5.1 Powering the Camera
The power consumption specification is: Standard voltage via Power over Ethernet (PoE) or 5 - 16 V via GPIO
interface, maximum 2.5 W (2 W BFLY-PGE-13E4).
Power can be provided over the Ethernet interface (PoE). To use PoE, you must also have a powered Ethernet card, a
powered Ethernet switch, or an Ethernet power injector.
Power can also be provided through the GPIO interface on the back of the case. For more information, see
Input/Output Control on page 27.
If both interfaces are connected, the camera always uses external power over the GPIO connector. If external power
is not connected, the camera uses PoE. The camera reboots when switching between power sources.
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)
below.
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.
• Acquisition Frame Rate and Current Frame Rate
• Image Data Format, Position, and Size
• Current Video Mode and Current Video Format
• Camera power
• Frame information
• Trigger Mode and Trigger Delay
• Imaging Parameters such as: Brightness, Auto Exposure, Shutter, Gain, White Balance, Sharpness, Hue,
Saturation, and Gamma
• Input/output controls such as: GPIO pin modes, GPIO strobe modes, GPIO PWM modes
