The AXW-AVT are designed to allow connection of a standard AX Series audio video door station via the AXW-AVT, conditioning the signal for use with 3rd party transmission equipment (fiber optics, Ethernet, etc.) and converting it back via the AXW-AVR to a signal compatible with the AX series exchange unit. External video input/output is provided at both adaptors to allow 3rd party camera input, output to recording devices, etc. A motion detector or other activation device can be connected to the Sensor input to trigger door / camera activation (AXW-AVT only). The units also feature a relay output to trigger an external device, such as a DVR or video switcher local to either the AXWAVT or AXW-AVR whenever the audio and/or video is active. Alternatively, the AXW-AVT can be used to adapt an AX-series audio video door station to a standalone third party device (video server, network DVR, etc).
