Watch this video demo to see the motorized zoom lens of a 4K CCTV camera (4K-B2Z) controlled by a Viewtron security camera DVR. The 4K-B2Z camera has a 2.8-12mm motorized varifocal lens with auto focus. The camera’s motorized lens is controlled by the PTZ controls on the Viewtron DVR that the camera is connected to. The camera is hard wired to the DVR using RG59 coax cable.
Please note that these cameras use UTC, which stands for “Up the Coax”. It allows for the zoom commands to be send over the same coax cable as the video. There is no need to run additional cable. The above screenshot shows the PTZ controls on the DVR. The zoom in / zoom out buttons are the only ones applicable to this camera.

Installation
You can see how this camera is installed on the exterior of our building. The 4K-B2Z is the bullet camera on the right. You can see that we used one of our optional outdoor junction boxes, as we typically recommend for outdoor installations. The big camera on the left is a Viewtron auto-tracking PTZ camera.

2.8mm Lens Setting
Here is a snapshot with the lens zoomed out to the widest setting, the 2.8mm setting. I am standing 90 feet away from where the camera is installed.
12mm Lens Setting
This image was captured with the lens zoomed in to the 12mm setting.
Digital Zoom
In the above screenshot, I digitally zoomed in to see if I would be able to be identified at 90 feet way.
130 Feet Way – 12mm Lens Setting
This last image show me standing 130 feet away from where the camera is installed. The motorized zoom lens is set to the 12mm setting. Obviously people can not be identified at this distance but you can see activity very clearly.
