The camera can be connected to an external microphone, speaker
and video monitor through the I/O connector.
NOTE: The camera only supports line level mono audio input and an
NTSC or PAL video output.
The video output signal is determined by the camera flicker control
setting. When the camera flicker control is set to 60 Hz, the video
output signal is NTSC. When the flicker control is set to 50 Hz, the
video output signal is PAL. Use the Avigilon Camera Installation Tool
to configure the camera's flicker control in the Image and Display
setup.
