Map out where you’ll place each camera. Cover entrances, driveways, hallways, and any blind spots.

  • Avoid direct light or glare from windows.

  • Keep cameras at least 8–10 feet high for best coverage.

Secure the mounts using screws and anchors.
Ensure each camera faces its intended target and tighten its angle to prevent movement.
Avoid placing cameras too close to light sources or in areas exposed to heavy rain unless weatherproofed.
