Common CCTV Faults We Fix
| Symptom | Typical Cause |
|---|---|
| Camera shows no picture | Power/cable fault, or camera failure |
| Not recording | Storage full, drive failure, or settings issue |
| Night vision not working | IR LED failure or dirty lens |
| Can't view remotely | Network/router configuration issue |
| System offline after power cut | NVR/power supply fault |
Why CCTV Systems Fail More Often in MBZ City
Mohammed Bin Zayed City's mix of villas and townhouses means tighter plot boundaries than Khalifa City, which changes the fault pattern: cameras mounted closer together with overlapping coverage mean one failed camera creates a bigger blind spot than expected. We also see more mixed-brand systems here than elsewhere — properties bought or rented with an existing CCTV setup nobody fully documented, often combining two or three different manufacturers installed at different times.
The practical takeaway: we start every MBZ City repair call by identifying exactly what's installed before touching anything, since undocumented mixed-brand systems are the norm rather than the exception here.
Quick Checks Before You Call a Technician
A few faults can be ruled out in under five minutes and save you a service call:
- No picture at all: confirm the PoE cable or power adapter is firmly seated at both ends — heat causes connectors to loosen over time.
- Not recording: check the NVR's storage status in its menu. A full hard drive is one of the most common "not recording" causes and is a free fix if overwrite settings are configured correctly.
- Blurry or washed-out night vision: wipe the lens and IR window with a soft, dry cloth — dust buildup on the housing is the single most common night-vision complaint we get.
- Can't view remotely: restart your router first. Many "app not connecting" issues are actually a change in your internet provider's IP address, not a camera fault.
If the fault is still there after these checks, it's a genuine hardware or wiring issue and worth booking a technician rather than troubleshooting further yourself.
What Happens During a Repair Visit
- Diagnosis (15-30 minutes): our technician checks power, cabling, storage health, and camera/NVR firmware to pinpoint the exact fault.
- Quote before any work: you get a clear price for parts and labor before we touch anything — no work starts without your approval.
- Repair or replace: most faults are fixed on the same visit since our vans carry common parts (PoE injectors, cables, connectors, small NVR/HDD stock).
- Test and handover: we test recording, night vision, and remote viewing together with you before we leave, so you know it's genuinely fixed.
Repair Cost Guide
Minor faults (loose connections, settings, cleaning) typically cost AED 100-250. Camera or NVR replacement due to hardware failure ranges AED 300-1,200 depending on the part needed. We always confirm the cost before starting work — no surprises.
| Repair Type | Typical Cost (AED) |
|---|---|
| Diagnosis / callout (waived if repair proceeds) | 100-150 |
| Cable/connector repair per point | 100-250 |
| Single camera replacement (4MP) | 300-550 |
| Power supply / PoE injector replacement | 150-350 |
| NVR/DVR unit replacement | 600-1,200 |
| Hard drive replacement (2-4TB surveillance-grade) | 350-650 |
Brands We Repair
We service and repair all major brands sold in the UAE market, whether or not we installed the original system — Hikvision, Dahua, UNV, IMOU, EZVIZ, and most generic PoE camera kits sold through local shops. Older analog (CVI/TVI) systems and legacy DVRs are also within scope; we carry adapters and legacy connectors that most repair techs don't stock.
Maintenance Tips to Avoid Repeat Faults
Most of the faults on this page are preventable with basic seasonal maintenance:
- Clean camera lenses and housings every 2-3 months, more often near the coast or construction sites.
- Check NVR storage and overwrite settings quarterly so old footage clears automatically instead of the drive filling up.
- Inspect exterior cable runs before and after summer — UV and heat degrade cheap cable jackets over a few years.
- Consider an annual maintenance contract if you've had more than one repair call in the past year — it's usually cheaper than paying per callout.
For diagnosing false alerts or general troubleshooting before booking a repair visit, see our CCTV night-vision troubleshooting guide or false alarm reduction guide — many issues are a quick settings fix.

Minor faults typically cost AED 100-250. Camera or NVR replacement ranges AED 300-1,200 depending on the part.
Most repair requests receive a same-day or next-day response. Call or WhatsApp +971 54 438 9066.
Yes — we repair CCTV systems regardless of who installed them originally.
Heat, dust, and coastal humidity are the main causes — they stress power supplies, cloud lenses, and corrode connectors faster than in milder climates.
Check power/network cables, NVR storage, and clean the lens first. If the fault continues, it usually needs a technician.
Yes — replaced parts carry manufacturer warranty, and our labor is guaranteed against the same fault recurring.
Yes, we cover villas, apartments, offices, warehouses, and retail premises across Abu Dhabi and Al Ain.
