A common pattern plays out with business camera systems: an owner pays real money — sometimes $3,000 or more — for a setup that looks impressive on the surface. But when they actually need the cameras (an incident happens, insurance asks for footage, HR needs to review a dispute), things fall apart in ways they didn't anticipate.
This post is the guide we wish people had read before they bought. Bunn Communications installs commercial camera systems for North Carolina businesses — here's what actually matters, and where the cheap solutions cut corners that'll hurt you later.
Step one: what are you actually trying to accomplish?
"Security cameras" is not one thing. Before you buy anything, get honest about what you need them to do. The answer usually falls into one of three buckets:
- Deterrence — visible cameras so people know they're being watched. Reduces shoplifting, discourages employees from doing things they shouldn't, makes break-ins less likely.
- Evidence — clear recorded video you can hand to police, insurance, lawyers, or HR when something happens. This requires very different cameras and storage than deterrence.
- Operations — watching what's happening at your business when you're not there. Making sure employees are on time, customers are being helped, shipments arrive safely.
Most small businesses need a mix of all three, but the balance matters. A retail store mostly needs evidence-grade cameras at entry/exit and the register. A warehouse mostly needs operations cameras with wide coverage. A professional office mostly needs deterrence + evidence at the front door and parking lot.
If you can't articulate what you want the system to do beyond "see what's happening," you'll end up with a system that half-works at all three.
How many cameras do you actually need?
Most small businesses end up with 4-16 cameras. Here's how it typically breaks down:
| Business type | Typical cameras | Where they go |
|---|---|---|
| Small office (under 3,000 sq ft) | 4 – 6 cameras | Front entrance, back door, reception, one interior wide shot, one parking lot |
| Retail store | 6 – 10 cameras | Front door (in + out), register, aisles, back room, rear exit, parking |
| Restaurant | 8 – 12 cameras | Dining room, bar, kitchen entry, register, back door, walk-in, dumpster, parking |
| Auto shop / warehouse | 8 – 16 cameras | Each bay, parts counter, entry/exit, exterior yard, perimeter |
| Medical / professional office | 4 – 8 cameras | Entrance, waiting room, hallway, back exit, parking (no patient rooms) |
More cameras isn't always better. Once you pass about 16 cameras, the cost of reviewing footage, storage, and network complexity grows faster than the incremental benefit. A well-placed 6-camera setup beats a poorly-placed 12-camera setup every time.
NVR vs cloud: the most misunderstood decision
This is where most cheap systems go wrong. You've probably seen two kinds of camera systems advertised:
- NVR systems — Network Video Recorder. A small box at your business stores all the video on hard drives. You own the hardware and the footage.
- Cloud-only systems — cameras stream everything to the cloud, you pay a monthly subscription per camera to keep the footage accessible.
Cloud sounds simpler. It is not cheaper, and for most business use cases, it's worse. Here's why:
| NVR system | Cloud-only system | |
|---|---|---|
| Upfront cost (8 cameras) | $3,000 – $6,000 | $1,500 – $3,500 |
| Monthly cost | $0 – $20 (optional remote viewing) | $10-30 per camera = $80-240/month |
| 5-year total cost | ~$4,000 – $7,000 | ~$7,000 – $17,000 |
| Footage retention | 30-90 days standard, extendable | 7-30 days depending on plan |
| What happens if internet is down | Keeps recording to local drives | Stops recording (in most cases) |
| What happens if company goes out of business | Your hardware still works | You lose access to everything |
| Video quality | Whatever the cameras capture, full resolution | Often compressed for bandwidth before upload |
For most NC small businesses, NVR is the right answer. You pay more up front, nothing every month, footage lives at your business where you control it, and the system keeps working if your internet goes down. Cloud-only makes sense for a small shop with 2-3 cameras that genuinely wants zero hardware and doesn't mind the subscription — but past that, the math gets brutal.
A good middle ground is hybrid: NVR on site that records everything, with optional cloud backup of just the "important" clips (entries, motion events, alerts). You get the cost and reliability of NVR plus off-site backup of the clips that might be evidence.
Three mistakes we see most often on cheap installs
The $50 camera on Amazon specs out at "1080p HD." In reality, its lens, sensor, and low-light performance make its usable recognition range maybe 6-8 feet. So when someone breaks in at night, you'll have a grainy outline of a person in a hoodie — not a face. Commercial cameras from actual security brands use better sensors and lenses so you can identify faces at 15-25 feet even in low light. Cost difference per camera: $80-150. Worth every dollar when you actually need to identify someone.
