PoE Surveillance Cameras with Motorized Zoom
When should you use a zoom lens?
We recommend cameras with a zoom lens when your target location is 60 feet or further from the camera. If you target location is less that 60 feet from the camera, you're safe to use use a 2.8mm or 3.6mm wide angle lens. These lens cover a lot of ground up close and our 3K and 4K cameras produce the clarity needed to ID individuals 60 feet away.
What is digital zoom?
Digital Zoom refers to zooming into an image by focusing on a specific group of pixels. The more pixels a camera has the farther you can digitally zoom without the image losing quality. Digital zoom is possible with any digital video feed (live or recorded) but the clarity will depend on the resolution of the camera producing the video feed. All of the cameras and video recorders that we offer support live and recorded digital zoom.
What is optical zoom?
Optical Zoom is a physical function of the lens used in the camera. Lens options include manual zoom and motorized zoom lenses. Unlike digital zoom, optical zoom does not degrade the clarity as you zoom in as the lens is optically adjusting the field of view, similar to a photographer's lens.
The video below provides examples of both optical and digital zoom. First, you optically zoom or adjust the lens to view the target location. Then you can use digital zoom at any time to zoom into the view for more detail.
