Take the time to map out your camera placements, consider power sources, and plan cable runs if you're opting for a wired system. This proactive approach will save you time and frustration down the line.

Creating a Site Map

Start by sketching a simple map of your property. Mark all potential entry points (doors, windows), driveways, garages, and any areas you want to monitor closely. For businesses, include entrances, exits, reception areas, sensitive zones, and parking lots. On this map, indicate where you envision placing each camera. Consider the camera's field of view to ensure adequate coverage and overlap where necessary. Think about potential obstructions like trees or buildings that might block the view. Also, note existing power outlets or network ports that you can utilize, or identify areas where new power sources or network cables will be required.

Determining Camera Placement

Strategic placement is key to effective surveillance. Here are some general guidelines:

  • Entry Points: Cover all main entrances and exits. Position cameras high enough to deter tampering but low enough to capture clear facial details.
  • Vulnerable Areas: Ground-floor windows, back doors, and secluded areas should be monitored.
  • High-Traffic Zones: Driveways, walkways, and common areas within a business.
  • Blind Spots: Identify areas not covered by existing cameras and place new ones to fill these gaps.
  • Height and Angle: Mount cameras at least 8-10 feet high to prevent easy access. Angle them downwards to capture faces and avoid capturing too much sky, which can wash out images.
  • Lighting: Consider how natural and artificial light will affect the camera's view, especially at different times of day and night. Avoid pointing cameras directly into bright light sources.

Power and Connectivity Considerations

For wired systems, you'll need to run cables for both power and data. This might involve drilling through walls, running cables through attics or crawl spaces, or using outdoor-rated conduit. Plan these routes carefully to minimize visible wiring and ensure they are protected. For wireless cameras, you'll still need a power source for each camera (unless they are battery-powered). Wi-Fi cameras require a strong and stable wireless signal in their intended location. Test your Wi-Fi strength in these areas before purchasing or installing. Consider a Wi-Fi extender or mesh network if signal strength is an issue.
