3.3 Overview of functions

Thermal IP camera

The thermal IP camera VOT-320 is a complete network video surveillance system inside a weather-proof housing. It provides high sensitivity, uncooled long wave thermal images. Six choices of lenses are available (both narrow and wide field of view) and frame rates of 8.33 or 30 Hz.

VOT-320 is designed to combine the benefits of thermal imaging with the well-proven Bosch IVA features. Thus a unique product was created that offers early detection and display of irregularities over large areas even with poor visibility or absolute darkness. Neither dense smoke nor bad weather conditions as heavy fog or snow affect visibility. With a VOT-320 there is no need for natural or artificial lighting of the area of interest.

The camera incorporates a network video server. Its primary function is to encode video and control data for transmission over an IP network. With its H.264 encoding, it is ideally suited for IP communication and for remote access to digital video recorder and IP systems. The use of existing networks means that integration with CCTV systems or local networks can be achieved quickly and easily. Video images from a single camera can be simultaneously received on several receivers.

Outstanding image quality

The camera uses a Vanadium Oxide (VOx) focal plane array with an image resolution of

320 × 240 pixels that delivers outstanding image quality and sensitivity. The Bosch designed digital video processing system optimally handles the thermal image format without compromise. Temperature differences of 50 mK or less are made visible. Video processing features include multiple automatic, dynamic image optimization algorithms, as well as polarity control (white hot/black hot). Automatic flat-field correction (FFC) grants proper calibration of the detector throughout the operation.

Receiver

Compatible H.264 enabled hardware decoders (for example the VIP XD) can be used as receivers. Computers with decoding software such as Bosch Video Client or computers with the Microsoft Internet Explorer Web browser can also be used as receivers.

Video encoding

The VOT-320 uses the H.264 compression standards. Thanks to efficient encoding, the data rate remains low even with high image quality and can also be adapted to local conditions within wide limits.

Tri-streaming

Tri-streaming allows the data stream to be encoded simultaneously according to three different, individually customized profiles. This creates two full H.264 streams that can serve different purposes and an additional M-JPEG stream.

Multicast

In suitably configured networks, the multicast function enables simultaneous real-time video transmission to multiple receivers. The UDP and IGMP V2 protocols must be implemented on the network for this function.

Encryption

The VOT-320 offers a variety of options for protection against unauthorized reading. Web browser connections can be protected using HTTPS. You can protect the control channels via the SSL encryption protocol. With an additional license, the user data itself can be encrypted.
