How To Adjust The Focus On The Security Camera By Changing The Setting?
Before any correction step, cleans the lens and the camera with tissue and use any liquid glass cleaner to get the best result. Cleaning the lens resolves the issue in most cases. But, if it hasn’t, now you need to go to the next step. Most security cameras come with a manual setting, and by correcting the settings, you can get a crystal-clear image.
There is no rocket science behind the settings, but it is slightly tricky. Let’s discuss the correction settings of different types of security cameras.
Change the setting by adjusting the screw.
A screw is present at the bottom of the camera. With the help of an Allen wrench, you can change or rotate the screw and change the setting. You will notice the change in the picture (it will zoom in or zoom out) while twirling the screw.
- While rotating the screw, you will notice that FOV (field of view) increases or decreases. A larger FOV means the camera is covering a wide area. And a shorter FOV means the camera is covering the lesser region. You need to select the FOV which is giving the best picture quality.
- Fine adjustment is quite a sensitive setting. After getting the suitable FOV, move the screw slightly to get the fine adjustment.
Adjust The Focus Of A Fixed Lens Camera
A fixed lens camera comes with an automated setting. Manufacturers professionally set the distance between the lens and the camera image sensor. But if the fixed lens is not working effectively. It means that during the installation, you have affected the automated setting. So, you are getting a blurry image.
These kinds of situations are easy to correct and require a little effort. Gently rotate the fixed camera and monitor the image. Stop when you get a clear picture. This situation is rare because manufacturers carefully develop fixed cameras. But the condition is present in cheap cameras.
Adjust The Setting Of The Dome Camera
It is a modern dome-shaped camera. If your dome-shaped camera gives a fuzzy image, check its setting by following a few below-mentioned steps.
- Gently remove the foam
- Move the infrared LEDs to one side
- Connect the camera to monitor to observe the image
- Twist the lens until you get the fine focus
- After getting the required focus, replace the infrared LEDs and foam
- Clean the camera lens
Why Does My Camera Become A Blur During The Night?
The problem is quite common. The lens aperture is the main culprit behind this problem, during day time there is a lot of light. And so, the camera aperture captures a lot of light and gives a clear image, but at night when the sun goes off, the same aperture takes a lesser amount of light and gives the image blur.
This problem can be fixed by changing the camera F-number. Change the camera F-number, and adjust the setting so it can work with the minimum aperture and give a deep depth field blurring nothing. Unfortunately, many cheap cameras don’t have this setting. Therefore they provide blur images at night. So, it is recommended to buy a good quality camera to get a high picture quality.
