Arrival and Preparation.
Upon arriving at the client’s location in Tayud, Consolacion, Cebu, our team coordinated with the assigned personnel and prepared the necessary tools and equipment for the maintenance activity. Proper preparation is a crucial step in any technical service, as it ensures efficiency and minimizes downtime. We organized cleaning materials, diagnostic tools, and testing devices required for inspecting the CCTV NVR system. After confirming access to the equipment and verifying the work scope, the Preventive Maintenance Service officially started at exactly 1:16 PM.
Inspection of the NVR Unit.
The first step of the maintenance process was a thorough inspection of the Network Video Recorder (NVR). We examined the physical condition of the unit, checking for visible signs of wear, loose connections, or potential hardware issues. The power supply and indicator lights were reviewed to ensure stable operation. We also assessed the ventilation and placement of the device to confirm that it was not exposed to overheating risks, which can significantly affect performance and lifespan.
Checking Recording and Camera Connectivity.
A key component of the PMS was verifying the recording functionality of the system. We accessed the NVR interface to review live camera feeds and playback recordings. This allowed us to confirm that all connected cameras were transmitting video properly and that recordings were being stored without interruption.
In addition, we checked the camera connections and network cables to ensure secure and stable links between the cameras and the NVR. Any loose or improperly connected cables can result in video loss or recording gaps, so careful inspection was performed to maintain consistent monitoring coverage.
Cleaning and System Optimization.
Dust and debris can accumulate inside and around electronic equipment over time, potentially affecting performance. As part of the preventive maintenance process, we carefully cleaned the NVR unit and its ports. This included removing dust buildup and ensuring that connectors were free from obstruction. Proper cleaning helps prevent overheating, improves signal stability, and extends the overall lifespan of the device.
After cleaning, we conducted a final system check to confirm that the NVR was operating smoothly. The cameras displayed clear live footage, and playback tests verified accurate and continuous recording.
Conclusion.
The Preventive Maintenance Service at ROZ Laboratories, Inc. was successfully completed at 1:30 PM. After a comprehensive inspection, cleaning, and functionality check, the CCTV NVR system was confirmed to be operating properly. With the system now functioning reliably, the client can continue to depend on clear monitoring and secure recording, ensuring a safe and well-supervised environment within their facility.
