Camera count is the first question almost everyone asks and close to the last one that should be answered. It is an outcome of coverage decisions rather than an input to them, and a quote that leads with a number has usually skipped the thinking.
Start from the building’s choke points
Every building has places everyone has to pass through. The main entrance. The corridor to the back of house. The gate. The stairwell between floors. A camera on a choke point produces usable identification because people are funnelled into a predictable path at a predictable distance.
A camera covering a wide open area produces a record that something happened, which is a different and much less useful thing. Cover the choke points properly first. Most properties need fewer of these than expected, and they do the majority of the work.
Then the places you have actually lost something
This is the question that reorders the list, and it is the one a package quote cannot ask. Stock rooms. The yard. A particular door. The dumpster nobody watches. Where there is history there is usually a next time, and those positions justify themselves.
Then the approach
Knowing which direction someone arrived from and left in is frequently what turns footage into something police can act on. That is usually one or two cameras covering the approach to the property, not a ring of them around the perimeter.
Why more cameras can mean worse coverage
Budgets are finite, and this is the trade nobody explains. A fixed budget spread across twelve positions buys twelve compromised cameras. The same budget across seven buys seven that actually resolve faces and plates where it matters.
More cameras placed evenly around a building is the approach that produces the most footage and the least evidence. It looks thorough on a quote and disappoints in an incident.
The multiplier people forget
Every camera is not just a camera. It is a cable run, a switch port, a share of the PoE budget, and a share of the recorder’s storage. Adding four cameras to a design can push the switch, the recorder or the retention target into a different bracket. This is why camera count should be settled before hardware is specified rather than after.
Rough camera counts, not rules
A small retail unit is often well served by coverage of the entrance, the cash register, the back door and the stock room. A warehouse is usually driven by dock doors and the yard rather than by floor area, which is why square footage is a poor guide. A multi-tenant building is driven by the number of shared entries and common areas rather than by the number of tenants.
In every case the honest answer comes from walking the building, and any number offered before that is a sales figure rather than a design.
What should be on the camera quote
A count, and one sentence per position explaining what it is for. If a camera on the list cannot be justified in a sentence, ask what it is doing there. A good installer will tell you when something on their own list is not worth your money, and that is the answer worth hearing.
Camera count is an output, not an input. It falls out of the walk-through, which is the part Elite Security does before quoting. The blog covers more of the same, and commercial CCTV is the place to start for a number specific to your building.
