Interfaces

6.3. SNMP

The Simple Network Management Protocol (SNMP), part of the internet protocol suite, can be
used to monitor network devices such as the C-54 E for conditions or events that require
administrative attention. For more details, refer to appropriate literature on SNMP.
The C-54 E supports in-band SNMP. Via SNMP several status variables can be read and traps
can be generated on events. C-54 E SNMP settings can be configured through the Device
Management web page (see section 7.10.2).
The SNMP Agent is MIB-2 compliant and supports versions 1 and 2c of the SNMP protocol.
SNMP Agent settings can be edited through group 11 of the service MIB which holds all
SNMP-related settings (e.g. trap destinations). The MIB database can be downloaded from
the Optelecom-NKF website.

6.4. HTTP and RTSP

The Siqura Protocol for Video Codecs & IP PTZ Dome Cameras is an HTTP-based protocol
enabling easy integration of the C-54 E with third-party products. The protocol consists
mainly of different CGI (Common Gateway Interface) programs called for listing and
configuring parameters.
RTSP (Real-Time Streaming Protocol) is used to negotiate media streaming in RTP (Real-
Time Transport Protocol). The purpose of RTSP is to establish and control one or more
time-synchronized streams of continuous media, such as video. It does not typically deliver
the continuous streams itself. RTSP acts as a network "remote control" for the C-54 E. The
C-54 E maintains a session labelled by an identifier. RTSP controls a stream which may be
sent via a separate protocol, independent of the control channel. For example, RTSP control
may occur on a TCP connection while the data flows via UDP.
For more details on controlling C-54 E media streams through HTTP and RTSP, and a
specification of the Siqura protocol and its parameters, refer to Optelecom-NKF's
Codec/Camera Programming Interface specification. You can download this document from
the Optelecom-NKF website.
Example
Use the following URL format to get a stream into, for example, VLC or QuickTime.
where:
<x> is the video input number (Use 1 ... 4 for the C-54 E).
<y> is the media type of the required encoder (either mpeg2, mpeg4, or mjpeg),
<z> is the logical encoder number (1 or 2)
rtsp:// <ip-address of encoder>/VideoInput/<x>/<y>/<z>
