How to Choose a Commercial CCTV System for Your Business in Montreal

1. Understand Your Core Objectives: Deterrence vs. Forensic Evidence

Before purchasing hardware, clarify what you need your security cameras to achieve. Simple general observation requires modest 1080p resolution, while positive facial identification at an entrance or license plate capture across a commercial parking lot demands 4K (8-Megapixel) resolution with specialized optical focal lengths.

2. Why Commercial Buildings Require Hardwired Power over Ethernet (PoE)

While consumer Wi-Fi cameras are marketed aggressively for residential DIY setups, commercial environments demand commercial PoE (Power over Ethernet). Running a single Cat6 network cable provides both gigabit data transmission and direct power from a central PoE switch, eliminating batteries, wireless dropouts, and Wi-Fi signal interference from industrial machinery.

3. Camera Housing Types: Dome, Bullet, or Turret?

• Vandal-Resistant Domes (IK10 rated): Ideal for low ceilings, building lobbies, retail aisles, and public areas where cameras must resist impacts or deliberate tampering.
• Bullet Cameras: Visually prominent deterrence for building perimeters, fence lines, and loading docks with long-range infrared night vision up to 200 feet.
• Turret / Eyeball Cameras: The modern industry favorite for outdoor facades because they prevent glass dome reflection glare and spider web obstructions.

4. Sizing Video Storage and Frame Rates

A frequent error is underestimating storage capacity. In Quebec, commercial insurance underwriters and corporate auditors frequently mandate a minimum of 30 days of continuous recording. By employing modern H.265+ smart video compression and motion-priority recording, an 8-camera 4K system requires roughly 8 to 16 Terabytes of dedicated surveillance-grade storage (such as Western Digital Purple or Seagate SkyHawk drives).

5. Complying with Quebec Law 25 and Employee Privacy

In Quebec, commercial video surveillance must strictly comply with Law 25 (Act respecting the protection of personal information). Employers cannot monitor employee workspaces continuously without justifiable cause, and cameras in breakrooms, restrooms, or locker rooms are strictly illegal. High-visibility bilingual warning notices must be posted at all facility entryways.
