USER MANUAL
•
mdzonesize
‒ size of motion detection zones measured in number of
32x32 pixel blocks in each zone; All zones are squares of the same size
from 7x7 to 15x15 (valid values are 7 to 15 for MP1 and MP2 and 8 to 15
for AV3100 and MP3-DN)
•
mdlevelthreshold
‒ motion detection threshold that determines the
sensitivity to local inter-frame brightness changes (valid values are 2…31).
Lower settings may cause false motion detection due to noise. This
parameter corresponds to “Level” under “Motion Settings” in AV Video
System GUI.
•
mdsensitivity
‒ sensitivity of the motion detection to sudden overall
lighting changes. This allows preventing false triggering due to sudden
overall brightness change that triggers motion detection in a large number
of zones simultaneously. If more than this number of zones have motion it
is assumed that the change is due to lighting change and detected motion
is ignored; (recommended values are 40 for MP3-DN, 30 for MP2 and 20
for MP1). This parameter corresponds to “Limit” under “Motion Settings”
in AV Video System GUI.
•
mddetail
‒ allows controlling the size of detectable moving objects. The
value is the number of 32x32 sub-zones within each zone that should
contain motion for the entire zone to be considered to contain motion.
(valid values are 1 through square of
mdzonesize
). This parameter
corresponds to “Detail” under “Motion Settings” in MP Video System GUI.
•
mdprivasymask
‒ Privacy matrix. An 8-byte array, where each byte
corresponds to one row of motion detection zones. Each bit in a byte
enables motion detection in a corresponding zone, if set to ʻ1ʼ. Leftmost
zone is controlled by MSB, rightmost zone by LSB.
Example:
set?mdprivasymask=2a8f3d135b71ee04 results in the
following enabled zones relative to camera image:
01010100
11110001
10111100
11001000
11011010
10001110
01110111
00100000
•
mdresult
‒ Motion detection information returned by the camera; The
return value is “no motion” if motion has not been detected, otherwise the
motion detection information is returned in the following format:
