A camera you can't rely on is worse than no camera at all — and the most common reason CCTV fails to capture an incident is a blind spot. Smart camera placement, not more cameras, is what delivers complete coverage.
Blind spots happen at corners, directly below wall-mounted cameras, behind pillars and large shelving, and in areas washed out by backlight. The fix is overlapping fields of view: each camera should see the base of the next, so a person can never move through your property unseen.
The Overlap Rule and Mounting Heights
Mount cameras 8–10 feet high — high enough to be out of reach, low enough to capture identifiable faces. Cover every entry and exit head-on, then fill interior coverage with overlapping zones. Use wide-angle cameras for open areas and a dedicated camera for each choke point (gates, stairwells, cash counters). Avoid pointing cameras into direct sun or bright windows. A professional site survey maps sightlines before installation so you pay only for the cameras you truly need.
