Hello there,
I need a schematic for an ELP 2.0MP web cam.
I need to disable the IR LED's on the pc board.
Disconnecting the power connector to the LED board turns them off, but it also prevents the camera from switching into night mode. I need it to be able to switch to night mode.
The problem is that only one sensor is used to sense day or night, and it happens to be mounted on the LED board, so powering the board off also disables the night mode.
There is another thin wire that comes off the LED board but that wire is for the camera to sense the day or night modes, so pulling that connector out also disables the night mode.
There are 5 tiny transistor on the board, along with multiple SMD resistors and of course a lot of IR LEDs.
The LEDs can not be taped up or covered up because they generate heat. They have to have normal air flow.
I've considered a metal or plastic box to house the LED's in but then the sensor is not exposed in order to sense day or night. I may be able to make a pinhole so the sensor can get light, but i really dont want to have to go that route. If i had the schematic i would know what to do right away.
There is apparently no way to trace out the circuit because the board is a dark color and i think it is a multi layer pc board.
I also dont want to paint the LEDs because i may want to use them at a later date.
Any ideas?
