Hanwha Vision says that its IP Audio system brings a compelling new audio capability to its leading video surveillance offering, adding another layer of security and a further criminal deterrent.
According to the company, the system can be independently operated as a standalone solution or it can be linked to a video surveillance system.
It also supports the Session Initiation Protocol (SIP) which is the Standard for Voice over IP (VoIP) systems.
Up to 256 speakers can be accommodated without an audio server, with any number thereafter up to 512 speakers requiring an audio server.
Pre-recorded or real-time messages
Hanwha Vision says that the IP Audio system can broadcast real-time or pre-recorded messages, including text to speech messages issued by a control centre.
In addition to public address announcements, these can prevent incidents of criminal or antisocial behaviour from happening. Messages can also be broadcast via a microphone.
A range of applications
The IP Audio system can be used to broadcast messages or music in public areas including train stations, retail shops, hospitals, schools and more.
When linked to video surveillance, the IP Audio system can complement perimeter protection with audio warnings if a potential intrusion is detected within a virtual area.
If the system senses human activity in a restricted area that indicates a possible breaching of a fence, an audio message can be relayed asking any intruders to keep away.
Maintaining ambience
The system also includes a background music option, using MP3 or WAV files to help maintain a pleasant atmosphere when announcements are not being made.
Music automatically continues once an announcement has been completed. This can be scheduled days, weeks and years in advance and volume can be adapted to different IP speaker groups.
Flexibility and control
Hanwha Vision says that operators can control when and how messages are broadcast — either pre-recorded in advance or live via a microphone.
When integrated into a video management system (VMS), operators can select the camera they wish to trigger an event within the system.
They can also select which speaker they want audio messages to come from.
