Overview
The VPort 251 is a high performance, 1-channel video encoder in a compact
form factor that is suitable for installation in a variety of locations, including
outdoor camera cabinets. For easier installation, the VPort 251 supports both
panel mounting and DIN-rail mounting (with DK-35A accessory), and includes
a loop-through power output that can be used to power an analog camera.
In addition, the VPort 251 supports full-motion video at D1 resolution (720 ×
