If your CCTV camera has an analog output, or if you are using particularly long cables, make sure that the cables are correctly routed, and ensure that they are correctly grounded. ![]() The flickering issue may show up if you’re using long cables, beyond the lengths supported by your cameras. Check all of the connections running to your cameras for loose wires or wires that have been exposed to the elements.Įxposed wires and cables quickly become corroded or otherwise damaged. Damaged cables or connectionsĭamaged cables and connections can cause power issues and data transmission issues that lead to the flickering problem. If changing lighting conditions are the cause of your image flicker issues, adjusting the angle of your cameras or repositioning them to areas that are less directly exposed to oncoming headlights is a relatively quick and inexpensive solution. Sudden changes in lighting conditions, such as sudden increases and decreases in lighting due to cars passing by, may also cause the image to flicker for a few seconds, while the camera is adjusting its IR LEDs. If your CCTV camera flickers only when it’s dark, make sure that it’s pointing away from electrical light sources. If you’re using security cameras that run on batteries, double-check if there is a batter low issue. If you’re using IP cameras, ensure that the PoE switch is able to support all your cameras simultaneously. If the power supply fails to provide the required power, the security cameras will flicker constantly or show rolling lines.Ĭheck the power source and make sure the cameras are getting a sufficient power supply. The IR LEDs turn on when it gets dark and they need more power. This is the case especially if the cameras flicker during nighttime. Loss of power or not getting enough power can cause performance issues for your security camera system. Security camera image flickering: causes and solutions 1. Below we offer solutions and tips for each problem that may cause the security camera to flicker. In some cases, CCTV video flickering is caused by interference, either due to incorrect installation, malfunctioning equipment or power supplies, or bad ambient conditions. Or the settings on the NVR/DVR are incorrect which may trigger the cameras to flicker under certain conditions. For instance, if you’re in the USA you’re dealing with 60hz electrical power (and not 50hz which is the case for the rest of the world). The frequency of power being sent to the camera can be incompatible and also cause flickering. Often we see the flicker problem occur only at night time because this is when the cameras demand more power to support their IR LED lights used to illuminate the area under surveillance. This is the condition where your cameras need more power than your power supply can deliver a DC power supply, or PoE switch ( for IP cameras), or on recorders with a built-in PoE switch. Insufficient power is another possible cause. Certain light bulbs can operate at a frequency that will cause the camera monitoring it to flicker. In many cases, cameras flicker due to the lighting conditions. There are multiple factors that may cause a CCTV security camera to flicker. In this article, we’ve summed up the most common causes and solutions for security camera image flickering issues. There are a lot of factors that can cause this issue. Moreover, troubleshooting a security camera with an image that is flickering, rolling, or jumping takes patience. When your security camera’s video feed is flickering at night (or day), finding the cause and fixing it quickly is important to protect your house, property, or workplace.įlickering in CCTV security systems may be difficult to deal with because it may occur intermittently or randomly. The picture will degrade and if an incident happens you won’t be able to catch the whole action smoothly because the security camera was flickering the whole time. A security camera that has a flickering image will compromise the reliability of your security system. ![]()
