CCTV camera image flickering is dependent on various factors, including incorrect installation, power supply, environmental conditions, and more.
Another common cause is the problem of insufficient power supply to the camera, which is due to the wrong design and installation.
In this article, we will fully explain the reasons for image jumping in a CCTV camera, so stay with us until the end of this article:
In CCTV systems, image skipping can occur for two reasons.
- Hardware reasons: such as power supply, cable, video recorder.
- Software reasons: such as coding compatibility disorder.
-
Power Supply
The power supply may be one of the reasons for the jump in the picture. Therefore, you should use a suitable source of nutrition.
-
Magnetic field near the CCTV camera
The presence of magnetic fields, such as a magnet or anything else, may cause interference and cause the image to bounce.
-
Cable
Improper wiring and poor quality cable can also cause signal interference. Carefully inspect all cables and hotspots and ensure that the cameras are properly connected.
The longer the length of the cable or cable path, the more likely it is that the image will be disturbed and skipped. In case of jumping, check the cables to make sure that they are not torn or decayed.
-
BNC Slips
One of the reasons for image skipping can be related to the slips.
-
CCTV Camera Installation Location
The location of the camera installation is also important. For example, if the place where the camera is installed in a warm place, the probability of the image jumping in the CCTV camera is higher.
-
System Software Issues
Another factor that causes disruption is software issues. So search for the latest version on the manufacturer's website and make sure your cameras are up to date.
-
Voltage fluctuations
First, it is necessary to give a brief explanation about this.
Flickr is created when the input voltage to the CCTV camera is low, or when the current fluctuates, the image on the monitor is flickered or flickered. Flickr in the camera is a problem that interferes with the recording of images.
Electrical fluctuations, lack of use of standard cabling, placement of coaxial and network cables next to high-voltage power cables, use of non-standard central adapters, etc. are among the factors that can cause the problem of CCTV images jumping, noise, etc. Are. Also, lighting or electrical problems can be the cause of the CCTV image jumping.
-
Low FPS or camera frame rate
FPS refers to the number of frames that the camera captures per second.
If the camera's FPS is low, some seconds when an object is at high speed will not be recorded. So it is possible that the fragments of the previous image will be associated with the present image when moving at high speed. This problem causes the CCTV camera to have color retention in the image.
-
Weak power supply
Other factors include poor power supply.
This usually happens at night when IR LEDs are activated. In PoE cameras, you need to check the camera's distance from the PoE switch and the type of PoE switch. Additionally, PoE may not be able to power all cameras.
Typically, IP cameras should not be placed at a distance of more than 90 meters from the PoE switch.
-
Direct light radiation to the CCTV camera
If the camera is exposed to direct light or if light is shining on the camera from a polished surface, it may cause the image to bounce in the CCTV camera.
