Overview
An indoor 1.3MP vandal-resistant dome with a 2.8-10mm varifocal lens, so you can set the view from wide to tight at install. It's PoE-powered with an SD slot for backup recording and two-way audio through an external mic. There's no IR, and it's a discontinued 2011 model replaced by the WV-SFR310A - fine as a straight swap for one you already have, but I'd skip it for a new install.
