Model 4067 is a compact HD digital video recorder (DVR) designed for embedded OEM applications. It captures and records SDI and HD-SDI video and stereo audio to a microSD card. Date and time are maintained by a real-time clock with battery backup. To implement a complete embedded DVR, simply connect power and provide a microSD card.
Simplified block diagram
The board captures video and compresses it to high-profile H.264. Audio from the external microphone or stereo line inputs is digitized and compressed using AAC encoding. The compressed A/V streams are multiplexed and recorded as MP4 or transport stream (.TS) files on a user-supplied microSD card, with file names automatically generated by the real-time clock. Bit rates can be tailored to match application requirements and storage capacity. The 4067 can be set up to start recording automatically after power up.
The DVR has a device USB 2.0 port. When connected to a host computer, the 4067 behaves as a USB storage device, allowing downloading recorded videos without having to remove the microSD card, making configuration changes, and updating the firmware.
