CCTV is only useful if it records the right places, clearly, and keeps footage long enough. Here is how to plan an office CCTV system that works when you need it.
Where to place cameras
- Every entry and exit, facing the door so faces are visible.
- Reception and visitor areas.
- Cash counters, store rooms and server rooms.
- Open work areas and corridors, for overall coverage.
- Parking and loading areas if you have them.
IP cameras or HD analog?
IP cameras offer higher resolution, better remote viewing and run on network cable with power over Ethernet. HD analog cameras cost less and suit simple setups. For new offices, IP cameras are usually the better long-term choice.
How much storage do you need?
Storage depends on the number of cameras, resolution and how many days of footage you want to keep. Many offices keep 15 to 30 days. Motion-based recording and efficient video compression can extend this considerably.
Night vision and lighting
Check how each area looks at night. Infrared cameras work in darkness, while colour night-vision cameras need some ambient light.
Remote viewing and access
Set up mobile viewing for the owners, change default passwords and restrict who can delete footage.
Maintenance
Cameras get dusty, hard disks fail and recordings stop without anyone noticing. A quarterly check, or a CCTV AMC, makes sure the system records when you need it.
