WT-V400A is specifically designed for international customers and partners who are facing market competition for high quality and cost competitive products, quick delivery and prompt service.

Video, audio and data transmission interfaces are implemented with small daughter boards which can be mounted onto the mother boards according to customer requirement, the configuration can be done outside the factory, so that it can be serviced base on functional part, this will give great advantage to oversea customers on time and cost for product maintenance.

WT-V400Aˇs structure is carefully designed to achieve both flexible configure and robust quality.

Standard modular design also improves product quality and delivery time for some none-frequently used configurations.

WT-V400Aˇs mother board is suitable for both 4U 19〔 chassis and stand alone case, this gives great advantage for installation.

WT-V400A uses industry-proved circuits to achieve high video quality to meet the high video quality requirement of high end video surveillance system.

Transmission capacity:

Video: 1~8 channels (base structure)

Audio: 1~8 channels

RS485/RS232/Switch: 1~8 channels

Ethernet: 1 channel

With CWDM technique, maximum number of video channels of 64 can be achieved

Customized interfaces might be made with fewer effort based on the modularized structure
