The
th power
command displays the current setting of the heating power.
:th power
50%
Note: the same LEDs are used for lighting and for heating, but the power assigned for heating may differ
from the power assigned for lighting.
5.5.3.4 Setting Temperature Thresholds
If the thermostat is enabled, the LEDs are turned on when the internal temperature falls down to the
lower threshold, and are turned off when the internal temperature rises up to the upper threshold.
The
th ton N
command sets the lower temperature threshold. The
N
is a signed integer value in
°C
.
:th ton 0
The
th toff N
command sets the upper temperature threshold.
:th ton 10
The commands
th ton
and
th toff
display the current settings for the temperature thresholds.
:th ton
+0'C
:th toff
+10'C
5.5.3.5 Saving Thermostat Settings
The
th save
command saves the current thermostat settings to the EEPROM.
:th save
OK
5.5.4 Preheat Control Command –
ph
The preheat is the feature that allows to delay the camera startup until the internal temperature reaches
the specified threshold. It allows the camera to avoid operating at the temperature which is out of the camera's
ratings.
Note: Preheat is not functional in the PoE chain configuration and should not be enabled.
5.5.4.1 Preheat Monitoring
The
ph
command displays the state of the preheat.
:ph
Preheat: ON Power=100% Temp=+18'C Heater: OFF
The first parameter (
ON
or
OFF
) shows whether the preheat feature is enabled or not.
The
Power=
parameter is the actual setting for the LEDs power used during the preheat.
The
Temp=
parameter is the internal temperature.
The last parameter displays the state of the heater (
ON
or
OFF
).
5.5.4.2 Enabling Preheat Feature
The
ph on
command enables the preheat feature, the
ph off
command disables it.
:ph on
:ph off
5.5.4.3 Setting Power for Preheat
The
ph power
N
command sets the power of the LEDs for the preheat in %.
:ph power 100
The
ph power
command displays the current setting of the preheat power.
:ph power
100%
Note: The preheat power can be set higher because the camera is off and does not consume power.
5.5.4.4 Setting Target Temperature
If the preheat is enabled, at the power up the camera is off and the Heater is on. When the internal
temperature reaches the target value, the heater is turned off and the camera is turned on.
