If you own a CCTV camera then you must have seen CCTV feeds and videos. In some cases, your CCTV video may not be very clear and it may have horizontal lines on the monitor. These lines which are known as smear or blooming could make it very difficult for you to view the video. There are a lot of reasons which could be causing these horizontal lines in CCTV video and if you wish to resolve them you must know these reasons as well. Afterall, watching an important recording can be interrupted due to these lines. The following are some of the causes as well as solutions for horizontal lines in CCTV video:

1. Light source coming in way of camera

CAUSE: One of the main causes of horizontal lines in CCTV videos is light source coming in way of camera directly. If a light falls directly on the camera, then the video that comes to you or the feed transmitted may not be clear and may result in horizontal lines. What happens is that most security cameras are single chip CCD sensor ones. If these are faced with extra bright light then the pixels get overwhelmed and the horizontal lines that you see are basically electrical interference of light sensor.

SOLUTION: To solve this problem, reduce the amount of light or change its angle. One way to reduce the light is by using a dome camera which has a darkened shell.

  4. INQMEGA PTZ Camera Outdoor Surveillance Camera with Two Way Audio 

2. Try a different camera

CAUSE: Low quality CCTV camera

SOLUTION: If the problem continues or is not resolved, then you can also try a camera with WDR or Widen Dynamic Range such as an Effio Series DSP camera.  You can also try a CMOS sensor camera because such a device does not face the problem of horizontal lines. But it is important to keep in mind that even a CMOS sensor camera has a problem with too much direct light. This is so because extra light can burn out the pixels of the camera and will hence not let the camera produce a clear feed.

3. Problem with the power supply

CAUSE: In some cases, horizontal lines on the video feed of a CCTV camera suggest that there is a 60 Hz AC component in the video.  This means that the power supply received by it is improper and needs to be changed.

SOLUTION: To solve this issue, you can change the power supply as it may not be very well filtered.
