Some cameras mounted under Sofit on porch are had to cover with bag. I went 8 channels DVR with 2 Tb hard drive motion detection puts a marker so easy to find on playback. Don't forget you need a notice to state you have cctv. I posted a video on line of a gang of yobs jumping all over my front hedge, police contacted me for a copy of the footage and 3 of them got done as they had damaged other property up the street. £350 well spent
