CCTV Repair & Maintenance in Chennai
Troubleshooting offline cameras, power supply unit failures, hard drive errors, and mobile phone disconnection issues for residential and commercial systems across Chennai.
Common CCTV issues we resolve
Most surveillance breakdowns stem from power adapter degradation, loose BNC terminations, or hard disk sector failures. Here is what we diagnose on site.
No Video / Black Screen
Typically caused by a burnt 12V channel on the central SMPS power box, damaged copper core wire, or a rusted outdoor BNC connector.
DVR Beeping / Not Recording
Continuous buzzer beeping indicates the hard drive is unreadable, corrupted, or has failed after years of 24/7 continuous write cycles.
Mobile App Shows "Offline"
Occurs after changing your Wi-Fi router, updating broadband DNS settings, or when the Ethernet link between DVR and router becomes loose.
Flickering / Night Vision Failure
Infrared LEDs require higher amperage. When daytime view is fine but night feed goes dark, power supply voltage drop is usually the culprit.
