4W AES256 82Mbps 350MHz-4GHz Customizable IP66 Manpack IP MESH Video Transmitter
I. Product Introduction
The ZKManet-2251UM is a rugged IP66 bodypack metro transceiver with a rugged design. With 4 watts of output power and a twist-lock battery for easy replacement, it is ideal for a variety of mesh deployments such as public safety, armed police, fire control, and robotics. Its multi-hop capability dramatically increases transmission distance, covering 1-2 kilometres of non-line-of-sight (NLOS) per hop. Data rates of up to 82Mbps make it easy to transmit video, data and audio simultaneously, and AES256 encryption technology ensures secure data transmission.
