My friend a qualified electrician can install CCTV so I want to buy a simple 2 camera set up, can anyone recommend one please. Would be nice to have good night vision, good quality image quality and we only need 7 days storage tbh though if 14 days not much more thats fine. Ideally be good to be able to watch it on an app on our phone or tablet. Presume we will need the box for recording the video to for storage. Budget wise not after anything flashy or expensive, any recommendations please?
