Came up with two possible designs:

1) Raspberry Pi approach:

+ can connect to any WebCam (or any additional tools if necessary) via USB
+ can be connected straight to a monitor for analysis later
+ would not consume too much battery power
+ can be programmed to stand by (save energy) when there is no action, and woken up again to take the picture
+ easier to reproduce and build yourself

+ can program anything on Linux

- difficult to get Raspberry Pi Zero
- would take time to program on Linux

2) KeyChain Camera approach:


+ cheap parts

+ easier to get the parts

+ there are also better KeyChains with PIR included etc. – but more expensive

+ easier to program

+ uses less battery life


- would need to install a bigger battery

- requires soldering

- photo resolution not so great
