Hello hope you can help! I've recently noticed a windows been smashed at the back of my work garage. Tried to have a look on the cctv and nothing has been recorded! Every window on the cctv has a F marked in the bottom left? At my other garage all are recording with a R and you can view everything needed. I'm a bit worried now as i need this sorted incase a break in happens! Any ideas on what i can do? The system is a sannce with 4 cameras in use. Many thanks adam.
