Security Systems Repair in Baku
Security system repair in Baku — circuit board repair for DVR/NVR, IP camera power supplies, fire panels, access control, turnstiles and door entry systems: unit will not start, does not see the disk, burnt PoE port.
Order
Send the make and model and describe the fault briefly. A video helps most — film the fault. Clear photos of the board help too.
Electronics repair for security and smart home systems: DVR/NVR mainboards, IP camera power supplies and PoE, fire alarm panels, KNX/Zigbee controllers, access control, turnstiles and barriers, and door entry systems. Component-level circuit board repair.
How we work
Not every device can be repaired
Sometimes restoration is not possible: the chip is discontinued and no spare can be sourced, no donor board is available, the board is severely damaged by fire or liquid, or earlier repair attempts have left it beyond recovery. In such cases we explain the situation plainly and, where possible, suggest an alternative.
In a security system the fault is often not in one device but in the power line: a shorted PoE port, a burnt camera power supply, a panel that cannot see a zone. So we begin diagnostics at the system's power.
We work on DVR and NVR mainboards, IP camera power supplies, fire alarm panels, KNX/Zigbee controllers, access control units, turnstile and barrier drives, and door entry and video intercom boards — circuit board repair throughout, not whole-device replacement. The case we see most: the recorder starts but does not see the disk.
For outdoor equipment there is an additional risk: surges arriving via lightning and the cable run. The hit lands first on the PoE port and the power supply, and those are usually restorable. While restoring the system we also check the protection stage so the same damage does not repeat on the next surge.
Devices we repair
Common faults we repair
- The DVR / NVR will not start or does not see the disk
- A short on the IP camera PoE port
- The camera power supply has burnt out
- A zone fault on the fire alarm panel
- The access control unit will not read cards
- The turnstile or barrier motor drive is dead
- The door entry system shows no picture
- The recorder does not appear on the network
- The system will not start after a lightning strike
- The KNX / Zigbee controller does not respond
- A leaking battery in the alarm panel
- The night vision (IR) illumination does not light
Typical causes of failure
- A short on the PoE port or the camera line
- A burnt power supply (the most common cause)
- A lightning surge reaching outdoor cameras and cable runs
- An open or shorted zone circuit on the fire panel
- A failed SATA controller in the recorder
- Damage to the board from a leaking battery
- Corrosion inside an outdoor enclosure from moisture and condensation
- A burnt power stage after a mains voltage surge

How the repair works
- 01
Enquiry and first contact
Tell us about the fault on WhatsApp or Telegram. We review what you send and let you know whether the device fits the work we take on.
- 02
Acceptance and diagnostics
If we can take the device on, we confirm it in advance — do not ship it before you have our confirmation. Once it reaches the lab, diagnostics are completed within 48 hours (two working days).
- 03
Estimate and approval
You receive a report covering the cause of the fault, the estimated cost, spare-part availability and the timeline. Work begins only after you approve it.
- 04
Testing and handover
After the repair the device runs a minimum 24-hour load test. Once it proves stable in normal operation, we report the result and hand it over.
Diagnostics and pricing
Diagnostics is paid work — 10–50 AZN depending on the complexity of the board. If you have us carry out the repair, that amount is deducted from the final price. An exact repair price is given only after diagnostics and is agreed with you before any work starts.

Request a repair
Message us on WhatsApp or Telegram with the BRAND and MODEL of the device and describe the fault in as much detail as you can. A VIDEO helps most: record the fault and explain in your own words what happens. Also send clear photos of the device and, if accessible, of the circuit board from several angles. The more detail you provide, the faster and more accurate our answer.
