Top 10 Common CCTV Camera Problems and How to Fix Them (Complete Guide for 2025)

Night Vision Not Working

IR LEDs help the camera record in low light, but sometimes the night vision becomes blurry or completely dark.

Causes

Dust or dirt on the lens

IR LEDs not turning on

Low power supply

Camera placement too close to light sources

Fix

Clean the lens and check for reflection issues. If IR lights still don’t work, your camera may need CCTV night vision repair or replacement.

DVR Not Recording

If your DVR is not recording, your footage is not being saved—this is a major security risk.

Reasons

Faulty hard disk

Full storage

Wrong recording settings

Loose SATA cable

DVR software issue

Fix

Restart the DVR, check recording mode, and make sure the hard disk is functioning. If still unresolved, book DVR repair in Delhi.

CCTV Camera Showing Blurry Images

Blurry video reduces the effectiveness of your CCTV system.

Causes

Out-of-focus lens

Dirty camera dome

Faulty camera sensor

Poor quality wiring

Wrong angle positioning

Fix

Clean the camera and adjust the focus ring. If image quality remains poor, consider replacing cables or upgrading to HD cameras

WiFi / IP Camera Not Connecting to Network

If your video feed flickers, flashes, or shows interference lines, it may indicate an electrical or wiring problem.

Causes

Loose connectors

Power supply fluctuation

Poor-quality BNC cables

LED lights interference

Fix

Replace low-quality cables and ensure stable power. A technician can identify electrical issues and perform safe repairs.

CCTV DVR Beeping Continuously

A beeping DVR usually indicates a hardware warning.

Possible reasons

Hard disk failure

Overheating

Loose SATA cable

Low power

Fix

Check ventilation and reconnect cables. If the beeping continues, your DVR needs professional inspection.

Mobile App Not Showing CCTV Footage

Remote viewing is essential for home and business security. But sometimes the footage doesn’t appear on your phone.

Reasons

Internet issues

Wrong port forwarding

Offline DVR

Expired cloud service

Wrong device ID or IP

Fix

Restart your router and DVR. Re-scan the QR code in the app. If you still can’t view footage remotely, get CCTV remote viewing setup assistance.

CCTV Camera Not Recording at Night

Sometimes cameras work in the daytime but stop recording at night.

Reasons

Insufficient lighting

IR light failure

Wrong recording schedule

Hard disk error

Fix

Enable 24×7 recording in the DVR settings or adjust motion detection sensitivity.

Complete CCTV System Shutdown

When the entire system stops working, it usually indicates a major power or equipment issue.