Wi-Fi cameras are easier to install but much less reliable for business use. Interference from microwaves, other networks, and physical barriers causes dropouts — and the dropouts tend to happen exactly when you don't want them to. Business-grade systems use PoE (Power over Ethernet) — a single cable carries both data and power from an NVR or switch to each camera. Install takes longer, but the cameras basically never drop and they stay up during Wi-Fi problems. Always use wired PoE for commercial cameras unless there's a very specific reason not to.
The camera aimed from the back corner showing a wide overview of the parking lot looks great on a sales demo. When a car break-in happens, that footage shows two pixel-sized figures too small to identify. Cameras should be positioned to cover specific chokepoints — doorways, register areas, entry drives, cash drops — with enough zoom to actually see a face or license plate. This is where experienced installers earn their money: knowing where to put 8 cameras to cover 90% of real incidents, instead of 16 cameras that cover everything at low detail.
What a real commercial setup looks like
Here's what a properly specified system for a 6,000 sq ft small business (retail, professional, or office) looks like in 2026:
- Cameras: 8 total. A mix of dome cameras (indoor, recessed ceiling-mount) and turret cameras (outdoor, weatherproof). All 4K or 5MP resolution, with IR night vision to at least 80 feet, and H.265 encoding to keep storage requirements reasonable. Bunn installs CASE-brand commercial cameras on most jobs — a commercial security line we've used consistently for quality and build.
- NVR: 8-channel unit with 4TB of storage (stores ~30 days of continuous recording at the quality level above). Embedded operating system, no Windows update nonsense, very low failure rate.
- PoE switch: Ethernet switch with Power over Ethernet so a single cable runs each camera. Separated from your office network so camera traffic doesn't slow down business use.
- Cabling: Cat6 cable to every camera location, run through walls and ceilings rather than along surfaces. Connections made with proper compression connectors, not crimped or twisted.
- Remote viewing: Mobile app so you can check any camera from your phone. No subscription fee — the NVR handles the connection securely.
- Alerts: Smart motion detection that tells the difference between a person and a raccoon. Push notifications for specific events — door opened after hours, motion in restricted area.
- Documentation: Wiring diagram, camera location map, admin credentials, and a one-page "how to pull footage" guide left with you at install.
Installed cost for something like that: $4,500 – $7,000 all-in, depending on how many walls need wire runs and whether you need any outdoor conduit. No monthly fees. 5-year useful life minimum, often much longer.
Permits, privacy, and practical rules
A few things worth knowing before you install:
You can film your own business, with some limits
- NC is a one-party consent state for audio, but most commercial camera systems don't record audio by default (and shouldn't unless you have a specific reason).
- You can have video cameras wherever you have a legitimate business interest — entrances, workspaces, common areas, parking lots. Employees should be told cameras exist (usually a poster or employee handbook is enough).
- You CANNOT have cameras in restrooms, locker rooms, changing areas, or anywhere employees have a "reasonable expectation of privacy." This is a hard rule and a liability if violated.
- If you're in a shared building, confirm with your landlord before running cables through common walls. Most are fine with it but want to know.
You probably don't need a permit
Most NC jurisdictions don't require a permit for interior business camera installation. Exterior cameras that involve mounting to the building exterior may require a minor work permit in some cities — Raleigh is lenient, a few suburbs are stricter. A good installer will handle this for you.
Signs help, and aren't required
"This property is under video surveillance" signs aren't legally required for most NC businesses, but they help with deterrence and reduce any gray-area concerns about notice. We include them with most installs. $10 worth of signage, meaningful reduction in petty theft and vandalism.
How to tell if a quote you got is solid
If you've got a quote from another installer, look for these details. A real quote has them. A cheap one doesn't:
- Specific camera models listed — not just "8 HD cameras." You want the exact model numbers so you can look them up.
- Resolution and sensor size for each camera — 4K is better than 1080p, but a large sensor at 1080p can beat a small sensor at 4K. The spec sheet tells the story.
- NVR model, channel count, and storage size in TB — "500GB NVR" for 8 cameras means maybe 3 days of retention. Shop carefully.
- Cable runs and install approach — are they running inside walls, or stapling cable along the ceiling? The difference matters.
- Warranty terms — manufacturer warranty and installer warranty should both be listed.
- What happens when a camera breaks — how long, how much, truck roll cost.
- Training and documentation — how you'll actually use the system on day one.
If all you got was "8 cameras, $2,400," you don't have a quote. You have a guess.
