Most owners start with a number in mind. The better starting point is a question: when something happens, what do you need to be able to see?
Camera count follows coverage. Cover the right places with the right image quality, and the number takes care of itself.
The five areas that matter most
- Entrances and exits — every door a person can walk through. The footage you’ll use most.
- Cash handling and points of sale — registers, safes, and the path between them.
- Loading docks, storage, and inventory — where shrinkage and disputes actually happen.
- Parking and perimeter — vehicles, walkways, and after-hours approaches.
- Interior blind spots — hallways, stairwells, and corners no one can see from a desk.
Typical starting points by building type
Every site is different, but after decades of walkthroughs, these are the common ranges:
- Small office or retail suite: 4–8 cameras.
- Restaurant or auto shop: 6–12 cameras.
- School or house of worship: 8–20 cameras.
- Warehouse or distribution center: 12–32+, depending on dock doors and racking.
- Multi-building or multi-site: scoped per building, tied into one viewable system.
Treat these as conversation starters, not quotes. A 4,000 sq ft site with good sightlines can need fewer cameras than a 2,000 sq ft site chopped into rooms.
What actually changes the number
- Layout — walls and aisles block sightlines; open floors don’t.
- Lighting — dark corners and backlit entrances often need a different camera.
- What you must identify — a face at a door needs more detail than a car in a lot.
- Retention and recording — more cameras means more storage for the same retention.
Why more isn’t automatically better
Every camera you add is one more feed to store, maintain, and actually look at. We’d rather design twelve cameras that cover what matters than sell you twenty that don’t.
That’s also why systems need upkeep after install day — a camera that quietly stopped recording covers nothing. Our Watch4U plans exist for exactly that.
How we scope it
We walk your site with you — entrances, registers, docks, blind spots — then map coverage and put it in a clear, itemized quote. You see every camera and what it’s for before anything is installed.
That walkthrough is free, whether you’re in Los Angeles, Burbank, Bakersfield, or anywhere else in our Southern California service area. See the kind of work we deliver on our recent projects page, or read more about our camera installation service.
