Multiple stream, 1-channel MJPEG/MPEG4 industrial video encoders
- 3 simultaneous video streams for MJPEG and MPEG4
- Video stream up to 30/25 frames/sec at full D1 (NTSC:720 x 480; PAL:720x576) resolution
- Video latency under 200 ms
- 2 Ethernet ports for cascade and Ethernet port redundancy
- Local storage capability with SD card slot
- Industrial design with -40 to 75°C operating temperature
- Free VPort SDK PLUS supported
The VPort 451 is a 1-channel industrial video encoder with MJPEG and MPEG4 video compression that provides up to 3 video streams (2 MPEG4, 1 MJPEG) simultaneously. Video streams can be used for surveillance or recorded for playback analysis. In addition, a video latency under 200 milliseconds makes the VPort 451 the optimal solution for mission-critical video applications demanding real-time video delivery. In addition, the industrial rugged design, which includes a -40 to 75°C operating temperature, built-in fiber Ethernet ports, IP30 protection, and industrial certifications, make the VPort 451 superbly suitable for harsh environments.
