Placement Beats Megapixels
We are often called to sites where expensive cameras failed to capture an incident because they were pointed at the wrong place. Camera placement is a discipline, and it is the part of a CCTV project where experience pays for itself. Here is how our engineers plan coverage.
Start with Purpose, Not Positions
For each area we ask what the footage must achieve, using the standard levels: monitor (see that something happened), detect (see a person is present), recognise (identify someone you know) and identify (evidence quality face capture of a stranger). Identification needs far more pixels on the target than monitoring, which drives camera choice and mounting distance.
Priority Zones for Business Premises
- Entry and exit points — a face height camera at every door used by people, positioned so faces are captured on entry when people look forward.
- Cash and valuables — billing counters, safes and cash rooms, with a wide context view plus a tight detail view.
- Movement corridors — passages and staircases that anyone must cross, which multiply coverage cheaply.
- Perimeter and parking — boundary walls, gates and vehicle areas with adequate infrared reach.
- The recorder itself — one camera should watch the rack holding the NVR.
Common Mistakes We Fix
- Cameras mounted too high, recording the tops of heads instead of faces
- Cameras facing glass doors or east-west gates, blinded by glare at sunrise or sunset
- Wide angle lenses used for gates, so number plates become unreadable smudges
- Foliage and signage growing into the field of view over time
- Dark zones at night where infrared range was never checked
The Survey Makes the Difference
We walk the site at survey, check lighting conditions, test angles and give you a marked floor plan before quoting. That plan becomes the contract for coverage. Book a survey through app.techguru.co.in or call +91-8800567676.
