Entrances first
Doors, gates and driveways are often more useful than general wide views because they capture people entering or leaving.
Avoid mounting too high
High cameras may see a lot, but they often miss facial detail. Placement should match the purpose.
Use lighting wisely
Backlight, reflective walls and poor night lighting can reduce image quality.
Plan for playback
Footage should show useful events clearly, not just provide a general overview.
Need site-specific advice?
Photos, a rough floor plan, existing equipment details and a short explanation of the issue are usually enough to begin a practical discussion.
