Video Proc-Amp for Motion Profile

For analog cameras and USB webcams, it is possible to maintain separate Video Proc-Amp

settings (the qualities of an incoming video signal, such as brightness, contrast, hue, saturation,

gamma, and sharpness) for each of the motion profiles 1-7. Using the camera's Timer page

this allows you to change these settings based on the time of day--at night you may wish to

turn off color processing and increase contrast, for example. Use the Save button to make a

snapshot of the current Proc-Amp settings for the selected profile. Use the Load button to

recall previously saved settings. A device's Proc-Amp settings may be accessed via the

Driver/Source button.

Some analog capture devices offer both a "preview" pin as well as a "capture" pin. By default,

Blue Iris uses the capture pin. If you receive an initialization error, please try using the Use

preview pin instead of capture pin option.

Your video hardware may provide additional property pages. To access these once the camera

is operational, right-click the video image and select from the "Hardware property pages"

submenu. If your capture card has a TV tuning capability, for example, this is where you will

find this option.

BT8x8 Compatibility

Blue Iris is compatible with virtually all of the inexpensive BT8x8-based 4-input capture cards

available today, and is able to use multiple input ports on those cards simultaneously. In order

to offer these cards so cheaply, manufacturers include a SINGLE BT8x8 video capture chip. It is

then up to the software to choose which input signal to use. In order to use them all

simultaneously, the software must "multiplex" the 4 signals into the BT8x8, and then de-

multiplex the captured video so that you may see each input independently.

On 32-bit Windows, the Conexant Universal BT8x8 driver has been found to work reliably with

these cards. Please install the Conexant Universal BT8x8 driver by following these instructions:
