Some users set up their home surveillance system by connecting the cameras to multiple PoE switches before connecting it to the NVR or other network storage like NAS. The loose connection between BNC connector and security cameras or H.264 DVRīNC connector, which is commonly used on thin Ethernet network cables and network cards to transmit signals, however, unexpectedly and frequently, explains the constant signal loss and video loss on PoE home surveillance cameras or H.264 DVR.Insufficient bandwidth via PoE switch or NVR.WiFi signal interruption & interference.Too many barriers between your camera & WiFi router.Long distances between wireless security cameras and home routers.Here are common reasons for network-induced video loss: Video loss or weak video signal among WiFi security cameras and systems could be caused by unstable network connections, weak WiFi connection or low internet bandwidth. Video Loss Reason 3: Weak WiFi Connection or Low Bandwidth UPS (Uninterruptible Power Supplies) units will ensure power supply for all cameras when there is a power outage, mitigating concerns for camera power-off.īesides, if it’s hard not to mount your camera to anything other than a metal/conductive surface, add a block of wood in between. To resolve such issue, try using power surge protectors or lightning surge protectors to protect your CCTV cameras from a lightning strike. Strong electrical currents interference from nearby electrical equipment.Mounting security camera to a metal/conductive surface.Here are some common reasons for power spike & interference:
It is likely to cause sudden video loss on security cameras, all CCTV cameras black screen, a camera with the electrified surface, the camera with a vertical/horizontal line, or serious damage to the camera circuit board or other components. Video Loss Reason 2: Power Spike & InterferenceĪnother horrendous hazard is power spike. If you are using battery-powered security cameras, for instance, Reolink Argus 3 Pro and Reolink Go Plus, make sure the battery is not dead or charged either via power adapter or solar panel. If PoE switches or PoE injectors are necessary, make sure you choose PoE switches or injectors properly.īesides, try using shorter BNC or Ethernet cables to power surveillance cameras system and avoid using low-quality extension cables or extension cords. Switch ports to make sure the DVR/NVR port is providing power to the cameras.Ĭonnect the IP cameras directly to the NVR (if there is any) instead of via a PoE switch because the PoE switch could potentially not supply insufficient power to the IP cameras.Įspecially the PTZ IP cameras or night vision IR security cameras, which draw more electricity than those don't come with PTZ or night vision (click here to learn more about security camera power consumption). Loose cable connection, for example, between DVR/NVR with cameras, between CCTV cameras and monitor or screen, power adapter, or any possible loose connection in camera power supply could cause video loss.ĭouble-check all power connections, power splitters, cable connectors, and etc.

In general, the issue of “video loss” on CCTV security cameras or DVR/NVR, in many cases, comes down to several factors: insufficient power supply, unstable network, wiring problems, hardware (cameras, NVR/DVR or monitor) failures, inefficient camera software and IP address conflicts.
