The Bosch VJ10E2935 is a single channel video and audio decoder that goes beyond standard decoders with features such as a Compact Flash card slot, wireless card option and built-in motion detection. With up to 2GB of storage capacity, the built-in Compact Flash card slot offers an easy way to retrieve and transfer short term event footage. The Compact Flash card slot will also accept an optional standard 802.11b wireless LAN card, allowing the unit to be installed in areas with no provisions for Ethernet wiring such as inside a camera housing or in a moving vehicle.
