A pharmacist friend called about a couple of after-hours
attempts to break into his establishment. In both incidents, the
perpetrators were frightened off by the intrusion alarm system.
Because he had a good shot of the criminals on video, he thought
the police would have little trouble identifying them, but he
was wrong.  When the police arrived on the scene and asked for a

to remove it from the digital video recorder (DVR). He realized
that there was no provision made to export digital images to a
magnetic or optical storage device. The only way to share images
with law enforcement using his DVR is to physically remove the
hard drive from the machine. In this case, the hard drive is
part of an assembly that can be pulled from a docking station
within the DVR using a key—a solution that unfortunately did not
simplify the process for the end-user.  Choosing a DVR begins
with a close examination of what the buyer intends to do with
