The windows of a vehicle are an important asset that protects the driver and passengers. However, when the driver / passengers need to communicate with someone on the outside, that same window becomes an unwanted barrier.
The CNSH model was specifically designed for use in armored cars and law enforcement vehicles in their daily missions. By using an advanced voice sensor, Intervox systems enable high quality communication with the exterior of the vehicle without compromising driver safety and security.
All features (intercom, siren, P.A) are operated from our special hand held microphone to ensure comfortable interface for the driver. To ensure installation simplicity all the components are plug & play and can be quickly installed in any convenient position on the vehicle.
Adding versatility to efficiency, the systems can be costume tailored to meet specific needs and are available in 12, 24 and 42 V.D.C.
