Illustrative image of CCTV system inspection and maintenance.
A CCTV system is useful only when cameras capture clear footage, the recorder stores it correctly and authorised users can access the system. Regular inspection helps identify developing faults before they become security gaps.
Lock and Secure Systems supports existing CCTV installations with fault identification, practical repair recommendations and maintenance checks. Whether one camera is offline or the complete recording system needs attention, a systematic inspection helps locate the actual cause.
Support for common CCTV camera, recording, power, network and system-performance problems. The exact repair depends on equipment condition, model compatibility and fault diagnosis.
Inspection of indoor and outdoor cameras with issues such as no picture, intermittent video, blurred images, flickering, colour problems, poor focus, moisture ingress or physical damage.
Support for Digital Video Recorders used with compatible analogue and HD-over-coax CCTV systems. Checks include channel status, video input, recording settings, playback and output connections.
Network Video Recorder and IP camera checks for offline channels, IP conflicts, network disconnections, PoE issues, stream problems and recording interruptions.
Inspection of coaxial, UTP/Cat5e/Cat6, power and patch cabling. Damaged cable sections, loose terminations and faulty connectors can cause unstable or missing video.
Diagnosis of camera power adapters, centralised power supplies, DC distribution, PoE switches and power connections. Correct voltage and device compatibility are checked before replacement.
Checks for HDD not detected, recording stopped, storage errors, overwrite settings, missing footage and playback failure. Storage replacement is subject to recorder compatibility.
Investigation of dark night footage, IR illumination problems, glare, reflections, overexposure, foggy images and poor visibility caused by dirt or unsuitable camera positioning.
Help with authorised remote viewing when the CCTV recorder or IP camera is not visible on a phone or computer. Network, app, account and device settings are reviewed.
Scheduled checks to help maintain system reliability, identify wear and keep cameras, recorders and connections in good operating condition.
Repair and maintenance may involve the following CCTV equipment and accessories. Availability, compatibility and replacement options depend on the installed system and exact model.
Inspection of HD-TVI, HD-CVI, AHD and other compatible analogue camera systems. Checks can include video signal, image quality, connectors, power and DVR channel compatibility.
Network camera checks covering IP addressing, network connectivity, video streams, PoE power, image settings and compatibility with the NVR or VMS in use.

Tell us what you see on the monitor or mobile app. The visible symptom is a starting point; the actual cause is confirmed after checking the camera, recorder, power and network path.
Possible causes include power loss, damaged cable, loose connector, camera fault or recorder channel issue.
May relate to unstable power, network interruption, IP conflict, PoE port or wireless signal quality.
Could be caused by HDD errors, incorrect schedule, storage settings, recorder fault or camera channel status.
Storage health, recording configuration, date/time settings and recorder operation should be checked.
Lens dirt, dome marks, focus, camera movement, moisture or lighting conditions may affect image clarity.
IR illumination, camera settings, power, lens obstruction and nearby reflective surfaces may be involved.
Individual power feeds, connectors, cable runs, ports or camera hardware may need separate testing.
Power adapter, internal hardware, ventilation, storage or other recorder faults may need diagnosis.
Internet access, router settings, device status, app configuration or account permissions may need review.
We follow a practical inspection process to understand the fault, identify the required work and verify system operation after service.
Share your location, camera count, brand/model if known, and the issue you are experiencing. Photos of the DVR/NVR model label or monitor error can help with preliminary understanding.
Check camera condition, recorder status, power supply, cable routes, connectors, network links and the symptoms reported by the customer.
Identify likely fault areas and explain the repair, adjustment or replacement options. Additional work is discussed before it is undertaken.
Carry out the agreed service, which may include connection repair, cleaning, replacement of compatible parts, recorder configuration or network troubleshooting.
Where system access and equipment condition allow, verify camera live view, recording status, playback and relevant mobile/remote viewing functions.
Explain the work completed, any pending issues and practical maintenance recommendations for the CCTV installation.
