Business Security Systems and Cameras

Why integrating security with your network matters

A common pattern: cameras installed by a security trade, network installed by an IT provider, alarms installed by a third — and when something goes wrong, each blames the other. We avoid that by designing the cabling, network and security together. PoE budgets are calculated, VLANs are configured, storage is sized, and one team is on the hook for the whole thing.

The result is a security system that’s reliable, easy to use, easy to extend, and supported by people who understand it end-to-end.

Storage and retention decide the hardware

This is the decision most often left until last, and it’s the one that determines what you buy.

How long footage is kept depends on four things: how many cameras, at what resolution, at what frame rate, and how much movement they see. A camera watching an empty yard overnight records very differently from one over a busy entrance.

We start from the retention period the business actually needs — usually driven by insurance requirements, how long it typically takes to discover an incident, or an industry obligation — then size storage to that with headroom. Buying a recorder first and discovering the retention it delivers is the wrong way round. Recording drives are also consumables designed for continuous write, so they should be planned for replacement rather than treated as permanent.

Where UniFi Protect fits

For businesses already running UniFi networking, UniFi Protect is often the most economical option: cameras share the same PoE switching, cabling and management console, and there are no per-camera licence fees. When a camera drops offline, the same interface shows the switch port and whether PoE is being delivered.

A traditional NVR still wins where a site needs specialist camera types, deep integration with alarm monitoring or analytics platforms, very long retention across many cameras, or compliance-grade evidence handling. We’ll say which applies rather than fitting the platform we prefer.

Door access is worth considering at the same time. UniFi Access runs on the same console, and where doors and cameras are both on the plan the cabling and switching overlap substantially — doing them together costs far less than returning later.

Recording people brings obligations

Cameras create records about identifiable people, and that deserves a deliberate decision rather than a default.

Worth settling before installation: what’s being recorded and why, whether signage adequately notifies people, how long footage is kept and what justifies that period, who can access it, and how access requests are handled. State surveillance devices legislation also applies and differs between jurisdictions, particularly around areas where people expect privacy.

None of this is a reason to avoid cameras. It’s a reason to decide retention and access early — which, usefully, also produces a better-designed system.

Cabling and power come first

Cameras need cable to the right places, switches with enough PoE budget for the whole eventual load rather than today’s count, and a comms room with space and ventilation for the recorder.

Where a site is being cabled anyway — a fit-out, a move, a refresh — running camera cabling at the same time is dramatically cheaper than coming back. Fixed cabling must be installed by an ACMA registered cabler, and camera runs are no exception.
