CCTV for Small Businesses: What You Actually Need

CCTV vendors love selling 16-channel or 32-channel systems to businesses that need 4-8 cameras. You end up with unused channels, overkill storage, and a complicated system nobody checks.

Here's what a practical CCTV setup actually looks like for a small business.

How many cameras do you need?

For a typical shop or small office, think about coverage points:

• Entrance/exit (who comes and goes)
• Till/counter area (transaction disputes)
• Stock room or back office (internal theft is real)
• Parking area if applicable (liability protection)

That's 4-6 cameras for most single-location businesses. A 4-channel or 8-channel NVR handles this perfectly.

IP cameras vs analogue

Go with IP cameras. Analogue (BNC/coaxial) systems are outdated. IP cameras run on your network cable, give you higher resolution, and support remote viewing without extra hardware. The price difference has closed significantly.

Remote viewing matters

The whole point of CCTV for a business owner is checking in when you're not there. Your system should let you view live feeds and playback from your phone, anywhere. If a vendor is selling you a system that only works on-site, skip it.

Remote viewing requires proper network configuration. The cameras need reliable internet, port forwarding or P2P connection, and a mobile app that actually works. We set this up as part of every installation.

Storage: how many days do you need?

Most businesses are fine with 30 days of recording. If something happens, you'll notice within a month. A 2TB drive handles 4-8 cameras at 1080p for about 30 days with motion-based recording. 4TB if you want 60+ days or have more cameras.

Don't let vendors sell you continuous recording if motion-based works for your situation. It uses less storage and makes finding footage easier.

Night vision and outdoor cameras

If you need outdoor cameras (parking, rear entrance, perimeter), make sure they're rated IP66 or IP67 for weather resistance. Night vision range matters: a camera rated for 30m IR will actually give you clear footage at about 15-20m in practice.

What a proper installation includes

It's not just mounting cameras on walls. A proper installation means: correct positioning for coverage without blind spots, structured cabling (not loose cables zip-tied to the ceiling), NVR placed in a secure location, remote access configured and tested, and training so you know how to find and export footage when you need it.
