I built this to watch garden birds when nesting.

I have 2 triple nest boxes, fitted with cheap cctv cameras.
Cameras are 9vdc, with 6 I/R leds and audio, about £8.50 each.

The reciever is mounted close to the boxes, inside the garage, and the transmitter is in the bungalow.

The transmitter is controlled by Infra-red handset.(TVR010)
Cameras scroll through one at a time.
Speed of scroll is adjusted by the '-' & '+' buttons.
A piezo gives audio indication that I/R command has been received.

1-6 select camera to constantly display, power button resumes scrolling.

0 enters routine to disable/enable cameras, enter 1-6 then power button.
camera will be skipped when scrolling.

provision is made to attach a 20X4 oled, but I only used it for initial setup.

Audio is amplified by an LM386, refer to datasheet for further info.

U1,2,3 - CD4066

U4 - picaxe 20X2

U5 - LM386

IC1 - 78l05

C1 - 100uF 16v

C2,3,11 - 104

C4 - 10uF 16v

C5 - 47uF 25v

C13 - 100uF 25v

Q1,2,3,4,5,6 - BC547

R1,2,3,4,5,6,8 - 10K0

R7 - 22K0

R9,10,11,12,13,14 - 1K0

I'm interested in building a system for next year.

Cheapest I could see after a quick UK 'bay search
were much more expensive.

Where did you get your cameras?

make them an offer.

make sure the cameras you get have the clear I/R leds and not the black dummies.
I tried adding extra I/R leds in each box, but only slightly increased video level.
