The Panasonic WV-SPN531A is a simple IP box security camera. It uses a 2MP sensor to capture at 1080p HD. Enhanced Wide Dynamic Range helps clear through difficult lighting scenarios, such as when unnatural office light clashes with natural sunlight coming through a window. A day/night IR cut-filter activates to produce great night-time vision. An SD Card Slot allows for onboard memory storage. This camera comes with two-way audio.
