Powering the Camera
The power consumption specification is: 12-24 V, <2.5 W, via GPIO.
Power must be provided through the GPIO interface. For more information, see
Input/Output Control
. The required
input voltage is 12 - 24 V DC.
Point Grey sells a 12 V wall-mount power supply equipped with a HR25 8-pin GPIO wiring harness for connecting to the
camera. For more information, see the
miscellaneous product accessories page
on the Point Grey website.
The camera does not transmit images for the first 100 ms after power-up. The auto-exposure and auto-white balance
algorithms do not run while the camera is powered down. It may therefore take several (n) images to get a satisfactory
image, where n is undefined.
When the camera is power cycled (power disengaged then re-engaged), the camera reverts to its default factory
settings, or if applicable, the last saved memory channel. For more information, see
User Sets (Memory Channels)
.
5.2
User Sets (Memory Channels)
The camera can save and restore settings and imaging parameters via on-board user configuration sets, also known as
memory channels. This is useful for saving default power-up settings, such as gain, shutter, video format and frame rate,
and others that are different from the factory defaults.
User Set 0 (or Memory channel 0) stores the factory default settings that can always be restored. Two additional user
sets are provided for custom default settings. The camera initializes itself at power-up, or when explicitly reinitialized,
using the contents of the last saved user set. Attempting to save user settings to the (read-only) factory default user set
causes the camera to switch back to using the factory defaults during initialization.
The following camera settings are saved in user sets.
