Powered doors driving me nuts help please :)

[Daffy]

Hello there

I installed a powered door at my base and did setup a inside camera and a outside camera and connected those to the door each camera will open the door with a 10 sec power on ... they work as they should do ... unless i connect both to the door when i connect the 2nd camera ( no matter what order i do it in ) only the last connected camera is wired to the door the other ( first wire ) gets cut off.

i know i have made it work before but not now ... any idea why this is ?

i got plenty of power for it as i got a 6 engine generator just to power this and nothing else.

Power goes : generator ( 6 engine ) to battery bank with 6 fully charged batteries

Cam 1 ( inside ): battery bank - cam 1 - door

Cam 2 : ( outside ) battery bank - cam 2 - door

only thing i can think off is that the door only allow 1 camera to be connected ? but that can't be right i hope

Help is very welcome please :)

Edit : it is a 3x3 steel garage door

All connections in powered objects can only go from Parent -> Child. You cannot connect a child connection back to any previous parent. More specifically each object may only recieve ONE parent connection, but can have any number of child connections. Attempting to wire a child to a parent will disconnect and replace the prior parent with the new connection, severing the power flow.

To try and demonstrate, let's say you have 5 relays in a circle, you connect them 1>2>3>4; At this point, you can connect 4 to 5; But not 5 to 4, because 4 already has a parent connection from 3; If you attempted to, it would remove the connection from 3->4 and replace it with the connection from 5, resulting in an outcome like this:
1>2>3 4<5

As well, For trigger objects like cameras and pressure plates, they have two different functioning modes when they're on the same line as another of it's kind.

If they're wired directly to eachother with no relay like this:
Power source->any stuff->Trigger 1->Trigger 2->whatever
They will function together to determine if any power gets down the line; Either one can enable power down the line- If you're familiar with logical circuits, this is an 'OR gate'.
Or (heh)
If you wire them separated by ANY other electrical object, like this:
Power source->any stuff->Trigger 1->any stuff->Trigger 2->whatever
They will function separately- Trigger 1 MUST be triggered for trigger 2 to even receive power; And both Trigger 1 AND Trigger 2 must be active for anything further beyond to receive power. Again, if you're familiar with logical circuits, this is a 'Sequential AND' gate; 1 must come before 2, and both are required.

Esoteric explanations aside, What you need to do is wire like this:
Power source->any relays/etc->Camera 1->Camera 2->Door; This makes the cameras function together and either one can open the door. Of course, this means that the two cameras must be placed in such a way that the wire can stretch from one to the other.

Hope this helps you figure it out.

That was so much help !

thank you
