What to look for when buying

Choosing a camera is only half the battle. The system components (NVR, cabling, storage) are equally crucial for reliable operation. Keep these three tips in mind to ensure your system is effective and compliant.

1. Prioritise NVR Over Simple SD Cards: While cameras often advertise local SD card storage, commercial security demands long-term, reliable retention. A dedicated Network Video Recorder (NVR) provides centralized management, higher data integrity, and allows you to easily expand your storage capacity as your needs grow.

2. Check for WDR and Low-Light Performance: Commercial buildings have highly variable lighting (e.g., sun streaming through windows, bright overhead lights). Look specifically for cameras with Wide Dynamic Range (WDR) capability. This ensures that areas that are too bright or too dark are captured in usable detail, preventing blinding or underexposed footage.

3. Factor in UK Data Privacy Law (GDPR): Before purchase, consult with your installer to ensure the system meets local GDPR standards. This means considering signage, data retention policies, and limiting recording areas strictly to those necessary for security purposes. An expert installer will guide you through compliance.
