Business facilities and institutions must monitor their perimeters to ensure safety and proactively prevent trespassing, theft and vandalism. Similarly, large venues need to maintain order and ensure that public safety or information announcements are heard quickly and clearly.

Our horn loudspeakers and amplifier module can be integrated into Video Management Systems (VMS) based on the ONVIF standard and in addition they can be an integral part of SIP based solutions including full support of SIP cloud-based server providers.
