Camera gone black, image hazy at night, or no footage when you need it? Here is how to narrow it down before anyone climbs a ladder.
Most CCTV faults fall into three groups: no video (one camera or all of them), a blurry or washed-out image, and a recorder that has stopped recording. Start by asking whether one camera or every camera is affected: all cameras down points to the recorder, its power or the screen; one camera down points to that camera’s cable, joint or power. Blur is usually a dirty or fogged lens, spider webs or night-time reflection. A recorder that stops recording is most often a failing hard disk or a setting changed after a power cut. A published Klang Valley rate card puts an ad-hoc service call at RM150–RM250 per visit, with parts on top.
Before calling anyone, look at the recorder screen or the phone app and note exactly what you see. The single most useful question is how many cameras are affected, because it splits the problem in half.
When the whole system is dark, work from the recorder outwards. Check that the recorder is powered and its lights are on, that the monitor is on the right input, and that nothing was unplugged during cleaning or renovation. A recorder that keeps restarting, or shows a fault message about its disk, is a recorder problem.
Power cuts and storms are the usual trigger. A recorder plugged straight into a wall socket loses power in an outage and may not come back cleanly; a surge can damage its power supply or its network port. Our CCTV surge protection guide explains what surge damage looks like and what to do after a storm.
If only one camera has gone, the fault is somewhere on its own run. The common causes, roughly in order:
A technician usually swaps the camera onto a known-good cable or port first. If the camera works there, the cable or power is the problem; if not, the camera is.
Blur is rarely a broken camera. Check the simple causes first:
Cameras switch to infrared at night. If the night image is white, hazy or glowing, the infrared light is bouncing back off something close: an eave, a wall, a dirty dome or a spider web. Moving or re-angling the camera often fixes it. If the night image is completely dark while daytime is fine, the infrared lights or the day/night switch may have failed. Insects are attracted to the light, which is why webs are worse on cameras that see a lot of night use.
This is the most dangerous fault, because the live view looks normal and nobody notices until they need the footage. Check playback every few weeks. When recording stops, the usual reasons are:
Our CCTV hard disk guide explains how many days a disk holds and why a surveillance-grade drive matters for a recorder that never stops writing.
If the cameras record normally but the phone app shows the system offline, the problem is usually the internet link, not the cameras. A new router, a changed Wi-Fi password, an internet outage or an expired app login are the common causes. Check that the recorder is still connected to the router and that the internet itself is working before assuming the recorder has failed.
| Symptom | Likely cause | First check |
|---|---|---|
| All cameras black | Recorder, its power, or the monitor input | Recorder lights, power point, monitor input |
| One camera black | Camera cable, joint, power or the camera | Swap to a known-good cable or port |
| Cameras drop out in rain | Water at a joint, or power drop | Outdoor joints and junction boxes |
| Blurry by day | Dirty lens, webs, focus, low quality setting | Clean the lens; check recording settings |
| White or hazy at night | Infrared reflecting off something close | Eaves, walls, dome and webs near the lens |
| Live view fine, no playback | Disk failure, disk full, or settings | Disk status and overwrite setting |
| Offline on phone only | Internet, router or app login | Router connection and internet service |
A failed disk, adapter or single camera is a repair. The harder decision comes when an old system has several faults at once. If the recorder has failed on an older analog system, a like-for-like recorder keeps the existing cameras and cables; moving to IP usually means new cameras and often new cable. Our IP vs analog CCTV guide explains the trade-off, and the CCTV installation cost guide covers what a new system costs.
These figures come from ClickBina’s CCTV cost guide, which quotes one published Klang Valley rate card and typical retail prices.
| Item | Indicative cost | Notes |
|---|---|---|
| Ad-hoc service call | RM150–RM250 per visit | Diagnosis, realignment and configuration; parts on top |
| 2TB surveillance hard disk | From RM234 per drive | A continuous-write drive, not a desktop drive |
| Site visit for a wider renovation job | RM150 | Waived if you go ahead |

CCTV work is not one of ClickBina’s own listed trades, so we do not promise a repair ourselves. WhatsApp us your job details for a quote: how many cameras, whether it is analog or IP if you know, and exactly what you see (which cameras, day or night, live or playback). We reply within the hour. If the CCTV is part of a wider renovation, ClickBina handles whole-house refurbishment and coordinates the trades on one job, with a flat price, no hidden charges, and a site visit of RM150, waived if you go ahead.
