Wireless CCTV technologies take video security on the move
Wireless technologies are widely applied in data transmission, and video surveillance is already taking great benefit of various wireless applications. The simplest solution is to equip a camera with a built-in wireless transmitter to carry recorded content over the air to a receiver. However, what sounds straightforward enough turns out to be highly complicated when large video surveillance systems are at stake.
A major challenge for such a system is how to ensure that the level of wireless connectivity meets the capacity demands for transferring the vast amount of data produced by hundreds, even thousands, of recording cameras.
The challenge is even greater in public transportation systems where vehicles, and hence on-board video recorders, are constantly on the move. The wireless network needs to provide enough capacity and connectivity to access on-board data as well as to allow the data to be automatically transferred from moving vehicles to a central system for analysis and storage.
For many public transportation operators, failures in wireless data transfer mean that they are not able to fully benefit from their security systems, and manual work is needed to overcome shortages within automatic operations.
Teleste’s innovative solutions address the challenge of high-capacity wireless transfer
Utilizing frequencies not commonly used by Wi-Fi and other data transmission technologies, Teleste’s new multi-gigabit wireless full-duplex data transfer technology offers the public transportation industry extremely reliable, high-capacity wireless connectivity. The technology reaches over 4 gigabit vehicle-to-ground and inter-carriage transmission speeds with minimal interference in transmission.
Higher transmission speeds make it possible for the operators to easily manage a large amount of on-board video and data, e.g., by accessing the recordings through a wireless connection and offloading them to central storage automatically during a short stop at a station. By ensuring that on-board video recordings can be managed from the operation center, the technology brings operators significant benefits in terms of improved operational efficiency, reliability and situational awareness.
Thanks to the multi-gigabit transmission speed, the wireless network infrastructure can be built with fewer devices and hence to total system cost for the operator is lower.
In addition, Teleste’s new, innovative concept called ‘Wireless offline offload’ aims at solving constraints caused by lacks and shortcomings in the wireless infrastructure itself. The patent-pending concept will open up additional possibilities in designing extended network transmissions that are less affected by insufficient wireless infrastructure outside vehicles. Reducing the level of investments needed, the concept improves transmission availability throughout the public transportation ecosystem.
