![]() ![]() 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. Faulty power cables (old, damaged, degraded or cut).Cable is too long, or one cable is supplying too many cameras at once.Here are some common reasons for insufficient power supply to CCTV cameras: The insufficient power supply is, very often, the culprit of the video loss on one or all security cameras, CCTV video loss at night, video signal loss on screen, camera going black at night, or camera video flickering on and off. Video Loss Reason 1: Insufficient Power Supply Today we share some of the best practices to deal with security camera video loss. Many users tried and used different ways to solve the video loss but in no luck. Security Cameras Video Loss – Possible Reasons & Troubleshooting 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. We have heard many users complaining about video loss problems on Swann Pro series CCTV cameras, Night Owl cameras, Zmodo cameras, Lorex surveillance camera, Amcrest camera or other cameras, Qsee cameras or CCTV/IP cameras of other brands. I apologize for the long-winded post and would appreciate any insight, suggestions or answers you all may have.Yes, Tell Me More Why Does Camera Video Loss Happen I'm trying to find a cheap camera on ebay that will work with this system, but have no idea what will work, and asking the sellers is not helpful. What I know (after learning and research) is that these cameras are 550TVL with BNC connectors and that the box is h.264. My issue is that there is very little documentation on the technical details of these systems that I understand are "sub-par" in the wide world of CCTV. I determined that 3 of the 4 cameras were faulty by taking the one working camera and testing it at the other 3 cameras' locations where it functioned properly (eliminating possible line issues). The second system is a harbor freight box with 4 cameras (Bunker Hill item no. I am generally a computer guy, and have plunged head first into the world of surveillance. I was able to get a newer PC-based system online (and half of the total cameras) due to a blown PC power supply. The owner is very set on getting them working rather than upgrading. There are 4 separate systems there that were all not working. I just recently got roped into troubleshooting a spiderweb of broken surveillance systems at a place of business. ![]()
