#1. Fix It When Your Security Camera Picture Is Not Clear or Blurry
Here are the solutions to fix your security IP camera video or images not clear or blurry at night:
- Check the security IP camera lens for dirt, dust, spiderwebs, etc. if it it cloudy. Clean the lens with a soft and clean cloth. Do not use harsh cleaners or aerosol cleaners that may harm the lens.
- Check your security camera specifications to make sure the extension cable run is in the proper range. If you are using a wireless security camera, make sure the camera is not too far from the router.
- For a varivocal security camera, you need to adjust the focus and zoom settings. Remember varifocal cameras require adjustment from time to time. If the security camera fails to focus, the images would be indistinct (you can try the solutions for cameras failing to focus).

#6. Check Your Security Camera System Resolution or the Video Stream
Make sure you've set the right resolutions for the cameras. A 720p or 960H camera may not capture clear images or videos. If you are using a 4-megapixel (1440p super HD) security camera, make sure the resolution or the video stream is set to 2560×1440 or at least 1920×1080.
If you use a monitor to see the videos, make sure it has the standard resolutions with your cameras.
#7. Check NTSC or PAL
NTSC and PAL are two completely different types of video encoding systems. They have different resolutions and frame rates, and different countries and areas would use different types. See more information about NTSC VS PAL. If you are using a security camera that cannot be compatible with one of them, you may get video screen covered with black lines that appear to be shaking in place.
Editor's Note: Most security cameras can play video in both formats. Anyway, you should read carefully before purchasing anything.
#8. Make Sure the Security Camera Has Infrared Cut Filter – the Night Vision
Not all security cameras have high quality night vision, and if your camera lacks an IR cut filter, it will cause your security camera blurry at night and you are not going to be able to use it outdoors.
Be aware that certain ambient lighting in an indoor environment can also cause the image quality problems. Buy a high quality night vision security camera.

#9. Check the Power Supply of the CCTV Security Camera
If you get ”rolling lines” – horizontal lines across your screen that will normally move from bottom to top, or vertical lines that move from one side of the screen to the other side – this can often be caused by a ground loop problem of the power supply or by the faulty power supplies. Make sure the power supply for your wired (PoE) or wireless (WiFi) security camera is working properly.
#10. Update to the Latest Firmware
Most manufacturers or security camera companies will provide new firmware regularly to fix bugs, including troubleshooting the camera picture issues like CCTV cameras not showing images and flickering problems.
Check the manufacturer's website or the security camera company website to see if there is newest firmware released for the security camera. Update your camera with the latest firmware.
Editor's Note: Follow the instructions carefully when you update the firmware. Make sure the firmware you download from the website is the correct one for your security camera.
