The CWT-400 SIP to ONVIF Bridge
Aside from protocol constraints, users wishing to connect a SIP-enabled audio source to an ONVIF-compliant VMS are confronted by the fact that most VMS equipment assumes the audio equipment to be ‘always on’. This can be a problem because configuration of such equipment on a VMS often involves a discovery process in which the VMS looks for a streaming source, registers it and then assumes it to be permanently available. Furthermore, most examples of VMS equipment have no ability to initiate streaming from front-end devices which may be required to be switched off, for example to save power.
The CWT-400 solves these problems and allows front-end SIP-enabled devices to work with ONVIF-compliant video management systems.
The CWT-400 gets your audio through!
A Unique Solution!
- The CWT-400 acts as a bridge between SIP-enabled audio devices and ONVIF-compliant video management systems. Audio sources see the CWT-400 as a SIP client and can call it to start an audio stream, treating the CWT-400 as a codec. At the same time, the video management system will see the CWT-400 as an ONVIF-compliant video camera. The CWT-400 sends a plain video image to maintain the connection and at the same time sends the audio stream which is received by the VMS just as if the sound was coming from a video camera.
- In the design of the CWT-400 emphasis has been placed on exceptional audio fidelity. It accepts Opus-encoded audio and converts this to AAC. These are two of the highest quality compression standards in the broadcast and security industries. The conversion between the two is direct - there is no intermediate transcoding.
- The CWT-400 can be supplied in:
- 2U rack-mountable frames of up to 10 devices
- In sets of 10 in a mobile, carry-on flightcase (special order)
