Coverage area, camera type, and resolution all factor into the right camera count. Here's how we approach system design for our Northern Indiana clients.
The Most Common Question We Get
When a Northern Indiana business owner calls us for a security camera consultation, the first question is almost always the same: "How many cameras do we need?"
The honest answer is: it depends. But there's a systematic way to arrive at the right number — and it's not as complicated as some installers make it seem.
Start with Your Entry and Exit Points
Every exterior door, loading dock, emergency exit, and gate is a mandatory camera location. These are non-negotiable coverage points. A camera at each entry and exit point creates a perimeter ring — anyone who enters or leaves your property is on camera.
For a typical small business with a front door, back door, and side employee entrance, that's 3 cameras just for entry/exit coverage.
Add Parking Lot and Perimeter Coverage
The parking lot is often where incidents happen — vehicle break-ins, hit-and-runs, confrontations that start before anyone enters the building. A single wide-angle camera can cover a small lot (20–30 cars). Larger lots need multiple cameras, or PTZ (pan-tilt-zoom) units that can be remotely controlled.
Interior Coverage: Risk-Based Selection
Not every interior space needs a camera. Focus on:
- Cash handling areas — registers, safes, ATMs
- Server rooms and IT infrastructure
- Inventory and warehouse areas
- Common areas where customer/employee incidents could occur
For a 3,000 sq ft retail space, this typically adds 4–6 interior cameras to the exterior ring.
The Resulting Formula
| Building Type | Typical Camera Count |
|---|---|
| Small office (under 2,000 sq ft) | 4–8 cameras |
| Retail / restaurant | 8–16 cameras |
| Warehouse / light manufacturing | 12–32 cameras |
| Large commercial / campus | 32–100+ cameras |
Resolution Matters for Coverage Area
A 4K (8MP) camera can cover significantly more area than a 1080p camera while maintaining the resolution needed for facial and license plate recognition. This matters when you're deciding between one 4K wide-angle camera versus two 1080p cameras for the same space.
At NexGen, all new installations use 4K cameras as the standard — the marginal cost difference over 1080p is minimal, but the coverage and evidentiary value difference is substantial.
Don't Over-Camera — or Under-Camera
More cameras isn't always better. Every camera requires storage, a cable run, and a port on your NVR. We see installations where clients were sold 32 cameras for a building that needed 16 — wasting money and creating storage costs for footage that has no security value.
Conversely, we see buildings with obvious coverage gaps where the one camera that would have captured an incident wasn't there.
The Free Site Survey Approach
When NexGen conducts a free site survey for a Northern Indiana business, we walk the entire property with the owner or operations manager. We mark camera locations on a building diagram, specify the camera type for each location (fixed vs. PTZ, indoor vs. outdoor, focal length), and calculate storage requirements.
That proposal tells you exactly what you're getting and why — before you spend a dollar.
