1. Clean Camera Lenses Regularly

Dirt, dust, and fingerprints can make footage blurry. Clean lenses with a soft microfiber cloth every few weeks for clear video quality.

2. Check Power Supply and Cables

Loose connections or damaged power cables can cause cameras to stop recording. Inspect cables and power adapters regularly.

3. Test Recording and Playback

Regularly check if your DVR/NVR is recording properly. Play back random footage to confirm data is being saved without errors.

4. Update Firmware

Manufacturers release firmware updates to fix bugs and security issues. Log in to your DVR/NVR or IP camera settings and check for updates every few months.

5. Monitor Storage Space

Ensure your hard disk has enough free space. If the disk is full, old footage may overwrite new recordings. Replace hard disks every 3–4 years to avoid sudden failure.

6. Inspect Camera Positioning

Strong winds or accidental bumps may change the camera’s angle. Check positioning and adjust to cover the required area.

7. Backup Important Footage

For critical events, backup footage on external drives or cloud storage. Don’t rely only on the DVR/NVR storage.

8. Secure Your Network (For IP Cameras)

Change default passwords, enable encryption, and use strong firewalls to prevent hackers from accessing your CCTV remotely.
