What this part does is it actually guides the camera and keeps it center if you actually install it into your receiver hitch. You just push it in all the way. And then you can install your favorite hitch lock in place. And all you have got to do next is take your 4-pole flat and plug it into the wiring harness in the trailer. To start the install process is really easy. Let us go ahead with our rear camera that has a built in magnet so it sticks right to the truck.
Aim the camera right at the ball and then take your wiring harness with your adapter and just plug it into the 4-pole flat on your vehicle. Next we will go ahead and mount your monitor. You have got two different types of temporary mounting. One you have that sticks into the vent just like that and then your camera sits on top like that. We also have a windshield mount too. It is very sturdy and works really good. You can just go ahead and just put it on the inside of your windshield and push the lever down. And then you can install your camera. And really, all that remains, is go ahead and plug up the power cord. And then the power cord will go into the 12 volt power supply on your vehicle. Next we go through the functions on the camera. It actually has four different channels. And that is the control by the button on top. You push it. You will go through different channels and that is that takes care of that. The second button here on this model actually is not used at all. And then the last two buttons here , brightness and contrast. And it just cycles through until you get the combination that you like. Okay, we will go ahead and use this in typical application of backing up to a trailer. Then you can see how helpful it is to use. Turn on our running lights and our picture comes on our monitor and we just back up to our trailer. And then the adapter here has an extension for the 4-pole trailer. And just plug it right together. We have power for our lights and our trailer. Okay, and with that, that finishes our review with part number 4843DAT from Master Lock.

Rating is for the Master Lock camera. 5 STARS PLUS for eTrailer.com! Received it in 2 days with several emails letting me know the status! Better than Amazon Prime since this price was cheaper!. I like the backup camera. I have a 2005 Mercury Mountaineer that has no backup beeper, so wanted something to help with knowing what is behind me. Haven't tried it with my trailer yet. The camera worked first time and has a good picture. I don't use Bluetooth in that car, so I had no interference like others have had. As Julian M. said, the "flexible" mount with suction cup is good as long as you don't bend the 3/16" solid steel rod (what the heck???) that is within the plastic tubing. Trying to bend it close to the suction cup will break the suction cup plastic and render the mount useless (I thought I was being careful too!). The vent mount was also useless since adding the weight of the camera drops the camera so it's facing downward. Fortunately, I came up with a homebrew mounting and it worked (two-sided foam tape, plus scrap steel angle piece). When mounting the camera into the hitch receiver, the antenna hit the spare tire that's mounted under the vehicle, just forward of the receiver hole. Bending the antenna up slightly fixed the issue and I've put a locking pin to secure the camera for the winter. My final [non] issue is hooking up power to the camera. My Mountaineer has a 7 pin hitch circuit. I've added a 7 pin to 4 pin adapter for my trailer (and the camera). Unfortunately, It sticks way out the back now with the added camera connector. I need to find a 7 pin plug with wires out so I can connect to the backup lights (that is one of the circuits in the 7 pin connector). That way the camera will come on with the backup lights and I won't need to turn on my running lights. 106405

After an undisclosed family member ran over one of our kid's bikes for a third time (sorry dear), I began looking into reverse sensors and cameras. After much research I decided to try Master Lock's Wireless Camera (4843DAT) for the price, good reviews, and ease of installation. I'm not very handy, so ease of installation was key. Sensors all seemed to involve drilling holes into bumper unless you want to spend big money, and most cameras involved splicing reverse light wires into the camera wires. With this camera you simply put it in your trailer hitch and plug it in. I have to say this product was everything the description and good reviews claimed. Kudos to etrailer as well. Customer service and communication was excellent. Though I chose the free shipping (around a week I think), I received an email from etrailer the same day I ordered advising they were able to send out ahead of schedule. I received the product after only two days, and had it installed in about 10 minutes (no small feat for me). We have a 2007 GMC Yukon XL with a 7 prong connection. I did purchase a cheap 7 to 4 prong adapter for around $10 and a locking trailer hitch pin fro aroun $15 at an automotive supply store. I put camera (which has magnetic body) into trailer hitch, plugged it in, clipped monitor to air vent (or can use mounting arm) & plugged in to cigarette lighter and it worked! You can change channels and move antenna around for best picture. Used brightness and contrast to tweak picture. Works great, very wide, clear view even at night. Haven't ran into any interference yet. In a world where nothing seems to work as advertised, I was pleasantly surprised with this. Great value, especially for the price, very easy to install and use, and etrailer was awesome. Thanks. 106451

