Swann CCTV cameras are some of the best security cameras available and are known for their high-quality images. But, one thing that many people don’t know is that there’s a chance that your camera could have a grainy picture.
In today’s article, I’m going to cover some of the most common issues and fixes for Swann Camera Grainy Pictures.
What Are The Most Common Causes Of Your Swann Cameras Grainy Picture?
There are a few things that can cause your CCTV to produce grainy or blurry pics.
Here are a few of these causes and what you can do to fix them.
The Security Camera’s Lens Could Be Out Of Focus
If you notice that the pictures on the screen are not as clear as they should be, it could mean that the lens is not focused. Try adjusting the focus by using the zoom in and zoom out buttons.
If the focus is not adjusted, the pictures will look grainy and blurry.
You can also adjust the focus by changing the angle of the camera’s lens.
A Dirty Lens
Another reason for blurry or grainy pictures is dirt on the lens. You can clean your camera lens by placing it under running water.
If you notice that the pictures are still blurry, try cleaning the lens again.
Defective Image Sensor
If the pictures that come out of your camera are blurry, it may be because the camera has a faulty image sensor. This sensor converts the light into a digital image. It can be replaced by an authorized service center.
Low-Resolution
Most high-definition security cameras have a resolution of 1080p or 720p. These high-resolution cameras will produce clearer images than lower-resolution cameras.
If you notice that the video from your camera is blurry or pixelated, it could mean that the video resolution is too low.
Try increasing the resolution by going into the menu and selecting ‘Display’.
Next, you will need to click on ‘Display settings’.
Here you are able to change the resolution of the camera to something higher.
Check The Dome Cover
If the image on the screen appears faded, it could be because the dome cover on your camera is not in good condition.
If the dome cover is damaged or worn out, this can make the images on the screen look grainy or blurry. In some cases, you can replace the dome cover by following the owner’s manual instructions.
Check For Loose video Connections
If you notice that the video from your camera is blurry, it could be because the video cables are loose. Loose connections can cause a blurry image on the screen.
To fix this, you will need to make sure the video cable connections are secure by just giving them a little push so that they are all the way in.
Why Are Security Cameras Dark And Grainy At Night-time?
The way CCTV cameras see in the dark down to the built-in infrared (IR) light source allows them to operate even when it is completely dark outside.
This IR light is emitted in a controlled and directional way by using a beam of light that is emitted from an LED bulb. The camera detects this IR light coming from the bulb and thus allows you to get a clear image of the area around it, even if it is completely dark outside.
It is not possible for a person to see the IR light because they are not able to see anything in the dark, but the security camera will still detect it and capture a clear picture of the area surrounding it.
If the night vision image that you see is blurry, the IR sensor may not be able to detect enough IR light.
This can be solved by changing the brightness of the IR light source. You will need to do this within the camera’s menu.
