I will use Camera HD with Night Vision (wide angle) + IR for recording and mayby some Servo to follow object if camera won't be enough to embrace full room. USB HDD to put recorded video on him (i want to record in high quality so it will need more space). And Raspberry Pi with camera interface, would be nice to use Pi Zero but can't :(
Stand for camera i will print by my own and later i will link images and upload .stl files if someone will need.
I still need to learn a lot about Raspberry so it will be my first project and i hope i will make it! (Good thing is there's a lot materials for RPi to help me out! :) )
