Experiencing "No Video", black screens, continuous DVR beeping, offline phone apps, or blurry night vision? Our experienced CCTV technicians in Lucknow identify the root cause rapidly and repair it with genuine spare parts.
Most camera failures are caused by burnt SMPS power supply channels, rusted BNC pin connectors, rodent cable damage, or failed DVR hard disk partitions. Here is what we diagnose on-site:
Usually caused by a dead 12V channel in the SMPS box, damaged video balun, or broken copper core inside the coaxial cable.
Indicates AC ground hum, loose BNC terminal crimping, or electrical interference from nearby inverter and motor wiring.
Signals a failed hard drive (HDD bad sectors), IP conflict on local LAN, or video loss alarm on an active channel.
Caused by changed router Wi-Fi gateway, bad LAN patch cord, DNS failure, or cloud P2P platform authentication timeout.
We carry genuine multi-brand spares in our technician repair kits — including 4-channel, 8-channel, and 16-channel regulated SMPS power supplies, gold-plated BNC connectors, Cat6 connectors, HDMI/VGA adapters, and 12V 2A adapters. We never force you to buy unnecessary hardware.
