We offer a range of audio products that are typically used to complement CCTV-systems and enable two-way-audio. We offer speakers and microphones for communication with sites under surveillance, e.g. to deter intruders, open gates or play back audio messages in case of certain alarms such as guidance to exits. We also offer equipment for audio recording, for instance in case of a robbery in a bank. These possibilities are naturally supported in our Detec Next VMS and by a number of our NVRs and cameras.
