1. Planning is the Most Important Step (Site Survey)
- Make a complete map of the area. Mark all entry/exit points (main gate, doors, garage, driveway), blind spots, and high-value areas.
- Decide how many cameras you need and where to place them. Focus on choke points for maximum coverage with fewer cameras.
- Prefer PoE (Power over Ethernet) cameras - one cable handles both power and data, making wiring much easier and cleaner.
2. Correct Height and Angle of Cameras
- Height: Install cameras 8-10 feet (approx. 2.4-3 meters) above the ground. This gives a clear view of faces and prevents easy tampering.
- Angle: Tilt the camera 15o to 45o downward. Too high and you only see the top of heads; too low and faces may not be visible clearly.
- Never point cameras directly toward the sun - it causes glare and washed-out footage.
3. Best Placement Locations
- Front door, back door, and side entrances
- Garage and driveway
- Main gate and compound walls
- In shops/offices: Counter area, store room, and exit points
- Try to cover maximum area with each camera while keeping some overlap so no spot is missed.
4. Lighting and Night Vision
- Install cameras in areas with good lighting. Infrared (IR) lights work in darkness, but avoid reflection (IR light should not bounce back from walls or objects into the lens).
- Always choose waterproof cameras (IP65 or higher) for outdoor use.
5. Wiring and Power Supply
- PoE cameras are the best choice for clean and simple installation.
- Avoid sharp bends in cables. Keep them at least 12 inches away from high-voltage wires to prevent interference.
- Use a stable power supply and add a UPS backup so recording continues during power cuts.
- Protect outdoor wiring with conduit pipes or PVC channels.
6. Software and Settings
- Update the firmware of NVR/DVR before installation.
- Set proper recording schedule: Motion detection + continuous recording.
- Use strong, unique passwords - never leave default passwords.
- Set up remote viewing using secure cloud services or proper port forwarding.
7. Common Mistakes to Avoid
- Installing cameras too high or too low
- Blocking or reflecting IR lights
- Using indoor cameras outdoors
- Insufficient storage space (check HDD capacity properly)
- Pointing cameras toward neighbors' property (privacy issues)
- Skipping testing - always check footage quality in day and night after installation.
8. Pro Tips (2026 Updates)
- Follow DORI standards: Placement should support Detection --> Observation --> Recognition --> Identification.
- For wired systems, hire a professional installer if you are not experienced - small mistakes can become costly later.
- Regular maintenance: Clean dust regularly, keep firmware updated, and check HDD health monthly
