What to look for when buying

Choosing a CCTV system is not just about picking the most expensive camera. You need reliability, resolution, and functionality tailored to your specific risk profile. Use these three tips to guide your purchase:

1. Prioritise Resolution (4MP or 4K minimum): In a commercial setting, resolution is paramount. While 1080p cameras were standard years ago, modern activity requires at least 4MP (2K) or ideally 4K (8MP) cameras. Higher resolution means clearer facial recognition and better evidence capture.

2. Check for Advanced AI Features: Modern cameras are not just video recorders; they are smart monitors. Look for AI features that differentiate between people, vehicles, and animals. This dramatically reduces "false alarms"-a common headache with older, motion-sensor systems-and ensures security staff only respond to genuine threats.

3. Consider Power over Ethernet (PoE+): PoE is the gold standard for CCTV wiring. It allows a single Ethernet cable to transmit both power and data to the camera. This simplifies installation, reduces wiring clutter, and makes the system much more reliable than systems that require separate power sources.
