Five-minute camera plan
List entry points
Every gate, main door and back door needs a camera — this is where faces are captured.
Add money and stock areas
Cash counter, store room, godown, office desk.
Add outside areas
Parking, the road in front, compound walls — one camera can cover a wide area.
Typical setups
Typical camera counts

FAQ
Questions people ask
Can one camera cover my whole shop?
Usually not well. A wide camera sees a lot but with less detail; faces at the entrance need their own camera.
Do I need a camera with a mic?
Audio helps at counters and entrances. Many of our kits include mic cameras.
How long is the recording kept?
It depends on the hard disk size, number of cameras and quality settings. Tell us how many days you want and we size the disk.
