VideoCrunch® Unit

AVT’s VideoCrunch® Unit, or VCU, is a real-time wireless video surveillance unit with the ability to both record and transmit video. Its wireless capability means that the VCU can be installed in a remote location where wireline access is not available, or in a vehicle. The user can dial in to the VCU using a Windows application program on a PC or laptop computer. When triggered during an emergency situation, the VCU relays a video stream to the home base computer, notifying security personnel of the problem and allowing for a quicker response.

VCU 3000
Wireless Narrowband Mobile MPEG-4 Encoder/Decoder Transceiver


Moving or remote vehicles and assets are kept in constant contact with the resources needed in critical life-saving situations. Excellent quality live video [k1] is transmitted from anywhere in the world to select monitoring stations by connecting over low-cost narrowband cellular, satellite phone, FM and other wireless networks.

Continual digital recording with event-triggered transmission allows instantaneous 24-hour wireless video and audio monitoring of expensive assets, wherever they are in the world.

Applications Meeting the Rugged Requirements of:

  • Airline Security (Transmit live video from airplanes direct to the ground)
  • Emergency (EMS, police, hazardous materials, fire, 911, search and rescue)
  • Shipping (trucking, rail, marine, aircraft, armored vehicles)
  • Transportation, (taxi, bus, train,)
  • Remote Assets (film industry, news, military, municipalities, public water supplies, government, embassies, offshore, international, mining, forestry, oil and gas, pipelines)
  • Security (perimeter, remote areas, solar powered remote units, security companies)
