Remote Video and Audio Transmission system

The FastTX remote video transmission product is the benchmark for live transmission of outstanding quality video and audio. Developed to satisfy the most stringent requirements, FastTX encompasses years of technological leadership of the video transmission market for security and surveillance applications.

FastTX utilises LAN/WAN network systems or data links to protect and monitor your sites, 24 hours a day, anywhere in the world.

Remote, multi-site management

Centralised management to improve efficiency and reduce personnel costs. Live video, two-way audio, remote camera control and flexible integration capabilities provide full remote site surveillance and control eliminating the need for on-site security staff. Efficient and fast transmission technology, even over slow data links, provides complete surveillance capabilities. Multiple users can view live activity without comprising site security.

No Alarms Missed

Automatic transmission and storage of high quality snapshot image sequences from six concurrent alarm events eliminates the threat of decoy alarms.

Rapid and accurate assessment of site activity is provided by the display of high quality stored alarm images in a split screen format.

Outstanding Picture Quality

Using state of the art digital video compression techniques, FastTX provides rapid initial image transmission and the fastest updates of all activity. Outstanding picture quality is maintained regardless of the link speed.

Comprehensive Remote Control

Industry standard serial interfaces allow easy integration with a wide variety of telemetry, matrix switcher, access control and image storage systems.

High Quality Audio

Integrated listening ability assists in the alarm verification process, while transmission of the operator's voice to the site provides instant intruder control. FastTX uses sophisticated audio compression techniques to ensure that high quality; bi-directional audio uses the minimum possible bandwidth of the communications channel.

Standards-compliant performance

FastTX can be installed to be fully compliant with British Standard, BS8418. This standard specifies superior quality equipment, best practice installation and monitoring requirements that will ensure long term, high performance operation for the end user.
