Axdvr 2000
Digital Video Recorder Board
We implemented all necessary functions for DVR from moving image shooting to compression, storage and transmission on the FPGA. This realizes the low cost, compact and long-term embedded needs.
- NTSC input 4ch
- NTSC monitor output 1ch
- JPEG compression function
- Compressed image recording to HDD connected to SATA connector
- 4ch simultaneous simultaneous storage at 120fps
- Real time image streaming with Gb Ethernet
- This board Control
- Operation switch, display LED
Application
- Surveillance for devices handling money or cash cards such as ticket vending machines, ATMs, POS cash registers, unattended parking lots
- Records for investigating causes of problems such as factory production and manufacturing equipment
- Records such as railroads, buses, taxis, elevators Recording evidence image
- Remote operation and recording of places where human intervention is difficult such as ocean and post-site
- Monitor stocks, restaurants / buffets and other stocks, customer flow etc.
- Office, hospital, educational facilities, apartments, etc. Monitoring suspicious individuals
- Sample Software for PC
- Time designation display of saved images, real-time image display, multi-image display
- Save to Motion-JPEG (.avi) on PC HDD
- Microsoft Visual C ++ sample source code
