Very good video, appreciated if you sketch a diagram for the whole circuit including camera and display connections

First time coming across your videos as soon as it hit 3:30 and you stated explaining you wanted people to understand the process I subbed! Great video! Thank you!

Thank you for the help mine was wired to just reverse lights and now with your diode info I was able to add a full on when driving switch and works great thanks for explaining so well appreciate the help

Excellent vid....this has answered the question I had. I knew some sort of isolator was involved but wasn't sure if it was a diode. I'm about to wire my reverse cam up to my stereo head unit. I also want to wire a separate switch in the dash to the cam and this has clarified it all for me. Thanks.

Great video. I always like it when people explain the ‘why’ so that it can be used in other setups. This was exactly what is was looking for.

Just found this video, paused it and liked it solely for the fact you just called out 95% of people on KZread 🤣. Everyone looks for a "how too video" not a "how it works video". Funny part about that is, that 95% of people will spend 95% more time on KZread. Because they will never actually learn anything, just learn how to "color in the lines".......Thank you

I have seen some of your wiring diagram video, I understand it now. Thanks.

I thought I had my setup ready to finish installatioin. Then sparks started to fly!!! Came here and now I understand Diodes! Thanks so much!!!

Thanks exactly what I need

Yes very helpful diode‘s are a great little things to use

I bought 6 diodes 2 of each 200 volts 400 volts and 500 volts my question is does da voltage matter even tho they are all 1 amp diodes?thanks for your time great videos.ps is there any tricks on installing 2 amps with out actually running 2 separate amp wire installation kits?that will b helpful if u have any information.

Awesome video that’s exactly what I want to do on my car. Can you use an eBay Toyota style switch with 4 wires? You mentioned that a switch with more than two legs won’t work? Why is that ? Than you in advance

Thank you sir!

Your actual backup light on the car probably draws much more current than the LEDs shown. You would need to measure the current going to the backup light to make sure you have enough current margin in the diode for that backup light circuit. Probably need 2 different current rating diodes or two higher current rating if using the same diode.

Excellent How to do Video...Thank You for your expertise....... KR

So nice of you, ty

good info. would it not have issues if both switch and reverse light is on?

So I was wondering why one would wire a 30/40 amp relay into the system? Seen one this way at the local parts yard but didn't get the time to trace it to maybe offset my curiosity. Thanks in advance for anything you can provide to this.

is there a easy way one could hook up mutiple cameras and be able to record and play footage through your head unit..if so do you know of a head unit that records footage?

Thanks very much, I test it on my car and work very well, now the switch power the backup camera without lighting up the reverse light.

If both switches are on? Florida (Sept. 17, 2020) - Yes, this was my question as well. What if both switches are engaged. That is, the car is put in reverse (sending power to the camera & monitor) and, the manual switch was on as well? I presume all that will happen is the backup lights will the be channeled power? The desired result should occur - that is, the backup light gets engaged on as the car is reversing, then , the backup light turns off when transition lever returns to drive. Yet, since the manual switch is on, the camera stays on. I suppose we should make sure the manual power switch has a plan to automatically turn off. Perhaps using ignition switch power. That way the camera, if left on by the manual switch, turns off when the ignition is turned off. How about this, just have the power to the camera and monitor turn on when the car turns on? Wait, the ford transit monitor is tied into the radio display, so if you have an always on trigger, you won’t see the radio menu screen? Tricky, but totally doable..

I have a 07 mdx that im installing a front cam,blindspot side mirror cams and a reverse cam and a multi camera interface. My question is how do I hook all the cams up so I can cycle through them anytime using a switch and does the type of switch matter???

I have some 10SQ050 10A 50V Schottky Rectifiers Diode lying around. I know it's an overkill but will it work with this setup or are there any dangers or backdrops if I use them in a similar setup?

