Ask-4® #350 is a single zone audio monitoring system for direct connection to an PoE complaint IP camera or Video 
Server. This kit comes with a UL listed IF-PX which is a POE inline interface and a Verifact A Microphone. The IF-PX 
extracts power from an Ethernet line to supply power to remote microphones, Speaker/Microphones or other 12V 
devices. It has a terminal block to connect to the microphones (one-way audio) and speaker/microphones (two-way 
audio). The 3.5mm stereo audio output and input jacks are for direct connection to the audio inputs and outputs of an IP 
Camera. This unit also offers volume control for the audio output. Supports both Mode A and Mode B power options of 
IEEE802.3af

The Verifact   A is an omni-directional, low impedance, electret condenser microphone with built-in preamp for producing 
line level audio. It is housed in a high impact ABS dome designed for ceiling or wall mounting. Normal pick-up pattern is 
approximately 15’ from the microphone location, all direction or within 30’ diameter circle
