Effective cctv surveillance provides numerous advantages, including:
- Crime prevention
- Evidence collection
- Employee monitoring
- Customer safety
- Property protection
- Reduced financial losses
- Increased peace of mind
- Better emergency response
When criminals notice visible cameras, many choose not to commit crimes because they know their actions are being recorded.
Camera Placement Makes the Biggest Difference
Even the most advanced camera cannot perform well if installed in the wrong location.
Proper placement allows cameras to capture clear images of entrances, exits, driveways, parking areas, hallways, cash registers, warehouses, and other critical locations.
Common locations include:
- Front doors
- Back entrances
- Garages
- Parking lots
- Reception areas
- Elevators
- Stairways
- Storage rooms
- Loading docks
