G. Adjusting the Camera Focus
The HNC300/HNC320W features an exchangeable CS-type lens that can be used for different applications as necessary.
It supports rotational focus control so the lens can be adjusted to focus under normal and stable conditions to maximize
the image quality of the camera.
To adjust the focus of the lens, you need to turn the lens slowly in either the clockwise or counterclockwise direction until
the desired image quality is reached. Do not over turn the lens in either of the directions, as it will be out of focus. Unless
you wish to replace the lens, do not unscrew the lens more than 1.0mm apart from the Fixed Lens Assembly.
Note :
You can further adjust the network camera’s image quality via the Web Configuration under System Administration -
