CCTV Repairs in North Woolwich
If your CCTV system has gone offline, cameras have failed, recordings are missing, or remote viewing isn’t working, you need a repair that fixes the root cause and proves the system is stable again. E16 Locksmith North Woolwich provides practical CCTV repairs in North Woolwich for domestic and commercial installations — from single-camera faults to full recorder, network, and power issues.
If you need a new system rather than a repair, see CCTV installation. If your main priority is external coverage (doors, driveway, boundaries), see outdoor CCTV installation. For front-door visibility without a full camera system, digital door viewers may be a better fit for some entrances.

CCTV repair services are available across London City Airport, Royal Victoria, Silvertown Way and Woolwich Manor Way, covering cameras going offline, recording failures, and remote viewing faults.
What we repair
CCTV issues rarely sit in one place. A “camera offline” problem could be a camera fault, a connector fault, a PoE power issue, a recorder channel problem, or a network conflict. Repairs typically cover:
Cameras and image issues
System types and recorders
Recording, playback, and export
Storage and hard drive faults
Power, cabling, and terminations
Network and remote viewing
Settings and optimisation
CCTV repair cases we handle (deeper examples)
Case: All cameras offline
Typical symptoms: no cameras showing, “video loss” across channels, or the recorder shows no feeds.
Common causes: PSU failure, PoE switch/injector failure, recorder power faults, tripped circuits, surge damage.
Repair approach: power-path testing, PoE verification, replacement of failed power components where required, then full channel retesting to confirm stable feeds.
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 a junction, damaged cable, PoE voltage drop, loose termination.
Repair approach: re-terminate ends, replace connectors, test cable integrity, reseal junctions, rebalance PoE load, replace a failed camera only when confirmed.
Case: Live view works but there’s no recording / missing footage
Typical symptoms: empty playback timeline, gaps in recording, “HDD error”, or recording stopped after a change.
Common causes: failed hard drive, incorrect schedule, overwrite disabled, storage full, channel settings misconfigured.
Repair approach: disk health checks, replace a surveillance HDD if needed, correct schedules and overwrite behaviour, verify playback and export from the repaired state.
Case: Recorder won’t boot or keeps rebooting
Typical symptoms: stuck on logo, constant restart loop, loud beeping, overheating.
Common causes: failing PSU, hard drive short/failure, firmware corruption, cooling fan failure.
Repair approach: isolate HDD/PSU, restore stable boot, address cooling, re-verify recording once the recorder is stable again.
Case: Remote viewing stopped after a router or broadband change
Typical symptoms: app offline, P2P/QR pairing not connecting, “device disconnected”.
Common causes: IP/gateway/DNS changes, firewall rule changes, P2P disabled, permissions mismatch.
Repair approach: rebuild network settings, restore secure app pairing, confirm local and remote access, and tighten credentials and permissions as part of handover.
Case: Night image is washed out, white, or full of glare
Typical symptoms: haze, reflective “snow”, poor identification at night.
Common causes: IR reflection off soffits/walls, dirty lens, spider webs on IR cameras, moisture inside housing, wrong angle.
Repair approach: clean and realign, adjust night exposure/IR behaviour where supported, reseal or replace weather-damaged units, then verify night performance after changes.
Case: Coax system interference (lines, noise, rolling picture)
Typical symptoms: hum bars, unstable picture, lines, or ghosting.
Common causes: ground-loop style interference, weak PSUs, damaged coax, poor BNC terminations, low-quality baluns.
Repair approach: improve terminations, replace weak power components, isolate the interference source, repair or replace compromised cable runs.
Case: False motion alerts or missed detections
Typical symptoms: constant alerts from trees/headlights, or no alerts 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 while improving real detections.
Case: Playback is choppy / live view lags
Typical symptoms: buffering, delayed live view, skipping playback.
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)
Typical symptoms: recordings show wrong time, exports don’t match event timing.
Common causes: incorrect time zone/DST settings, time sync not configured.
Repair approach: correct time zone and DST settings, set reliable time sync, verify timestamp accuracy on new recordings.
We also diagnose and repair CCTV systems throughout Pier Parade Post Office, Duke of Wellington, Silvertown War Memorial and Royal British Legion, working across HD, IP, wireless, and hybrid camera setups.
Our CCTV repair process
- Diagnose: check recorder, power, cabling, network, and camera status to pinpoint the true fault source.
- Repair options: clear recommendation to repair, replace, or reconfigure based on reliability and cost-effectiveness.
- Fix and stabilise: complete remedial work and optimise settings for clear images and consistent recording.
- Test and handover: prove live view, recording, playback/export, timestamps, and remote access (where used) from the repaired state.
When a repair becomes an upgrade decision
If key components are repeatedly failing (for example storage, power hardware, or an overloaded recorder), a targeted upgrade can be more reliable than repeated repairs. Where practical, we’ll explain what can be stabilised and what is likely to keep recurring, so you can make a sensible long-term decision.
