Image Contrast
YOYOCam supports five contrast levels to adjust the camera to the ambient conditions. Contrast
level 1 is softest and 5 is most contrasty. Default is 4.
Command:
#38#ContrastLevel#
Example:
#38#3#
Response:
Image contrast has been set to 3
Note: Check your image contrast setting in each different condition (e.g. daylight, night) to make sure
that the image is captured ok.
Wireless Sensors
You can add up to 15 external wireless sensors which operate on the 433MHz standard. When
YOYOCam is armed and a sensor is triggered, YOYOCam will emit a warning bleep and raise an
alarm by SMS only or SMS followed by MMS, according to the way the sensor is configured.
There are two alarm modes for wireless sensors:
Armed-Only Mode: sensor only triggers the alarm when the YOYOCam is armed. This mode
is good for door sensors and infrared sensors.
Always-On Mode: sensor will always trigger the alarm (even when YOYOCam is disarmed).
This mode is good for smoke detectors, gas detectors, panic buttons.
