Description

Play video 4011_introductionWatch the video

Model 4013 is a compact digital video recorder (DVR) that is optimized for embedding in OEM systems. It records audio and video (A/V) to USB storage media and can capture JPEG images on-the-fly without interrupting recording.

Two incremental encoder interfaces allow position information to be overlaid directly onto the video. The A/V outputs allow live video, recorded A/V or JPEG snapshots to be displayed on an external monitor. Date and time are maintained by a real-time clock with battery backup. To implement a complete embedded DVR simply connect power, your own custom keypad and a USB storage device. If incremental encoders are not required, see Model 4011.

Wi-Fi

To create a wireless DVR, simply plug a USB WiFi adapter into one of the board's USB ports. Sensoray offers approved WiFi adapters for this purpose (see Accessories tab for details). This allows phones, tablets and laptops to view video and control recording and playback, and also enables the DVR to be operated without a monitor or keypad, which saves space and reduces cost.

Stream formats

The board encodes standard NTSC/PAL composite video using efficient H.264 compression. Stereo line-level inputs are digitized and compressed using AAC encoding. The compressed A/V streams are multiplexed and recorded as MP4 files on a user-supplied USB storage device, with file names automatically generated by the real-time clock. Bit rates can be tailored to match application requirements and storage capacity.

Incremental encoders

Encoder counts are reliably tracked by the incremental encoder interfaces, and automatically scaled to user-configurable displacement units such as meters or feet.

Video overlay

The text overlay generator can locate the current date, time and incremental encoder positions anywhere in the video frame. The date, time and encoder position text is automatically updated every video frame.

USB storage

An external USB storage device is required for DVR operation. If desired, a second USB storage device may also be connected and the 4013 will simultaneously record to both devices. A common application for this is recording to a removable device while creating an archival copy on a non-removable device. USB connectors are located on both sides of the board to facilitate connection to both removable and embedded storage devices.

User interface

The DVR's user interface consists of a user-supplied keypad working in conjunction with the board's on-screen menus. Each keypad connector pin can be routed to any keypad switch and configured to match the control scheme of your custom keypad. If preferred, a standard keyboard can be plugged into any USB port and used to control the DVR.
