Surveillance we've done (some, because it is about security)
Restaurant which is a staple of the community in a bad section of town had to make sure they were protected, so we installed tamperproof camera's to cover the parking lot.
In the office portion of a chain food store eyes are watching things.
Cameras positioned to watch the registers and the customers
Even when its dark, they can see you come up to the office.
Just some fished wiring for about 18 camera's (the white lines) in a pre-existing rack (not wired by us)
When one of our customers purchased a new building to set up shop in, we were hired to take care of the surveillance needs. This is what we did. Fished about 13 camera lines and got it all running so that they can access it through the web or a smart phone.
