Security

Every S1800e series device comes with a unique SSL (Secure Sockets Layer)

certificate for securing its IP link. SSL is a commonly used protocol for

managing the security of IP message transmission. With the SSL protocol, the

following data: Web Control Data, and VSIP communication are secured. For

more information on activating the SSL security, refer to the SConfigurator

User Guide, Web Interface User Guide or your Nextiva Administration Guide.

Frame Rate and Performance for the

Single- and Dual-Port Devices

The S1801e and S1802e encoders support H.264 and MJPEG video up to

D1/30fps on all streams simultaneously for up to 10Mbps.

The available video frame rates (frames per second) of each encoder are:

NTSC-1, 2, 3, 3.75, 5, 6, 7.5, 10, 15, or 30 fps

PAL-1, 2.5, 5, 6.75, 8.33, 12.5, or 25 fps

Encoders 1, 2 and 3 are H.264 and Encoder 4 is MJPEG.

A typical scenario would be using encoder 1 as the recorder, since it is the

primary H.264 encoder. Encoder 3 or 4 can be used for viewing or recording,

depending if you want to view live video in H.264 or MJPEG.