Very good video, one suggestion that would help is to lay or the wires to show where they are all going. Looks like a rats nest cut off some of the excess wire for filming sake. Do you have a video showing the steps to set this system up from start??

This is very interesting. I was definitely prepared to do relay. I actually don't want to have a switch. I want it to be done automatically with the press of a button on the radio .. no, I just have to see what type of output the radio gives for the camera.. Has anyone made a backup camera that was able to be turned on automatically when accessing the video feed of the radio unit?

ok great , thx, also this is good to know if you are pulled over by cops to turn it on and keep it on, without them knowing the car is in reverse using the camera. now we need a microphone and a way to store broadcast and or take still shots w cameras in front and on the side of the car, maybe a roof mount 360 degree cam and micro phone.... or an app to take video, sound and still shots, to use later in court.... also is there a way to hook up a back up cam kit to the front of the car and link it to the installed screen in the car to do the same thing? if they have a back up cam for reverse , can we have a cam wired to "drive" and "in Park" mode to take pictures in the car using the in car video screen too. or is there way to make the back up cam take still photos? I want to drive down the road and see a great sunset or deer or accident or someone in trouble and take a pic video and sound, all vehicles should have this, without having to pull over, bc there's no room to stop or pull over.... any wisdom to this effect would be greatly appreacitated .... wire your vehicle for any situation without having to use your phone.. maybe a shutter button on the dash or in the steering wheel buttons....mahalo and alona

Awesome job brother it was super helpful and informative .

@Lesscoelectronics Could you make a video where you can manually switch between 3 modes "front-facing camera", "off" and "rear camera" ? The idea is to use a monitor/radio that only supports 1 video input but you can switch between 2 cameras (or multiple) and an off position where there is no video feed.

Thank you for the very informative video. I am planning to install 2cameras with switches in my panel van. Can I ask: is it not simpler to run a new 12V supply to the rear camera instead of using the reverse light as supply? I recall reading the reverse light should be avoided as a supply, but cannot recall the reason. Perhaps your video is aimed at those with a reverse camera system already installed and who want to add a switch?

@kentix417

Yes, you need two separate supplies of power to the camera for this. At heart it's a backup camera so you need power to it when you switch your car into reverse. The easiest way to get that power is to tap into the line that supplies power to the white backup lights because that line gets 12V only when you put the car into reverse and it's already in the trunk area of the car. There's plenty of extra power in that line to power a backup camera along with the lights because the backup camera is very, very low power. But to have the switch option, you need a completely separate incoming power line that bypasses the wire feeding the reverse lights. So you need to run a separate wire from your switch on your dashboard to the camera. Those two incoming power wires, the one tapped into the backup lights circuit (for when you shift to reverse) and the one coming from the switch on the dashboard (when you flip the switch) meet where the two diodes are and become one line. That one line then goes into the camera. So either line will power the camera. What the diodes do is prevent the power coming from either line from feeding into the other power line. The only place the current is allowed to go is through the camera, which is what you want.

could you also switch the earth through the diodes instead of the pos+ side to make it less 'arc happy' if you know what i mean? less crucial with the insulation behind a dash is what i was thinking.

the best ,thanks!

Hi there Trying to find a spilt monitor where I can use 4 cameras ?

Hey thank you for this video. I have a boss head unit which has a button to initialize the back camera however being that I’m tied into the reverse lights it tells me to check the cameras power source. Since I’m not in reverse the camera isn’t getting any power to it. Can you let me know HOW I CAN still have the camera activate in reverse but still be able to press a button and see the camera without being in reverse? Pretty much how can I provide reverse power AND CONSTANT POWER to manually check the camera when needed? Thanks

If I understand correctly you could power the camera through your toggle switch “ON” side. Sending power to the head unit for video feed while also powering the camera on. You may need to use a relay for this function.

I have two wires coming from my switch on with constant 12v (from radio 12v acc wire) and the second wire from switch tied into reverse cam trigger wire and reverse wire from twilight. I added 1amp 20v diodes and the switch triggers the radios reverse switch but the camera is not powering on.

