PTZ vs Fixed CCTV Cameras: Which Should You Buy?

The fundamental trade-off

A PTZ's strength is its weakness: a 25× zoom that can read a plate at 200m is, at that moment, blind to the other 350 degrees. Recorded retrospectively (most systems, most of the time), a PTZ parked on preset 1 while the incident happened at preset 3 is a recurring disappointment we're called to autopsy. Fixed cameras have no such moods: the dock door camera saw the dock door tonight, last week and at 3:47am on the night in question. Systems are therefore designed fixed-first; PTZ is a capability you add for a reason, not a default 'better camera'.

When PTZ genuinely earns its price

• Auto-tracking on detection: radar/thermal/analytics hand the PTZ a target and it follows — the modern pattern that fixes the 'pointing wrong way' problem (standard on our site-tower deployments)
• Live-monitored sites: ARC operators or gatehouses actively driving the camera — investigation and challenge in real time
• Large open areas: yards, car parks, sports grounds where one PTZ on patrol presets + event recall covers what would need 6–10 fixed units
• Long-range identification on demand: reading plates/faces at distances fixed lenses can't, after detection layers cue it
• Construction phases: a tower PTZ surveying a changing site beats re-aiming fixed cameras monthly

Costs and the hybrid designs that work

Money: quality fixed cameras £150–£600 installed each; capable PTZs £400–£2,000+, with auto-tracking and laser/long-IR models at the top. The designs that satisfy: fixed cameras for every entrance, dock, till and choke point (the evidence layer) + one or two PTZs with auto-tracking covering open ground (the response layer) + detection (analytics/thermal/radar) telling the PTZ where to look. The design that disappoints: replacing four fixed positions with 'one PTZ that does everything' — it will, but only one thing at a time, and rarely the right one unattended.
