3.1 Product Overview
General
The Siqura® A-80 eight-channel audio and contact closure card offers a compact solution for
multiple audio and contact closure channels over IP. The A-80 can be included in almost any
existing and new CCTV solution to add audio and contact closures to the system.
Models
The A-80 is to be used in MC 11 or similar Siqura power supply cabinets, but it is also available
as a stand-alone module (/SA version). The /SFP version of the A-80 has a pluggable SFP slot for
connections via fiber optic cable. A range of multimode or single-mode XSNet™ SFP devices fit
the empty SFP slot. Front panel LEDs indicate network status, stream status (sync), and DC
power. All models have backup battery power for their clocks.
Audio
The A-80 adds eight separate bidirectional audio channels to the CCTV system. The audio inputs
support either line-level or microphone–level with additional biasing to power electret
microphones. By using RTP/RTCP in combination with network time synchronization (NTP) the
audio streams can be made lip-sync with almost any video stream.
Contact Closures
Eight contact closure inputs can be configured to ‘stream’ contact closure signals to the Siqura
i-NVR, for example, or to activate a signal in the API. In addition, the A-80 offers four contact
closure outputs to connect with third-party PLCs or other telemetry systems. The CC output can
be activated through the API or received CC streams.
Web Interface
Configuration and management are simplified by the access-controlled web interface. Full
in-band control is available through Siqura®’s MX™ Configuration Tool Kit or the HTTP API. The
Siqura A-80 is field-upgradeable.
