Camera with Manual Varifocal Lens

The ability to manually adjust the lens is especially valuable in surveillance systems where real-time monitoring may require changes in the field of view. By providing adjustable zoom levels, varifocal cameras allow you to change the field of view and zoom in or out as needed and capture fine details of distant objects. However, manual adjustment of focal length is very time-consuming and even challenging to achieve the desired precision and accuracy. You need to have someone check on the monitor while you adjust the camera lens and let you know when it’s in focus or you need to view the camera on your smartphone (if applicable) or computer. Therefore, the lens adjustment tool can be quite useful in on-site installation to calibrate your lens in real time and get the image in focus.
