How Many Cameras Does a Small Retail Store Need in Raleigh?
A small Raleigh retail store of about 1,200 square feet usually needs six to eight cameras: one on each exterior door, one over the register at face height, one covering the sales floor aisles, one on the stockroom door and one on the parking approach. Square footage matters less than the number of ways stock and people move in and out.
Counting cameras by floor area gives you the wrong answer. A 900 square foot boutique with one door and a wall of glass needs fewer cameras than a 900 square foot convenience store with a side entrance, a stockroom, a walk in cooler and a rear alley. Count openings and count transactions instead. That is where losses happen and where footage gets used.
What does a typical small store layout look like?
Here is how the positions usually stack up by store type. Ranges are what we specify in Cary and Raleigh units of similar size.
| Store type | Approximate size | Cameras | The extra positions |
|---|---|---|---|
| Boutique or gallery | Under 1,000 sq ft | 4 to 5 | Fitting room corridor entrance, window display |
| General retail | 1,000 to 1,800 sq ft | 6 to 8 | Aisle overview, stockroom door, rear exit |
| Convenience or bottle shop | 1,200 to 2,000 sq ft | 8 to 12 | Cooler, high value shelf, pump or lot view |
| Restaurant front of house | 1,500 to 2,500 sq ft | 8 to 10 | Bar, waiting area, service door, patio |
| Multi tenant unit with shared corridor | Any | Add 1 to 2 | Corridor and shared rear entrance |
Where does each camera go, and what is its job?
Give every camera one job. A camera with two jobs does neither well.
- Entrance, facing in at head height. This is the identification camera. Mount it around seven feet. A ceiling mount looking down gives you a hat brim. It should fill the frame with a face as someone walks through the door.
- Register, angled across the counter. It needs the customer’s face, the cash drawer and the hands. This camera resolves most disputes, and it is also the one that documents internal loss.
- Sales floor overview. One wide camera down the main aisle gives you context and a path to follow when you are tracking someone between other cameras.
- Stockroom or back of house door. Everything that leaves without being paid for passes a door like this one.
- Rear exit or delivery door. Fire exits that get propped open are a standing problem in strip units. This camera tells you when and by whom.
- Parking approach or storefront exterior. Set the lens narrow enough to read a plate at the distance vehicles actually stop. A wide lens covering the whole lot reads nothing.
For a store with high value small items, add a dedicated camera over that shelf or display case. For anywhere handling cash counts, put one over the office desk where the drawer is reconciled.
Where must a camera never point?
Two places, and getting this wrong is a serious matter rather than a style question.
Restrooms and fitting rooms are off limits. North Carolina law on secret peeping defines a room to include a restroom, bathroom, shower and dressing room, along with dressing stalls and similar areas designed to give privacy. A camera in or pointed into one of those spaces creates criminal exposure. Cover the corridor that leads to them and stop there.
The second is your neighbor’s private space. In a strip unit or a mixed use block, a camera angled so that it looks through a neighboring window or into a residential yard invites a complaint you do not need. Adjust the angle or use privacy masking in the recorder to block that part of the frame.
If your store handles card data in a way that brings you under PCI DSS, the standard has its own expectations about monitoring sensitive areas and keeping those records. Ask your payment processor what applies to your setup.
What resolution do you need to identify a face?
The useful measure is pixels across the subject rather than megapixels on the box. As a working rule:
- Identification, enough to recognize someone you do not know: aim for around 80 pixels per foot across the target.
- Recognition, enough to confirm someone you do know: about 40 pixels per foot.
- Detection, enough to know a person is there: about 20 pixels per foot.
A 4K camera on a 2.8mm wide lens spreads its pixels across a wide scene, so identification only holds close to the camera. The same camera on a longer lens holds identification much further out over a narrower view. This is why lens choice at the survey matters more than the camera model.
What about storage and who can watch it?
Eight 4K cameras recording on motion to a 4TB recorder will usually hold about 30 days. Continuous recording on the same setup gives you closer to 10. Most insurers and franchisors that specify anything ask for 30 days, so size the drive to that from the start.
Decide who can view live and who can export before the system is handed over. A manager who can pull a clip at 6am on a Sunday is the point of the whole exercise. Keep the admin account separate from the day to day account, and keep the admin password yourself.
A short pre-install checklist
- Walk the store at closing time and again at opening, because the light is different and so are the blind spots.
- Note every door, including the one that is always locked.
- Stand at the register and decide which way the identification camera has to face.
- Check where the recorder will live: a ventilated, lockable spot away from the front door.
- Confirm your internet upload speed if several people will view remotely at once.
Getting the layout right
Camera positions are worth an hour of somebody’s time before a single hole is drilled. We map them on your floor plan during a free survey and tell you plainly where a camera would be wasted. See the business CCTV page for how the survey runs, and our Cary page for the unit types we work in most often.
