Dash cams have narrow field-of-view lenses (usually 140°-170°) compared to home cameras (180°+). Compensate by:

• Elevated corner mounting: Use suction cups or adhesive mounts to position the camera diagonally across a room, maximizing coverage.
• Focusing on choke points:
  • Entryways (records everyone entering/exiting)
  • Hallway intersections (captures movement between rooms)
  • Near valuables (monitors safes or display cabinets)

Overcoming Night Vision Limitations

Most dash cams struggle in low light unless they have infrared (IR) capabilities. Solutions include:

• Adding supplemental lighting: Install motion-activated LED strips near the camera’s view.
• Choosing IR-enabled models: Like the Vantrue N4 mentioned earlier, which can see up to 30 feet in darkness.
• Strategic daytime use: Perfect for monitoring daytime cleaners or contractors when natural light is available.

Pro Tip: Test your setup by walking through the monitored area at different times of day. Check playback to identify blind spots—you might need to adjust angles or add a second camera.
