New Daisy Chain IP Cameras (Vivotek)

Author: Ethan Ace, Published on Dec 22, 2014

Surveillance cameras have traditionally all required home run cabling, with each connected to a dedicated network switch or DVR port.

Now, Vivotek has added PoE extension to select cameras (aka, daisy chaining) with the aim of reducing cabling, infrastructure, and overall cost.

The question is: Do these cameras make sense in the field? In this note we break down the capabilities of this new line, features, pricing, potential applications where it may make sense, and potential future impact.
