Friend accused of stealing, video surveillance question!?

If there is no on-site monitoring the cameras will be recorded, no normal premises can afford anyone to stare at a monitor all day. Recording can be local in the building, or remotely at the installer's control centre. Alternatively the local recordings can be downloaded to control at intervals so there are multiple copies. ALL local dvr machines not only record, but present an Internet connection for remote recording. And it might be the security company have a contract only requiring them to attend on site within 3 or 4 days. in which case he might have to wait for that before they burn the dvd for the police. On all my systems I generally do this remotely.
