CCTV in a cafe or restaurant: where to put cameras

In a venue cameras do three jobs: order in the dining room, order at the till and order in the kitchen and storeroom. Each needs its own point.

Site survey and cost estimate are free of charge

Zones

Six points

EntranceEveryone who comes in and goes out is visible. The camera is placed so that a face can be made out.
TillA camera from above: the cashier's hands, the money and the guest are visible. This is the most disputed zone, so the view here should be close-up.
Dining roomAn overview of the tables: what happened and who was serving.
KitchenYou see how food is prepared and how order is kept.
Storeroom and cold roomsYou see who took produce and when.
Staff entranceDeliveries arrive and staff leave through it. A camera here is often needed more than in the dining room.

Questions

Where to start on a small budget?

With the entrance and the till. Other cameras are added later if the recorder was chosen with spare channels.

Can I watch the venue from a phone?

Yes. The owner sees live view and the archive from anywhere there is internet.

Who will work out how many cameras my venue needs?

We do: we visit, look at the layout and work it out. The visit and the estimate are free.
