CCTV Camera Diagnostic Maintenance

I need an experienced technician to carry out full system diagnostics and troubleshooting on my existing CCTV setup. The task focuses purely on maintenance—no repairs or upgrades are required—so I’m expecting a systematic health-check that pinpoints any performance issues, connection faults, or software conflicts within the cameras, DVR/NVR, cabling, and network.

Here’s what I’m hoping to receive:
• A thorough diagnostic report detailing detected faults, weak points, or configuration errors
• Step-by-step recommendations to restore optimal performance, including any necessary firmware or software tweaks
• Confirmation that live view, recording, and playback functions operate smoothly once adjustments are made

All work must be completed on-site, with minimal downtime for the surveillance system. Please bring the necessary testing gear (multimeter, cable tester, laptop with CCTV analysis tools, etc.) and be comfortable working with common brands and protocols such as ONVIF.

If this sounds like your area of expertise, let me know your preferred timing and any information you need before arrival so we can keep the maintenance session efficient.
