What to look for when buying

Buying a commercial CCTV system involves more than just selecting the highest resolution. Here are three critical factors to ensure your system is effective, compliant, and future-proof.

1. Resolution vs. Codecs: While 4K (8MP) sounds best, consider the compression codec (H.265+). Modern cameras use advanced codecs to deliver ultra-high resolution footage while minimizing the required storage space and network bandwidth. A high-resolution camera with an outdated codec will quickly overwhelm your NVR.

2. Coverage and Blind Spots: Do not rely on a single camera to cover everything. Map your premises and identify all potential blind spots-this includes corners, under stairwells, and areas shielded by large objects. You may need a combination of Dome, Bullet, and PTZ cameras to achieve full, overlapping coverage.

3. Data Retention and Compliance (GDPR): In the UK, compliance is paramount. When purchasing, ensure the system allows you to easily set retention policies. You must be able to specify how long footage is kept and who has access to it. Always ensure the system signage is visible and clearly informs the public of the CCTV presence.
