Digital Noise Reduction (DNR): DNR is the process of removing noise from a signal. It compensates
for the low-light conditions, and corrects imperfections in the image by removing a large percentage
of the noises; it helps to deliver a cleaner signal, a more visually appealing image, and make it easier
to identify the objects.
Self-adaptive Protocol: The speed dome is compatible with PELCO-D, PELCO-P, PRIVATE-Code,
VICON and KALATEL-32 protocol, etc., and is capable of being self-adaptive to these protocols
without selecting protocol by DIP switch settings. You can also configure the protocol via OSD menu.
Manchester Code Self-test: The speed dome supports Manchester code self-test for fault diagnostic
while adopting Manchester protocol. You can enable the Manchester code diagnosis function by
setting the positions 4, 5 and 6 of DIP Switch SW2 to ON. The corresponding fault code will be
displayed on the screen (not available during park time).
