Installing a CCTV system is a great way to enhance security, but mistakes during installation can lead to poor performance, blind spots, or even system failure. To help you get the most out of your security cameras, we’ve listed the 10 most common CCTV installation mistakes and how to avoid them.
1. Poor Camera Placement
Mistake: Placing cameras too high, too low, or in areas with obstructions.
Solution:
- Install cameras 7-10 feet high for optimal coverage.
- Avoid pointing cameras directly at light sources to prevent glare.
- Ensure they cover all critical entry points (doors, windows, driveways).
2. Ignoring Lighting Conditions
Mistake: Installing cameras in low-light areas without proper night vision or IR support.
Solution:
- Use IR (infrared) cameras for nighttime surveillance.
- Avoid pointing cameras at bright lights to prevent overexposure.
- Test camera visibility at different times of the day.
3. Using Weak or Exposed Cables
Mistake: Running cables openly, making them vulnerable to damage or tampering.
Solution:
- Use conduit pipes to protect cables.
- Choose weatherproof cables for outdoor installations.
- Keep cables away from electrical wires to avoid interference.
4. Not Securing the DVR/NVR Properly
Mistake: Leaving the DVR/NVR in an easily accessible location.
Solution:
- Place the recorder in a locked cabinet or hidden spot.
- Ensure proper ventilation to prevent overheating.
- Use strong passwords to protect access.
5. Skipping Camera Angles Testing
Mistake: Assuming the camera angle is perfect without testing.
Solution:
- Do a live test before finalizing installation.
- Check for blind spots and adjust angles accordingly.
- Use a monitor to verify the field of view.
6. Overlooking Weather Protection
Mistake: Installing non-weatherproof cameras outdoors.
Solution:
- Always use IP66 or higher-rated cameras for outdoor use.
- Install protective housings if needed.
- Ensure cameras are shielded from direct rain or extreme heat.
7. Incorrect Lens Selection
Mistake: Using the wrong lens (too wide or too narrow) for the area.
Solution:
- Wide-angle lenses (2.8mm) for broad areas.
- Narrow lenses (6mm+) for long-distance focus (like driveways).
- Test different lenses before finalizing.
8. Weak Wi-Fi for Wireless Cameras
Mistake: Installing wireless cameras in areas with poor Wi-Fi signals.
Solution:
- Check Wi-Fi strength before installation.
- Use Wi-Fi extenders if needed.
- Prefer wired connections for critical areas.
9. Not Setting Up Remote Viewing Properly
Mistake: Failing to configure mobile/remote access.
Solution:
- Ensure the DVR/NVR is connected to the internet.
- Use a reliable security app (like Hik-Connect, Dahua DMSS).
- Enable port forwarding or P2P for remote access.
10. Forgetting Regular Maintenance
Mistake: Installing cameras and never checking them again.
Solution:
- Clean camera lenses periodically.
- Check for firmware updates.
- Test recording and motion detection regularly.
FAQ: CCTV Installation Mistakes
Q: How high should I install my CCTV cameras?
A: 7-10 feet is ideal—high enough to avoid tampering but low enough to capture clear faces.
Q: Can I install CCTV cameras myself?
A: Yes, but avoid common mistakes like poor placement or weak cables. Follow the manufacturer’s guide or hire a professional.
Q: Do wireless CCTV cameras need power?
A: Yes, they still need a power source (battery or wired power). Only the data transmission is wireless.
Q: How do I prevent CCTV glare at night?
A: Avoid pointing cameras at bright lights and use IR-cut filters for better night vision.
Q: How often should I check my CCTV system?
A: Perform a monthly check for camera angles, recording quality, and cable conditions.
Final Thoughts
Avoiding these common CCTV installation mistakes ensures better security coverage and longer-lasting cameras. Always plan before installing, test angles, and protect your system from weather and tampering.