I think this is an issue with a factory reverse camera. I’m trying to figure out the same thing. The cam in the video will be constantly on thus when you toggle video feed the camera is already on to send image. With our case, or mine at least, I have a 2021 Ram with a factory reverse camera. That camera has some sort of switch that is only sending power while the truck is in reverse. If I’m understanding all these concepts clearly. In this case you would have to route power from the on side of the switch you instal to the camera also so that when you call for video feed you’re also powering the camera on.

Any chance you have a wiring diagram for this? I understand the video, but not sure I know what everything was connected to. I have a sprinter van and I am going to install a aftermarket dbl din head unit with back up camera capability. I want the camera to come on when I flip a toggle switch and also when I put the van in reverse. I didn't realize I was going to have this problem with the reverse lights till I watched your video. I was really intrigued with the use of diodes. I've never used them before. Thanks.

Honest question. Why not run two relays. Both feeding the camera, one triggered from reverse voltage signal, one triggered from a switch signal. That way you aren’t throwing codes pulling amperage from the reverse light circuit in newer cars, the camera gets clean power from the battery, and no messing around with diodes?

How about if the power source says 12 volts on multi meter wired from a different location in your car. Do you use a higher diodes amp like a 12 volt one? I hope this question make sense.

@jacobm9697

Voltage and amperage are different. Ohms are resistance. (R) Amperage (I) is how hard power is being pushed (Current) Voltage is power or electricity (E) In short, Ohm’s Law. For instance to get amperage you could know that you have a 4 ohm subwoofer in a 12 volt system (any modern car electrical system). To calculate amperage Ohm’s Law would suggest to divide voltage by resistance to get amperage (E/R=I). Which would look like 12/4=3. So 3 amps is what a 4 ohm subwoofer would pull in a 12 volt system. You can change the formula for each figure. Voltage or Power = E Amperage = I Resistance or Ohm’s = R To get amperage as you see above is E/R=I To get voltage you would use IR=E To get resistance you would again divide but this time using E/I=R

Helpful! This idiot will follow instructions with my iPad but I also learned something too ;) thx 🙏

Nice video. I did something similar but didn't have the deck automatically switch when i manually toggled the switch. I have two camera inputs each with their own switch and on the deck i can switch between them. Question for you... why the extra diode to protect the switch? I can only see that for the case with led on the switch and to stop the led from coming on when in reverse. I only have a simple 2 prong switch and only use 1 diode to stop the reverse light from coming on when the switch is used.

If I understand correctly and you still care by now lol the extra diode was only for the built in LED in the rocker switch to only be on when the rear camera was in manual override. Without the extra diode the blue LED would be illuminated at all times on the rocker switch because of the constant back fed power.

can you describe the wires coming from the switch to the power and diode? are they positive and ground wires or are they both positive wires?

They’re both positive wires. The switch only needs to disrupt or complete the circuit.

I have a wireless backup camera monitor that is always on standby (dark) until it detects the camera wireless send signal, thus I need to install this on the backup camera circuit itself. The camera is hooked up to the reverse light. When car is put in R gear, reverse light lights up and thus camera gets power, monitor detects camera is ON and thus screen auto-activates to show camera image. If I want to turn the camera ON without putting car in reverse AND without running a switched +12v wire from the front, I am thinking of wiring up via diode to the license plate lights. If I want to turn camera on, I just turn on parking lights.... Do you foresee any problems with this setup?

I think you really only need 1 diode. You just want to block the current going to the backup light when the switch is on....you don't care if the current flow comes from the switch or the backup light when you are actually in reverse....so putting the diode from the backup light to the camera power input will prevent current going to the backup light when you flip the switch. When you put it in reverse the power will come from the backup light through the diode which will be forward biased....might as well use both diodes though since they are cheap.

Nice 👍
