1080 is 2MP and cams are moving on. At the minute the DS-2CD2335 3MP Hik cam’s are the best all round cameras. Superior low light and great during the day. They have a slot for an SD-Card. If one of your cams are subject to bad weather, you can get a ‘hood’ attachment over the cam that shields the camera but tbh, the cams should be built so you don’t need it. Stick to Poe. So much easier for installation. One cat cable powers and sends data. There are new Hik EasyIP 4.0 cams out now. I am sorting out some to test. They will be my choice of cams if I like them. The new low light 8MP cam should be interesting. If you can hold out for a few weeks, they might be worth buying instead.