This is a good backup camera. It is susceptible to interference with color loss and screen flashing. I do understand that any bluetooth application will cause interference since it is in the same frequency band of 2.4 GHz. I do not have any bluetooth devices running at the time including my cellphone. I would say also that the flashing is intermittent and I cannot find any rhyme or reason to it. This camera is about 95% effective with the other 5% of the time jumping, flashing, or losing the color definition. For the price the camera seems to be a good buy in lieu of the 5%. It does make lining up my trailer hitch a breeze and I do use it on the end of the trailer for a rear facing view. When used in the receiver as a backup camera as described in the instructions is when most of the interference occurs. However, the manufacturer provided the specs, and special hardware to do just that. 122607

First of all, the package was delivered quickly and painlessly. I needed it in less than a week and I was not disappointed. The packaging had cracked during shipping (not etrailer's fault), so I called and quickly spoke to Tommy, so that if there was a problem, they would know that I received it this way. I was told that if I had any problems, to just let them know and they would take care of it. I got the system for my boyfriend, for his birthday because he goes fishing early in the morning, sometimes by himself and has to back his truck up without a second pair of "eyes." The night I gave it to him we hooked it up within a couple of minutes to "play" with it and see how it works (I think it took longer to get it out of the package than to hook it up:-)). We were so impressed with how easy it was to put together. No fuss whatsoever. We put the magnetic camera onto the tailgate, pointed it at the trailer ball and backed the truck up. On the screen, what you see is what you get. It was dark, and we could see clearly with the backup lights on. I was trying to think of one negative thing to say about this system or the company and I can't think of anything. Love it, love it, love it! Other systems that I have checked out require you to do a little bit of wiring. We would have had to possibly take it to someone to have this done (he doesn't do stuff like this), so the slightly higher price, I feel, takes care of any labor one would have to spend on having someone do it, and the ease, clarity and Master Lock name make it totally worth it. 59450

I am really enjoying this product. I can finally see what is behind me better!! The only issue I had holding this up from Excellent was I hooked it up to the suction cup mount, then when I tried to move it to the vent mount the little metal piece at the end of the suction cup mount came off with the unit. This happened right out of the box. I called customer service, who referred me to master lock, who said I had to return it as defective. I am debating whether to do this since I'm not planning on using the suction cup mount, so I might just glue it on myself, but the run-around was a little off-putting. 102576

Easy too setup, took about 5mins (no batteries needed). Tried it out and it works fine, just what you need when hooking ball hitch up to trailer single handed. Picture quality is as good as you need. Its made of plastic, lightweight but hopefully durable, only time will tell ! Thanks etrailer. 60570

This camera works great! I'm very, very Happy with it, nice clear Picture of my Trailer Hitch. Backed up to the Boat Hitch the very first time, no more getting in and out of the truck 10 to 15 Times to hook up the boat. I did have a problem at first, I figured it out, you need to have your lights on to get power to the camera plug, or you will not get a picture on the Screen. Happy Jack 140040

Bargain backup system Key points: -Installed in my 2010 Tundra Crew Max in less than 5 minutes. -You need to buy a locking hitch pin if you don't have one. -Point of reference missing when unit is installed inside the hitch receiver, so it's hard to tell how much distance there is behind you to an object. However, I have had enough practice now that the point of reference isn't really affecting my ability to gauge a proper distance to a vehicle or object behind me. -The suction cup application works very well, and is also very easy to install. -The A/C vent attachment only works when you remove the antennae, which means a little more static when using this option. -The 12V cord is kinda short. -Only 1 channel seems to work. -Very clean signal with very little flicker. However using any Bluetooth equipment near it will make picture useless. With all things considered, I am very pleased with this product, and I recommend it. It is affordable, reliable, and flexible. 3127

I was concerned about Wi-Fi interference from neighbors but the unit has worked flawlessly since my purchase. The mounting options for the display module are not the best but after some experimentation I found that it nestles nicely into the cup holder in my truck and gives a great image. The magnet on the camera is very strong and the camera does not move once you put it in place. The picture is clear and easy to see unless you are in deep shadow or after dark. The backup lights on my truck do not give enough light to see the ball and trailer on the display screen under these conditions. In those conditions you may need another source of light to allow you to see the hitch ball and trailer tongue. Overall I am very happy with the unit. So is my wife as prior to purchasing this unit she was my guide for alignment, a job she did not enjoy. I have already recommended this system to several people I know. 325612
Product had minor defect in a part which did not impede its performance. Product performs as advertised and is entirely sat- Isfactory for my needs. The service and follow up by customer service personnel has been excellent! I would recommend doing business with this organizati without reservation! 86086
by: Julian M.09/13/2013
I installed the camera to the tailgate magnetically and attached the wiring from the camera to my trailer lights wiring harness. All so good so far. I then was ready to locate to monitor. I attached the monitor to the flexible(????) mounting arm. The arm was so stiff that while holding the shaft and attempting to bend it into place for mounting, the suction cup base broke off. I did plug the monitor in and while holding the monitor and moving the antenna, I was able to get a display for a few seconds and then all it would do is roll the display. I was never able to get it to stop rolling no matter where the monitor was held or where the antenna was adjusted. I am somewhat amazed that with the reputation that Master Lock has that they would allow their name to be associated with such a piece of junk. I would not even recommend this to my worst enemy. 99795

I do not have a rating yet as my husband hasn't given it to me yet. I guess this is what came from UPS that he intercepted and wouldn't let me see. Thanks ever so much for telling me, the suspense was killing me and I hadn't been able to find the box. Lacy 61712
by: Tom B.05/13/2010
Highly Disappointing This cameras performance overall is highly disappointing. Display on monitor very poor due to excessive interference. Interference such as hash, snow, rolling and distortions except in areas where no other signals from any other radio signal sources are in the immediate area. While driving with camera installed into hitch receiver, the display on the monitor is all but useless. Display has way to much distortion, snow and hash to be of any value in my opinion. Very disappointed. For all but an occasional usage, this product may be of a benefit. The more expensive hard wired units will cost significantly more but may be worth the cost for those whom will use the camera often. Not a product I can nor will recommend to those whom can afford a hard wired device. 3027
by: Ryan P.07/16/2012
It may be a great camera for a smaller vehicle but I found that it does not work when inserted into the receiver tube of my 2012 F250.. The suction cup mount is too flimsy and difficult to mount due to its length. If you are looking for a camera for a smaller car with less transmission range then this may work for you. If you just place it on your tailgate, the magnet is not strong enough to hold it so expect it to be gone when you reach your destination. Save your money and buy a better camera, preferably one where the screen is part of the rearview mirror and the camera attaches to the license plate bracket. I'll keep the camera for grins and giggles but I will mount it in a different fashion to lessen the distance between the camera and the monitor. 48107

Got the camera in 3 days. Hooked it up per instructions and it was perfect,Great picture and very clear. First time I backed the truck up to hitch up, right on the money. Oh yes, no more yelling at my wife.Great product. 12700

I just got my Master Lock wireless backup camera and it only took 10 minutes to hook up. The first one I got and ended up taking back to the store wanted you to splice into the reverse lights of the vehicle. This one plugs right into the trailer light recepticle. It works so well that I even got my Dad one for his birthday. The display is crystal clear and the magnetic camera lets you place it anywhere you want. The only modification I'd make would be to make the camera cord connection a little longer. It's items such as this one that will be saving marrages the world round! 46883
by: Brian A04/28/2014
Bought the Master Lock instead of the Swift Hitch because of the larger screen size and, more importantly, the advertised use of a back up camera. The system works well on my F250 for hooking up to a trailer, but is useless as a back up camera when installed in the hitch receiver. The picture is jittery no matter which channel is used. Disappointing, but for the main use of hooking up to a trailer, it works very well. Not displeased, but if I had it to do over again, I think I would go with the Swift Hitch because of portability. 127877
by: Cliff. D10/06/2013
I love my Master Lock backup system. It has done away with the wife sreeming at me. When we are trying to back our trailer into spot and it also stopped my having to get out, to see what or how far the hitch is from the ball. The only thing I don't like is the window mount arm is to stiff to bend into possion. It needs to to be rediesigned. Other than that,the system has worked as advertised. Also I like the fact there are no batterys to replace.Grate product for the price. 102751
by: Mike J.05/29/2014
This product appears to provide the service described in the sales pitch. I have barely had a chance to use it, but on first use it did what was promised. I can see behind my truck which relieves my biggest worry of crashing into my boat trailer or my other cars in the driveway. There is only one drawback. The image on the monitor is not constant. The image flickers. I'm basically satisfied. We'll see what I have to say in a month. 133350

