Recording: DVR/NVR faults, channel issues, recording schedules, playback/export problems
Storage: surveillance hard drives, disk errors, overwrite issues, capacity management
Power: PSUs, splitters, PoE injectors, PoE switches, loose feeds, surge-related failures
Cabling: Cat5e/Cat6, coax, connectors (RJ45/BNC), baluns, junction boxes, water-damaged joints
Network: IP conflicts, PoE budget issues, switch faults, dropouts, bandwidth bottlenecks
Remote viewing: app/P2P issues, QR pairing, router changes, password resets (owner authorised)
Settings: motion/analytics tuning, sensitivity, schedules, image optimisation, timestamps
Display: HDMI/VGA output, resolution mismatch, monitor “no signal” faults

Common CCTV faults we fix

No image, black screen, frozen video, flickering or rolling picture
Cameras offline (one, several, or all)
Night vision not working / overexposed at night
Blurry image, focus issues, fogging, water ingress
Recorder not booting, crashing, beeping, or showing errors
No recording, missing footage, playback not working
Remote viewing/app not connecting
Motion alerts not triggering (or too many false alerts)
Interference on coax systems (noise, lines, ghosting)
Hard drive warnings, storage full, or overwriting incorrectly

CCTV repair cases we handle (deeper examples)

Case: All cameras offline

Typical symptoms: no cameras showing / “video loss” across all channels
Common causes: power supply failure, PoE switch/injector failure, recorder PSU fault, tripped circuit, surge damage
Repair approach: power-path testing, PoE verification, swap/replace PSU or PoE hardware, restore stable feed and re-test all channels

Case: One or two cameras keep dropping out

Typical symptoms: intermittent image, camera offline at certain times, random reboots
Common causes: failing connector, water in junction, damaged cable, PoE voltage drop, loose termination
Repair approach: re-terminate ends, replace connectors, test cable run, reseal junctions, adjust PoE load or replace camera if failed

Case: No recording / missing footage

Typical symptoms: live view works but playback is empty, gaps in timeline, “HDD error”
Common causes: failed hard drive, wrong schedule, overwrite disabled, storage full, incorrect channel settings
Repair approach: disk health checks, replace surveillance HDD if needed, correct schedules, verify recording mode, confirm playback and export

Case: Recorder won’t boot or keeps rebooting

Typical symptoms: stuck on logo, constant restart, loud beeping, overheating
Common causes: failing PSU, HDD short/failure, firmware corruption, fan failure/overheating
Repair approach: isolate HDD/PSU, test cooling, restore stable boot, update/configure where appropriate, re-check recording

Case: Remote viewing stopped after router or broadband change

Typical symptoms: app offline, QR/P2P not connecting, “device disconnected”
Common causes: IP address changes, DNS/gateway changes, blocked ports (where used), router firewall rules, P2P disabled
Repair approach: rebuild network settings, restore app pairing, confirm local + remote access, secure passwords and permissions

Case: Night image is white, washed out, or full of glare

Typical symptoms: bright haze, reflective “snow”, poor identification at night
Common causes: IR reflection off soffits/walls, dirty lens, spider webs, wrong camera angle, moisture in housing
Repair approach: clean/realign camera, adjust IR/exposure settings, reseal or replace weather-damaged units, verify night performance

Case: Coax system interference (lines, noise, rolling image)

Typical symptoms: horizontal lines, hum bars, unstable picture
Common causes: ground loop, poor power supply, damaged coax, bad BNC termination, low-quality baluns
Repair approach: improve terminations, replace weak PSUs, isolate interference source, repair cable run, stabilise signal

Case: False motion alerts or missed detections

Typical symptoms: constant alerts from trees/headlights, or nothing triggers at all
Common causes: sensitivity too high/low, poor motion zones, incorrect schedules, shadows/glare, camera placement
Repair approach: tune motion zones, sensitivity, schedules, and image settings to reduce false alerts and improve real detections

Case: Playback is choppy / live view lags

Typical symptoms: skipping playback, buffering, delayed live view
Common causes: bitrate too high, weak network links, PoE switch congestion, HDD struggling, recorder overloaded
Repair approach: optimise stream settings, check network throughput, address storage bottlenecks, confirm smooth playback and export

Case: Timestamps wrong (time drift / daylight saving issues)

Typical symptoms: incorrect time on recordings, exports show wrong event time
Common causes: incorrect time zone, NTP not set, daylight saving misconfigured
Repair approach: correct time zone/DST, set reliable time sync, verify timestamp accuracy on recordings

Case: PTZ camera not moving or presets not working

Typical symptoms: no pan/tilt/zoom response, presets failing, partial movement
Common causes: power issue, control wiring/config errors (where applicable), IP config faults, failed motors
Repair approach: verify power/control, correct configuration, restore presets, replace unit if hardware failure confirmed

Our CCTV repair process

1) Diagnose: check recorder, power, cabling, network, and camera status to pinpoint the fault
2) Repair options: clear recommendation to repair, replace, or reconfigure based on reliability and cost
3) Fix and stabilise: complete remedial work and optimise settings for clear images and consistent recording
4) Test and handover: confirm live view, recording, playback, and remote access (where used)
