Motion Detection Defined
The motion detection determines whether the amount of motion in a target region
exceeds the desired threshold. If the motion rises above the threshold it will trigger
the motion detection.
 Sensitivity: When a sensitivity value is entered, the given value will determine
whether the pixel is considered to have motion activity. The higher the value
entered, the more that same motion sequence will be considered as motion
resulting in a triggered motion detection. In cases where there is little light, it is
suggested to reduce sensitivity in order to prevent overreaction to background
noise.
 Threshold: This value decides the percentage of pixels to be marked as “changed”
in order to trigger a motion event. A smaller threshold will result in the encoder
responding to movement by smaller objects or even natural background noise.
The default value is 10; increase to filter out smaller objects.
 Interval: The amount of time that must pass before another motion event can be
detected. This is used to prevent the encoder from generating too many motion
detection signals.
 Noisy Environments: The background noise will be greater and can cause non-
existent motion activity. In this case, lower the sensitivity level and reduce the
threshold.
 Object Size: Generally a smaller target region will be more accurate and sensitive
than a bigger region. It is best to cover the capture area with two or all three MD
regions rather than one large section covering the majority of the streaming
video.
3.3.7 OSD/Privacy Mask
To enable, click the “Enable” box. OSD, or On Screen Display, or Privacy Mask can be
selected. The privacy mask will place a color box over the desired area in order to
prevent the area from being seen on the encoder web browser video display. The
redacted display will also be presented on the video output when connected to a KBC
Decoder. When the OSD is selected, the format parameters must match the format
notice. At that point whatever is written into the “String” area will appear on the
video display. This text will not be displayed by the decoder video output.
3.3.8 SNMP Setting
Click to enable V1/V2 SNMP support or select SNMP V3 to support Version 3.
3.3.9 UPnP
Click to enable UPnP and enter the UPnP Friendly Name.
3.3.10 Bonjour
Click to enable Bonjour and enter Bonjour Friendly Name.
3.3.11 IP Address Filtering
The encoder can deny or allow certain IP addresses in order to filter network traffic
coming into the device. In “Allow” mode, the encoder will filter all IP addresses other
than the list of allowed IP addresses. All IP addresses that the encoder must listen
for must be listed manually. In “Block” mode, the user lists the IP addresses not
allowed and the encoder will allow all other IPs.
Note: Configuration of this option must be performed with care. If the IP address of
you computer is not listed in the “Allow” (or is listed in the “Block” list) you will
be denied access from the encoder web browser GUI. An incorrect configuration
may result in the need for a hard reset to factory default.