Master Lock Wireless Backup Camera The item is as described. It works well and is compact. I am replacing one of two other models l that were stolen. The power supply for the wireless camera on this model is what attrated me to this product. It is a great idea. No splicing in and it utilizes the existing tow plug-in. I am very satisfied with it. It is better than the PEAK and Vision stat that I previously owned. I recommed it. 4133
by: Lynn D.11/27/2012
Very nice product for the price. Easy to use and I like that it magnetically attaches to the tail gate for the short periods that I need it in place. I only use it to back up to my trailer then put it away, so I have not used any of the provided methods to mount the monitor, just lay it on my lap. In the future I may come up with something to mount it as the provided devices are not good for me. 60049
by: Works ok03/23/2014
The camera does work ok but does get glitchy with the picture,i used it to hitch trailer and it worked well enough to get the trailer lined up,i also installed a plugin inside my trailer so i could see what was happening inside the trailer while i was driving,was a little glitchy with the picture but it was inside a metal trailer but did show me the inside contents with 2 roof vents for light. 121828
by: Rob S.11/05/2013
Love the plug and use feature of this product. Plugged in and powered up the camera and backed within a inch of the trailer the first time I used it. Can now hookup the trailer without getting out numerous times to see where I am or need help from another person. Wish the monitor was bigger but with a little white paint on the hitch to make it stand out will make the process even easier. 106413
by: Lou K06/07/2015
Camera works when car is parked in my garage but as soon as I back it out into the driveway / drive around, picture disappears. Doesn't matter if the camera is magnetically attached to the trunk or in the hitch, it does not work. Tried all four channels, one works only in the garage, the other three don't work at all. So for me the product is useless and will be looking to return it. 201395
The camera works well Setup was easy and the field of view is very very good. I did have a little flickering interference with the screen in an industrial area, but the picture is clear at home. Aiming the camera is very easy-you can back right up to hitch up without getting out of the car now. Powering the camera from the flat plug was a great idea. 2866
by: Steve Martin06/28/2015
I think this could be a really nice unit. However, I couldn't get it to work. I verified every thing possible. I believe the display or ?? to be faulty. I'm now in the process of returning and was told they have to contact the manufacture to see how they want to handle the return. I'm not really happy with the overall experience as you can imagine. 207942
by: Frank Bai-Roossi,Roberta H09/15/2012
This is working just great. May have saved our marriage.......lol. Lexis was great help when I was looking for this. I do all the towing of the camper and backing up, Frank as no idea what to do. Thank you very very much for all your help. It's nice to have a company that hires knowledgeable people to help their costume. Roberta L Hamilton 54790
by: Lee L.10/15/2013
Don't have to have wife out there to help me back truck to camper. She likes that too. To bad we have to turn lights on though Wish the wip was longer so I could put the camera on back of camper when backing into a camper spot. I would recommened the Master Lock Wireless back up camera and alignment system-4843DAT. It is worth the price you pay. 103872
by: Shaun B.02/09/2017
Great product. Easy to use. Camera has good visibility. We have a debris blower that slides in the back of a truck for cleaning streets. We use the camera so the driver can see where it is pointing and how it's working. We use an old large camera case to store it when not using it. would recommend it to anyone looking for an easy to use system. 340308
by: Dale B.03/06/2012
Super easy to install, took about 3 minutes without even reading the instructions. Product was described perfectly by etrailer.com. and received it within a few days of ordering it online. Does exactly what I needed it for on my old truck for hooking up to my trailer, plus a back up camera as well. Thank you for your excellent service. 33156
by: Allan J.04/16/2012
The portable remote backup camera worked just as advertised. The instructions were easy to follow and the unit worked perfectly. My wife was really excited to see how well it worked because she will no longer have to direct me when backing up to hitch our trailer. The unit, price and service are everything you advertise! Thank you. 37449
Very easy to install and works well. The cable for the camera is a little short but not difficult to deal with. If its not long enough, go by a short cheap extension and all is well. The video quality is not as good as the backup cameras that are hard wired but I've not had any problem with snow and have had very little static. 34519
by: Bob B11/05/2014
