Camera Image Issues: This encompasses a wide range of problems, such as blurry images, poor night vision, no image at all, color distortion, and flickering. These problems can stem from faulty camera settings, damaged cabling, lens issues, or internal camera malfunctions.
DVR/NVR Problems: Digital Video Recorders (DVRs) and Network Video Recorders (NVRs) are the brains of your security system. Issues can include hard drive failures, network connectivity problems, software glitches, and hardware malfunctions. A failing hard drive, for example, can lead to lost recordings and system instability.
Power Supply Problems: Inadequate or faulty power supplies can cause intermittent operation or complete system failure. This is often overlooked but crucial for reliable operation.
Network Connectivity Issues: For IP cameras, network connectivity is paramount. Problems range from incorrect IP addresses and network configuration issues to faulty network cables and switches.
Software Glitches: Outdated firmware or software bugs can lead to unexpected behavior, performance degradation, and even complete system crashes. Regular firmware updates are essential.
Physical Damage: Environmental factors like extreme temperatures, moisture, and physical impact can damage cameras and recording devices. Proper housing and protection are crucial.

Before calling a professional, it's advisable to attempt basic troubleshooting steps. This can often identify and resolve minor issues quickly and efficiently:
Check Cables and Connections: Loose or damaged cables are a common culprit. Inspect all connections, ensuring they are secure and undamaged.
Verify Power Supply: Ensure the power supply is functioning correctly and providing the appropriate voltage. Check for blown fuses or damaged power cords.
Restart Devices: A simple power cycle of the camera, DVR/NVR, and network devices can often resolve temporary software glitches.
Check Network Settings: For IP cameras, verify the IP address, subnet mask, and gateway settings are correct and match your network configuration.
Review Event Logs: Both cameras and DVRs/NVRs typically maintain event logs that can provide clues about the nature of the problem.
