The DF4920HD-DN is a 5-megapixel HD network camera built into a compact and lightweight box housing.

The camera provides real-time Full HD video (1080p/30) using the H.264 codec, currently, the most advanced standard for high-efficiency video compression and supports resolutions up to 5-megapixel.

Besides a comprehensive set of automatic and manual image optimization functions and many other setting options, it features automatic Day/Night operation supported by integrated ambient light sensing and a removable IR cut filter (ICR1)).

The built-in Remote Back Focus Control technology allows for a precise and easy remote focusing over the network.
With just one click, first the almost ideal focus range is recognized automatically (One-Push Autofocus), which then can be precisely adjusted by using manual fine-tuning, if needed, in order to always get perfect images with excellent sharpness.

In conjunction with the Digital Image Shift function, which provides for a subsequent digital fine alignment of the image section, a convenient and straightforward installation process of the camera is guaranteed.

Depending on the requirements, the camera can be conventionally supplied with 12V DC or conveniently operated via Power over Ethernet (PoE Class 0, IEEE 802.3af) which allows for an easy, quick and cost-effective cabling and commissioning.
