Please note, this card does not include our surveillance software. It is intended for software development using our (free) Video4Linux2 driver.
- Hardware compression MPEG-4 capture card
- 4 port video inputs, 1 port video output
- 4 port audio inputs, 1 port audio output
- 120FPS recording @ 352×240, 120FPS @ 704×480The Bluecherry BC-04120A is true hardware compression card supported by our Video4Linux(2) driver. Recently tests with this driver has shown siginificant CPU / memory saving over standard software compression cards. For example, 56 cameras encoding @ 704×480 with video and audio uses approximately 5% CPU (On a dual core 2.4ghz) and approximately 450Mb of memory.
This card has several features not commonly found on traditional Linux supported MPEG-4 encoders, including:
- Each port has a MJPEG and MPEG-4 encoder, each can be opened separately.
- Each device shows up as a Video4Linux(2) device and you have access to each encoder using standard Video4Linux APIs.
- Each port is loaded up as an ALSA sound device, allowing for encoding G.723 audio from each audio input.
- The driver exposes the video output as a ‘display’ device, allowing you to control the video output (specify which inputs are displayed on the composite output)
- Our driver is available in the latest kernel releases, in the ‘staging’ directory. Note: The device has the following features, which are currently not supported in the driver: Hardware (on-card) motion detection. Hardware motion detection is currently only supported in our software.
