CCTV camera installation and troubleshooting

CCTV camera installation and troubleshooting

1. Plan Your Surveillance System

Identify coverage areas (entrances, driveways, backyards, etc.)

Choose between wired (DVR-based) and wireless/IP (NVR-based) systems

Select camera types: Dome, Bullet, PTZ, etc.

2. Mount the Cameras

Use wall or ceiling mounts

Drill holes and use screws and anchors for stability

Ensure proper tilt and field of view

3. Run Cables (for wired systems)

Use coaxial + power cable for analog cameras

Use Ethernet (Cat5e/Cat6) for IP cameras with PoE (Power over Ethernet)

Conceal cables to prevent tampering

4. Connect to DVR/NVR

For DVR: Connect BNC cables and power

For NVR: Connect Ethernet cables to PoE switch or router

5. Power the System

Use power adapters or PoE switches

Verify LEDs on cameras are lit

6. Monitor Setup

Connect DVR/NVR to a monitor using HDMI/VGA

Follow setup wizard for date/time, recording, and camera configuration

7. Remote Access

Connect the system to your internet router

Use the system's app or software (e.g., Hik-Connect, XMEye, iVMS, etc.)

🛠️ CCTV Troubleshooting Guide

No Video Feed

This is often due to a loose cable or a faulty camera. Start by checking all the connections, and try swapping out the cables or the camera itself to isolate the issue.

Black Screen

This typically points to a power failure or a damaged video output port—test the system with a different power adapter or try connecting the camera to another port.

Blurry Image

A blurry image is usually caused by a dirty lens or poor focus. Clean the lens and adjust the focus or zoom to resolve the issue.

Night Vision Not Working

The infrared (IR) LEDs might be faulty or not receiving power. Inspect them at night to see if they glow red (if applicable), and replace the camera if necessary.

DVR/NVR Not Detecting Camera

This may be due to an incompatible signal format or incorrect input port. Make sure the camera and recording device are compatible (e.g., AHD, TVI, CVI) and that their resolution settings match.

Remote Access Fails

Common causes include incorrect IP settings or blocked router ports. Confirm the IP configuration and enable UPnP or manually set up port forwarding.

Video Playback Missing

This could indicate that the hard disk drive (HDD) is not installed, has failed, or hasn’t been formatted. Reinstall or format the HDD and check for hardware issues.

Motion Detection Not Working

The problem may lie in the detection zone or sensitivity settings. Adjust the detection area and increase the sensitivity level to ensure motion is properly recorded.
