The main reasons for security camera picture problems
Have you ever wondered why your security camera flickers at night? What could be causing your security cameras to appear fuzzy? And why do some security cameras have poor image quality?
The reasons behind CCTV surveillance camera image issues, such as unclear images, no picture display, night vision problems, or green/pink screens, can actually vary. Here are the primary causes we have compiled.
- Dirty camera lens: A dirty camera lens can significantly impact the quality of the image captured. Dust, smudges, and fingerprints on the lens can cause blurring and reduce clarity.
- Long cable runs: Security cameras that are situated far away from the recording device may experience signal loss, resulting in poor picture quality.
- Varifocal zoom that cannot automatically focus: If a varifocal zoom lens cannot automatically focus, it can result in an unclear image. This can happen when the lens is adjusted, and the camera cannot automatically readjust to the new focus.
- Low camera resolution: Cameras with low resolutions can produce grainy or pixelated images, making it difficult to identify individuals or objects.
- Weak or unstable Wi-Fi signal for Wi-Fi cameras: Wi-Fi cameras rely on a stable internet connection to transmit data. If the signal is weak or unstable, it can result in poor image quality.
- Low image resolution on the monitor: Even if the camera captures high-resolution images, if the monitor does not support it, the image quality will still be poor.
- Incompatible video formats: If the camera’s video format is not compatible with the recording device, it can result in poor image quality.
- Problems with IR lights or sunshade: If the camera’s IR lights or sunshade are not working correctly, it can result in poor image quality, especially in low-light conditions.
- Incorrect camera position or location: A camera placed in the wrong position or location may not capture the intended area or may capture irrelevant information, resulting in poor image quality.
- Incorrect camera resolution or video stream: If the camera’s resolution or video stream is not set correctly, it can result in poor image quality.
- Lack of an infrared cut filter for night vision: Cameras without an infrared cut filter may produce washed-out or distorted images when used in low-light conditions.

1. If your security camera picture is not clear or appears blurry, here are some solutions that you can try:
Here are the solutions to fix your security IP camera video or images not clear or blurry at night:
- Check the lens of your security IP camera for any dirt, dust, spider webs, or other obstructions that may be causing cloudiness. Use a soft and clean cloth to clean the lens, avoiding harsh or aerosol cleaners that could damage it.
- Verify that the extension cable run of your security camera is within the proper range, as stated in the camera specifications. For wireless security cameras, make sure the camera is not too far from the router.
- If you have a varifocal security camera, ensure that you adjust the focus and zoom settings. Keep in mind that varifocal cameras require regular adjustment, and if the camera fails to focus, the images may appear blurry.

2. If your CCTV security cameras are not showing images, you can try the following quick fixes:
- Check if your security camera’s power supply is working correctly.
- Test your security camera on a different DVR/NVR port to see if the issue is with the port.
- Try swapping the input cables to determine if there is a problem with the cable.
- Confirm that the video formats supported by your security cameras and DVRs/NVRs are compatible.
3. If your CCTV security cameras display green or pink images, try these tried-and-tested tips to solve your color problems:
- Relocate the security camera to a different position to determine if the issue persists with that particular camera.
- Manually turn the IR lights on and off a few times to see if it resolves the problem.
- Power cycle the camera by disconnecting the power connection and then reconnecting it to see if it rectifies the issue.
4. If your security camera picture is too bright, you can try the following four solutions:
- Avoid pointing the security camera directly at a source of light, such as the sun or a spotlight.
- If your security camera has an adjustable sunshade, move it forward to block excess light.
- Adjust the brightness and contrast settings of the security camera to achieve better image quality.
- Try relocating your security camera to a different position to reduce the amount of light entering the camera.
Note: Avoid pointing the camera directly toward a glass window to prevent reflection and glare issues.
5. If your security camera video picture is too dark or unclear, try the following solutions to fix the issue:
- Adjust the brightness and contrast settings of your security camera to improve the image quality.
- Try changing the position or location of your security camera to get a better view of the area you want to monitor.
- If your security camera has an adjustable sunshade, slide it backward to let in more light and improve the picture quality.
Remember to test your camera after each adjustment to ensure that the changes have made a positive impact on the video quality.
6. Check your security camera system resolution or video stream
Ensure that you have set the correct resolution for your cameras. Cameras with a resolution of 720p or 960H may not capture clear images or videos. If you are using a 4-megapixel (1440p Super HD) security camera, make sure that the resolution or video stream is set to 2560×1440 or at least 1920×1080.
If you are using a monitor to view the videos, ensure that it has the standard resolutions that are compatible with your cameras.
7. Check NTSC or PAL
Double-check if your security camera is compatible with NTSC or PAL, which are two distinct video encoding systems with different resolutions and frame rates used in different countries and regions. If your camera is not compatible with one of these formats, you may experience a video screen with black lines that appear to shake in place. However, most security cameras can play videos in both formats, but it’s still important to read the specifications carefully before making a purchase.
8. Ensure your security camera has infrared cut filter for better night vision
Having a high-quality night vision capability is essential for security cameras. Without an IR cut filter, images captured at night can be blurry and unusable, especially for outdoor cameras. Additionally, certain ambient lighting in indoor environments can also cause image quality issues.

Ensure the proper functioning of the power supply for your CCTV security camera by checking for any ground loop issues or faulty power supplies. “Rolling lines” – horizontal or vertical lines that move across the screen – may indicate such problems. This applies to both wired (PoE) and wireless (WiFi) cameras.
10. Update to the latest firmware
To address issues such as image display problems and flickering, security camera manufacturers often release updated firmware versions that fix bugs. You can check the manufacturer’s website or the security camera company’s website for the latest firmware. It is important to ensure that you download the correct firmware for your specific camera model and follow the instructions carefully when updating it.
11. Restart the security camera
If your security camera is displaying poor image quality, such as showing a green or black screen, restarting the camera can often resolve the issue. While it may not be a guaranteed solution, restarting the camera is a quick and easy troubleshooting step worth trying. Give it a try and see if it helps resolve the problem.
12. Contact the security camera company support team
If you are experiencing image quality issues with your security camera, it is recommended to contact the company’s support team. Many security camera companies offer free technical support, and you can find their email or phone number on their official website. Be sure to provide a detailed explanation of your problem so that the support team can quickly understand your issue and provide appropriate solutions.
