Looking at a CCTV setup for UK home. To cover front side and back of house. Night vision. Record 24/7 and provide live feed when remotely viewing via app. MOTION detection option if possible that will alert with 20 seconds to minute recording before and after MOTION alert notification via app. POE OR alternate recommendation
You mention about POE, so what you would like to is IP system? Front side and back of house, so you are going to have at least 2 cameras? I would say you can go for a 4 cams CCTV kits. Price will be cheaper and all you need is inside. The functions you mention are quite basic, so you shouldn’t worry about that too much. Maybe you can have a look at this CCTV KITS and the Buying Checklist. Hope this is helpful to you.
