As I’m due to tow horses for this years show season I thought it would be a good idea to have a camera in the trailer and monitor in the car so I can see how the horse is doing. I looked at off the shelf systems but they were all £100 plus and a lot weren’t wireless and required a constant power supply for the camera in the trailer. So it got me thinking that maybe I could knock something utilising my used pi zero’s. Project brief My idea is to use a pi zero enclosed in a monitor case and connected to it via it’s ‘TV’ pads and all powered via 5v. The camera end will again be a pi zero in some sort of enclosure running off a usb battery bank.
