Camera blinking: causes and what to do?

November 8
2019

A video surveillance system is one of the most valuable means of protecting a business. If devices are not working properly, such as when a security camera flickers at night, finding the cause and fixing it quickly is important to protect the facility, equipment, and employees. Here are just a few of the common problems that can cause the camera image to flicker at night.

Nutrition problems

As is the case with most equipment, loss or lack of power will result in problems with the performance of the video surveillance system. If flickering images are observed when viewing the camera feed at night, then the first thing to check is the power source.

IP security cameras use infrared light to capture images in low light conditions. If the cameras are low on battery power, the IR light does not receive enough power to work properly. It’s also important to check the input power to make sure the equipment is running on a dedicated power source and not using a power splitter, which can reduce the amount of power supplied to the cameras.

Changing lighting conditions

Proper lighting is a paramount element in a camera’s ability to capture a consistent image. At night, headlights and lanterns are more likely to compromise the ability of a CCTV system to produce a clear image.

Because outdoor night vision cameras use infrared technology to capture high resolution images in low light conditions, headlights may occasionally flicker as the camera automatically adjusts from infrared to normal light to capture an image. Review CCTV footage to determine when devices are flickering the most. If changing lighting conditions are causing problems, adjusting the angle of the cameras or moving them to areas less affected by car headlights is a relatively quick and inexpensive fix.

Damaged connections or cables

Another problem that contributes to camera flickering is related to damaged connections or cables. Damaged hardware can cause power and communication problems, resulting in reduced image quality.

Check all connections to the camera for loose wires or cables that have been exposed to the weather. Exposed wires and cables are quickly corroded or otherwise damaged. We recommend that all external connections be properly installed in a weatherproof location to prevent damage to the elements. Any problematic connections or cables should be replaced immediately to prevent further damage to the security camera.

Outdated or faulty equipment

Let’s be honest. The older the video surveillance equipment, the higher the chance of problems. If you have problems with the new solution, you may have purchased faulty products. Therefore, to purchase a quality product, you should contact a trusted security store.

All CCTV cameras have a limited lifespan, and once a piece of equipment has reached the end of its useful life, there is little that can be done but to replace it. Once you’ve made sure your devices are getting enough power, and cables and connections are intact, you’ll probably start buying new cameras, a replacement switch, or a DVR. If the inventory provides a spare camera that functions properly, you can use it to confirm the “diagnosis” before buying a new complex.

If new equipment does not work, contact the manufacturer or installer for technical support and return instructions. Well-known manufacturers such as Hikvision and Dahua offer a warranty that covers defective equipment, including a refund of the purchase price or replacement of devices within a set period of time.

How to fix image flickering when using CCTV cameras?

Skip to content

  • View Larger Image

Often during the operation of the video surveillance system, the image from the cameras is of poor quality. It can be image blur, monochrome, noise, flicker.

The last of the above problems is quite difficult to deal with because the flickering may appear intermittently or even randomly.

What’s more, troubleshooting a security camera with an image that flickers or jumps requires patience. There are many factors that can cause this problem. In this article, we will summarize the most common causes and solutions to problems related to video flickering in a security camera.

There are several factors that can cause the video image to flicker. In most cases, this is due to poor lighting conditions in the camera’s field of view. It happens that due to ordinary street or indoor lighting bulbs operating at a certain frequency, the image from the camera starts to flicker.

Sometimes flickering occurs when the camera’s power supply is insufficient. In this case, the power supply or PoE switch does not provide the necessary parameters for the camera to work. Therefore, often the problem of flickering occurs only at night, because. that’s when the cameras need more power to run the IR LEDs used to illuminate the surveillance area.

The power frequency supplied to the camera may also be incompatible, causing flickering. Another problem occurs due to incorrect NVR / DVR settings, which can also cause cameras to flicker under certain conditions.

In some cases, video flickering is caused by interference due to improper installation, faulty equipment or power supplies, or poor environmental conditions. Below, we offer solutions for every problem that can cause your CCTV camera to flicker.

1. Power problems

A power outage or lack of power can cause performance problems with your surveillance system. This is especially true if the cameras flicker at night. IR LEDs turn on when it gets dark and need more power. If the power supply does not provide the required power, the security cameras will constantly flash or show ticking lines.

Check the power supply to make sure the cameras are getting enough power. If you are using IP cameras, please make sure the PoE switch can support all your cameras at the same time. If you are using security cameras that run on batteries, double check if there is a low battery issue.

2. Changing lighting conditions

If your security camera only flickers at night, make sure it is pointed away from electrical light sources. Frequent changes in lighting conditions, such as a sudden increase or decrease in light due to passing vehicles, can also cause the video image to flicker for a few seconds while the camera adjusts its IR LEDs.

If changing lighting conditions are causing the flickering problem, the cameras should be angled or moved to a location where they are less affected by the variable light in the frame.

2. Damaged cables or connections.

Damaged cables and connections can cause power and data problems resulting in a flickering problem. Check all connections to your cameras for missing or bad connections. Exposed wires and cables are susceptible to corrosion and other influences, so try to hide them underground or place them in sealed corrugated hoses.

The flickering problem can also occur if you use cables that are longer than the standard length for this type of camera.

If your security camera has an analog output or if you are using very long cables, make sure the cables are properly installed and grounded.

3. Electrical frequency

A camera intended for the US market but sold in Russia may have an electrical frequency specified for US markets. You need to take this into account. So, in the USA, power is used 110-120 V with a frequency of about 60 Hz. In Europe and many other countries around the world, 220-240V at 50Hz is used.

To set the frequency, your recorder, PoE switch, or composite power supply has a small switch that allows you to select the frequency. In addition, the frequency can be changed in the camera settings program. For example, below are the frequency settings of Dahua IP camera.

4. Using the Anti-Flicker function.

Many DVRs have an anti-flicker feature that you can turn on and try to fix the problem. If it is not enabled, and your image is flickering, try turning it on. If it’s on and yours is flickering, try turning it off. This feature is usually found in the picture settings section of the recorder/camera. If you cannot find it, read the manual or contact the manufacturer.

5. Video outputs

If your camera is connected to equipment with additional video outputs, make sure all video outputs are properly terminated.

6. NTSC and PAL

NTSC and PAL are two different video encoding systems still used in analog (HD) security cameras. Both of these protocols operate at different resolutions and frame rates and are designed for different regions of the world. For example, NTSC is used in the US, PAL is used in Europe.

Currently, most devices can play video in both formats. PAL or NTSC cameras (or recorders) will work anywhere as long as they are paired with cameras that use the same format. If you are using a security camera that does not support both of them, you may end up with flickering video and huge scrollbars on your screen. Enter the camera or recorder settings and set the correct video format.

7. Update the firmware to the latest version.

In some cases, especially if the flickering problem is due to software bugs, updating the firmware on your IP cameras, DVRs or NVRs can fix the problem. Make sure you have the latest firmware installed.

8. Aging or defective equipment.

The older your security camera, the more likely it is to have problems. All CCTV systems have a limited lifespan and if yours has reached the end there is little you can do but replace the equipment. If you have verified that the cameras are getting enough power and that the cables and connections are intact, then the problem is most likely with the outdated cameras and DVR.