A camera can appear to be working while the recorder has stopped saving footage or the hard disk is reporting errors. Preventive maintenance checks help you detect these issues earlier and keep the surveillance system ready for everyday use.
Illustrative image: camera condition and connection inspection.
For properties with multiple cameras or critical surveillance requirements, a planned maintenance arrangement can help organise periodic system checks and service visits.
Scheduled inspection based on the size and condition of the installation. A visit may include camera cleaning, visible cable and connector checks, recorder status, HDD status, recording and playback verification.
When a fault is reported, the affected camera or component can be inspected and the required corrective work assessed. Response time and service availability are confirmed at booking.
A maintenance contract can define the number of visits, covered devices, response arrangements, labour inclusions and exclusions. Replacement cameras, hard disks, adapters, cables, accidental damage, civil work and major upgrades may be chargeable separately unless expressly included in the agreement.
Contact us to discuss a maintenance plan for your home, business, apartment or institution.

Yes, no-video issues can be inspected. Possible causes include power failure, damaged cable, loose connector, camera malfunction or a DVR/NVR channel fault. The actual cause is determined after checking the system.
An offline camera may have a power, cable, network, PoE, IP configuration or hardware issue. For Wi-Fi cameras, signal strength and router connectivity may also be relevant.
Recording may stop because the hard disk is faulty or not detected, storage settings are incorrect, the recording schedule is disabled, a channel is offline or the recorder has a fault. HDD and recorder status should be checked.
We can inspect compatible DVR, XVR and NVR installations and troubleshoot common recording, display, channel, storage, configuration and network issues. Whether a recorder can be repaired or needs replacement depends on its model and condition.
Hard disk detection and recording problems can be checked. If replacement is required, the correct capacity, interface and compatibility must be confirmed for the recorder. Existing footage recovery is not guaranteed and should be discussed before any storage work.
We can check the recorder or camera network connection, app configuration and authorised device access. Remote viewing depends on internet connectivity, supported apps, account access and the equipment model.
We can assess compatible systems from brands including Hikvision, CP PLUS, Dahua, Trueview, Honeywell, Hi-Focus and TP-Link networking products. Support depends on model, firmware, parts availability and system compatibility.
We can assess supported HD analogue, IP/network, dome, bullet, turret, PTZ and Wi-Fi camera systems. Some proprietary, discontinued or physically damaged models may require replacement rather than repair.
Common causes include a dirty lens or dome cover, incorrect focus, camera movement, moisture, poor lighting, glare or a damaged camera. Cleaning and image checks can help identify the issue.
Night vision problems may be related to IR illumination, power supply, lens obstruction, camera settings, reflections or the distance and lighting of the monitored area. A camera inspection can help isolate the cause.
There is no single schedule for every property. Dust, rain exposure, operating conditions, camera count and the importance of the premises affect maintenance frequency. Periodic checks should include camera condition, recording, playback, storage, power and connections.
Ask us about planned CCTV maintenance arrangements. The number of visits, covered devices, breakdown support, labour, replacement parts and exclusions should be clearly defined in the agreed scope.
Existing installations from other providers can be assessed, subject to equipment condition, access permissions, model compatibility and availability of parts or credentials needed for service.
Compatibility depends on camera technology, video standard, resolution, connector type, network protocol and recorder support. The camera and recorder model numbers should be checked before purchasing a replacement recorder.
Footage recovery depends on the nature of the disk failure, whether data has been overwritten and the condition of the storage media. Recovery cannot be guaranteed. Avoid formatting or repeatedly attempting repairs if important footage may be present.
Repair cost depends on the fault, number of cameras, site location, equipment model, labour involved and whether parts or cables need replacement. Contact us with the issue and system details for an estimate after assessment. No fixed price is quoted on this page.
Share your area in Kozhikode, camera count, brand/model if known, whether the system uses DVR or NVR, the issue shown on screen and a convenient contact time. A photo of the recorder label or error message can be useful. Do not send passwords or sensitive access credentials in an open message.
Availability depends on technician schedules, location and the nature of the fault. Call the service number to check the earliest available appointment; same-day service is not guaranteed.