I have experienced the same problems with this wireless unit as others have mentioned. The screen has static and then clears up for a very short time and then goes back to static. this situation is probably due to the bluetooth frequency. I'll put up with it for a while but I will definitely go to a hard wired unit in the spring. 159440
product is good and easy to install. however, i have a vehicle with navagation and bluetooth. when the bluetooth is searching it causes extreme noise (electrical intereference) making the backup camera useless. i cannot turn off bluetooth so i cannot use camera. without the bluetooth problem the unit is very good as advertised. 21280
HITCHUP SOLO IT TOOK ME LONGER TO CUT OPEN THE PACKAGING AND READ THE DIRECTIONS THAN TO MOUNT AND POWERUP THE CAMERA AND THE VIEW SCREEN. I MOUNTEDTHE SCREEN UPSIDE DOWN ON THE WINDSHIELD, BECAUSE I MOUNTED THE CAMERA UPSIDE DOWN, ON THE UNDERSIDE OF THE BALL, USING THE MAGNET. WORKS AS IF I HAD EYES IN THE BACK OF MY HEAD. 4002
Installs easily. Works pretty good. It does catch some interference but not enough to cause me to not like it. I just move the antennae a little and it usually cures it. You have to turn on your running lights to activate the camera on my vehicle--but I would not want it on all the time anyhow. I would buy it again. 92262
by: Michael aka CaptainMadMike08/27/2011
Easier to work then expected Hooked it up in about 1 minute Backed up and had trailer hooked up to truck without getting out of the truck absolutely no problem Can not believe did not buy this 15 years ago My only suggestion would be to have a 5 pin adaptor pass through to allow for the brake solenoid wire 22910
by: Steve T08/06/2012
Didn't work on my Toyota 4Runner. Picture would display for a second or two and then become scrambled for several seconds. Called support and they said the blue tooth on the vehicle interferred with the wireless picture transmission, and this is a common problem on cars with blue tooth. Had to return it. 50697
I never write reviews but this was truly a great experience. Order, ship, open, install.... that easy, and the camera is more than I expected and truly plug and play. Makes me wonder why I spent so much time researching products that needed to be installed professionally. Thanks, etrailer. 25531
by: Melvin L.04/05/2012
I can not believe how great this works when hooking up trailers. It is so easy and fast to align the hitch with the trailer. In the monitor, it looked perfect and when I got out and walked to the back of the truck....all I had to do was let the trailer down and hook up the safety chains. 36237
by: Wallace b08/04/2014
Great idea but noise when my engine is running makes the image almost unreadable. A little filter should fix this problem. For what it is designed for its a excellent product . I would buy another. I use it to hook up a goose neck trailer being able to move it easily is a perk. 144203
by: Dick W.08/27/2013
Camera does exactly what I needed it to do. It is simple to set up and to operate. It unplugs and stows in the glove box until I need it. System powers up from the vehicle so there are no batteries to mess with. No more back up direction required from my wife! 97169
by: Jill M08/03/2011
Great service on getting order to me was here in 2 days not standard 5. Hooked it up everything works great. Did not think about running lights needing to be on but Customer service call manufacturer for me and troubleshot my problem within 10 min. thanks 20989
by: Cathy Conley02/19/2011
Product was exactly as advertised. Order was painless and delivery was quick. Had tried to order product from another online company, but cancelled because never received. Was very satisfied with Etrailer's website and prompt delivery. 7468
etrailer is an excellent organization. Their customer service is excellent! The backup camera works extremely well, the only wish is that the monitor had an integrated battery, However I am pleased with the ease of use and performance. 111370
Product installs easily. Returned... or in process of doing so. Display had a great deal of interference... on all channels. Not sure why. I had this product on an 05 Pilot. It had some of the same,but, nowhere near that on this unit. 96770
by: Melvin B.02/24/2015
It's great. Very easy to set up and very easy to use. Worked perfectly for aligning my camper up to the hitch. No more pull up, get out, back up, etc. Delivery was quick. The whole process from stay to finish was excellent 175825
by: Chris L.09/19/2012
this product is great! Easy to install, good quality, and even better price.Customer service from eTrailer.com was the best I have ever dealt with. Great communication, updates on my order, and very quick shipping. 55113
by: E Jones05/01/2012
Received promptly and performed as discribed. Really believe it will keep me out of divorce court when trying to contect to and backing our travel trailer. Will defintely order again from etrailer.com.. 39021
by: PETE R.11/07/2016
TOOK ABOUT 10 MINUTES TO UNPACKAGE AND INSTALL. SEEMED TO WORK FINE ON INITIAL TEST. HAVEN'T HAD TIME TO TRY HITCH HOOK-UP YET BUT LOOKS LIKE WILL WORK OK. EARLY IN MY POSSESSION BUT SEEMS TO WORK OK. 314501
