Start with coverage goals
Count views, not buildings. A front entrance, loading area, cash register, parking approach, and rear exit are separate evidence goals even when one camera can see more than one area.
Build a camera schedule
- List every entrance and exit.
- Mark transaction, inventory, vehicle, and people-identification areas.
- Separate overview views from identification views.
- Add future channels before choosing recorder size.
A useful first estimate
Small homes often begin with four to eight views. Small businesses commonly need eight to sixteen. Warehouses and multi-building properties should be counted by entrances, aisles, docks, yards, and critical rooms rather than square footage alone.
Turn a floor plan into a camera schedule
Sketch the building, entrances and cable routes before shopping. Give each proposed view a name, such as front-door identification, driveway overview or stockroom aisle. Record the target distance, approximate scene width, available light and mounting surface. Two views of one entrance may solve different problems: a wide camera explains what happened, while a tighter view may preserve more useful detail.
For example, a home plan might include the front approach, driveway, rear door and two side paths. That is five distinct views, not an automatic recommendation for a five-camera package. Walk those positions during daylight and after dark; a garage corner or vegetation may create a sixth view that the sketch missed.
Check the plan before buying
A camera count is a starting design decision, not a guarantee of identification. Test the installed image and recorded playback with a person walking through each important view. Adjust placement or lens settings while safe access is available.
- Mark each view as essential now, useful later or unnecessary overlap.
- Check whether the proposed lens can frame the target at the actual distance.
- Choose recorder channels for the final planned count, not just the first order.
- Include mounts, weather-protected connections, cable, storage and power in the equipment list.
- Aim at your own property and consider privacy before recording neighboring areas or audio.
Frequently asked questions
Can one wide-angle camera cover an entire property?
It may provide an overview, but targets farther away occupy fewer pixels. Use separate views when entrances, faces or activity need closer detail.
Should I buy spare recorder channels?
Allow for realistic future views, then verify the recorder's bandwidth, storage and power capacity as well as its channel count.
