Intelligent Car Video Switcher 3-way Input 1-way Output for the Car Camera

I purchased this so that I could install a front and rear video camera on my truck. The rear camera comes on when the truck is in reverse or I have switches to turn on either the front or rear camera manually. This item works as described and is very fuctional. My only complaint is the directions may be a bit unclear (think translated chinese) but they do suffice. One other bit of confusion is the manufacturers choice of RCA ends on this relay. Depending on your setup and where you mount his in relation to your head unit go ahead and buy a set of RCA double male & double female adapters. All in all it works just as described.

Unit arrived quickly. Instructions are for detectives. I've used a tester and labeled wires to assist future buyers who might not be as electrically able. I'll try to explain how this works. The yellow RCA connectors are permanently connected and require no trigger. So you remove your existing reverse camera connector from your head unit, (you'll need a female gender mender), and connect it to the male yellow connector that I labeled REVERSE. Then connect the female yellow connector to the head unit where you removed your reverse camera connector from (you'll need a male gender mender this time). They obviously placed these inverted. Now even without connecting any wires your reverse camera will work as normal. You can now connect 2 other cameras and run the corresponding trigger wires to a switch to supply 12 VDC to switch on as needed. The red trigger wire allows signal from red RCA input to go to head unit, and the purple does the same for the camera connected to the white RCA. Even if you have one of the cameras switched on, and select reverse gear, it will automatically give priority to the reverse camera through the yellow connector. Hope this helps. I took away 1 star for the inverted connectors and poor instructions.

I was looking to add a front view camera to my aftermarket stereo which only had one video input for the back up camera. Thanks to a detailed review from another purchaser I was able to easily set this up. It works great and I can access either the front or the rear camera at will. You will need to purchase some adapters due to the primary leads being inverted, but knowing that ahead of time made this installation a breeze!

Quit working after minimal use. Did work great. Can’t get any support to help with issue after wards which is also a fact to consider Will update with any resolution at a later date if issue is resolved with bad product

Works Good but, Instructions should be immediately trashed, Very poor instruction check other reviews for installation. I used in dash led lite switch for camera power. I managed to wire it correctley but not for elecrical challanged person.

Included instructions make great firestarter....(following them - only could ever get one (1) camera input to work)... Follow Peter Robinsons’ instructions in his review - you WILL need female and male RCA gender changers.... I had two 12V power plugs in my 2012 Silverado 2500 dashboard- I sacrificed one and added a 3-way switch to feed the “trigger” signal to switch to 2nd camera (or 3rd if I ever need one): I have a 2nd backup camera on a temporary mount with 15 foot / 5 m power & signal extension cable that I can plug in when needed: use it pointed directly at my 5th wheel hitch in bed of truck (standard backup cam is on rear license plate frame) Not sure if it’s because the “Video In” signals are not wired per manufacturer sheet - but the rear plate camera picture has noticeably more “static” now since installing the 3-way switcher - than when compared to when it was plugged directly into AV Receiver with backup screen I also found the RCA connectors seemed ‘loose’ when backup cameras were connected (one was not showing picture during testing): used black electrical tape to make sure connections don’t loosen up when everything is tucked into the dashboard....(From the ‘good old days’ of stereo components: the RCA cable connection cables on the back of receivers / tape decks / phonographs etc used to fit VERY snugly...not my experience here)

For my project, I am adding a side view Blind spot camera to my car. I already have a backup camera and radio that will display the video when I put the car in reverse. I wanted the side view camera to turn on automatically when I turned my right turn signal on, and then go off, once the turn signal goes off. To accomplish this, I had to add a few additional things to the video switcher. First off, the signal from the Turn signal was flashing/Intermittent. The signal needed to be a constant DC voltage so the camera would not turn on/off rapidly . I used a small digital timer that had a customizable delayed relay in it. That gave me the constant positive 12V signal I needed to tell the video switcher that the alternate side camera should be on. Now came the problem of telling the Radio to show what the camera is seeing Without putting the car in reverse. Since the radio only has one input for the reverse signal sensor, I added two Diodes to each of the signal wires. then wired them together into the radios reverse signal input. Now when I put it in reverse, the backup camera comes on, When I turn my right signal on, the side camera comes on. (The radio is tricked into thinking its the reverse camera again, the video switcher changes which camera it uses). Now, as for the product itself, It is wired incorrectly as everyone has stated. I popped it open and re soldered the correct female/male ends so I wouldn't have to waste money on gender switchers. It works better now! Hope the diagram helps!

I'm using this with a curb alert and rear-view camera. Both 1080P HD cameras and the quality of the video through this switcher are very good. Can't tell any noticeable difference. The unit I received has a different color code than the images shown in the product description. I found that the video connector and trigger wires come out of the case at the same spot. Not sure why they use different male/female connectors but it was easy to figure out which was video in/out and fire the trigger wires with +12v.
