Superstore Surveillance - What Kind Of Cameras Should I Use?

I realize you are interested in 'live camera' design, but I have been involved in a number of 'big-box retail' projects that included a significant number of 'dummy minidome' housings (this one cost ~$10 USD but there are less expensive models) that cast the impression of many more cameras than actually deployed.

While the effectiveness of dummy cameras can be debated (almost half could not spot the fake in our shootout), many retailers use them. I may hang six housings in a merchandise areas, but have only have two live cameras between them. Since it is difficult to tell which housings are live and which ones are empty, the deterrence value for the price makes them a standard design element.

Yousef,

Does the store plan to have dedicated staff watching / controlling the speed dome cameras? If yes, that will make sense.

My first thought is to use minidome cameras at the cashiers as they will be less visible, unless for some reason you want customers to be aware of them, and then box cameras would accomplish that.
