7.4.2.3 Blind Detection
Blind Detection Enable
is used to analyse camera
inputs for blind images. By default, this is disabled. Blind
detection occurs when a camera is obstructed by a large
object or deliberately. It is mostly used to tackle acts of
vandalism.
Note: Blind detection is not recommended when using
cameras with infrared illumination.
Alarm Type
can either be alarm or event. Alarms are
reported to the Centre Server (depending on MDR model).
Events are stored but do not get reported to the Centre
Server.
For Alarm Link Setup details refer to 7.4.1 General.
Channel
is used to choose which channels you would like
the alarms to be triggered from. The options are 1 to 6 (4CH)
and 1 to 16 (8CH).
Sensitivity
has three options; High, Middle and Low.
Blind Detection Alarm Figure 101
Duration Time
specifies different lengths of time which
allow for longer/shorter alarm durations. If the alarm duration
is set to 30 seconds and a short 2 seconds alarm occurs, this
would be treated as a 30 second alarm. Can be set between 0
to 255 seconds. By default, this is 5 seconds.
Delay Time
refers to how long the blind image must be
detected for. This is to avoid false alarms. By default, this is
set to 5 seconds. Can be set between 0 to 255 seconds.
Alarm Off-Delay
is a period in which rapid
activations/deactivations can occur, which must be ignored.
By default, this is 10 seconds.

7.4.3.1 G-Force
G-Force Enable
is
used to analyse the MDR’s g-force
values. By default, this is disabled.
Alarm Type
can either be alarm or event. Alarms are
reported to the Centre Server (depending on MDR model).
Events are stored but do not get reported to the Centre Server.
For Alarm Link Setup details refer to 7.4.1 General.
Calibrate
internal or external G-sensor requires calibration
before use. Once the unit is installed (on level horizontal
ground) with the vehicle stationary (no vibrations/engine off)
click the calibrate button. This will zero all three axes: X, Y and
Z. Travelling forward with the MDR handle indicating the front
and the connectors on the back indicating the rear; Y
represents left/right; Z represents up/down.
G-Force Alarm Figure 103
Threshold Value
refers to the G values for which it will be
considered an alarm. This must be tested and determined for
your specific vehicle.
Alarm Off-Delay
is a period in which rapid
activations/deactivations can occur, which must be ignored. By
default, this is 10 seconds.
Note: G-Sensor values are digitally sampled and only provide
an average indication of the shock data.
