Planning Your CCTV Setup
Before purchasing cameras, walk around your property and identify key areas that need monitoring: main entrance, back door, driveway, garden, and any blind spots. Sketch a simple floor plan and mark camera positions. Consider the field of view each camera needs — wide-angle for open areas, narrow for corridors and entry points.
Choosing Camera Locations
Mount cameras 8-10 feet above ground for the best viewing angle. Ensure outdoor cameras are sheltered from direct rain and harsh sunlight. Position cameras to cover each other's blind spots. The main entrance should always have a camera. Place cameras where they can capture faces, not just the tops of heads.
Running Cables (Wired Systems)
For wired systems, plan cable routes before drilling. Use cable conduits to protect wires from weather and tampering. Route cables along walls and ceilings to keep them neat. Each camera needs both a power cable and a video/data cable (or a single PoE cable for IP cameras). Label each cable at both ends for easy maintenance.
Setting Up Wireless Cameras
Wireless cameras are simpler to install. Download the manufacturer's app, create an account, and follow the setup wizard. Ensure your Wi-Fi signal is strong at each camera location — use a Wi-Fi extender if needed. Mount the camera using the provided bracket and screws. Most wireless cameras still need a power source, so plan for nearby outlets or use battery-powered models.
Configuring Your DVR/NVR
Connect all cameras to your DVR (for analog) or NVR (for IP cameras). Configure recording settings: continuous recording uses more storage but captures everything, while motion-triggered recording saves space. Set up mobile viewing by downloading the manufacturer's app and adding your DVR/NVR using its IP address or QR code. Configure alert notifications for motion detection events.
Testing and Optimization
After installation, test each camera during both day and night. Check for blind spots and adjust angles as needed. Verify that motion detection triggers alerts correctly. Ensure night vision provides usable footage. Test remote viewing from your smartphone. Set up a regular maintenance schedule to clean camera lenses and check connections every 3 months.
