COVERT A/V SURVEILLANCE  Wireless Recording In most cover operations, Wireless Surveillance is the utmost importance because A/V signals can be transmitted to covert team member to monitor the situation. Wireless surveillance can also be risky because transmitting signals can be detected by RF Detectors.

COVERT A/V SURVEILLANCE  Line Recording No wireless A/V signals are transmitted in Line Surveillance operations. it therefore poses no danger. Smaller size or miniature A/V recorders are highly recommended so that it can be body worn Line surveillance has its disadvantages because covert teamn members cannot receive A/V signals in life threatenning and hostile operations.

AUDIO JAMMER   Distorts any Discreet voice recordings (Analog or Digital) Personal protection of conversations from the non-authorized recording Distance of supression: for digital recording :0.5m to 2m for cassette recorder : 0.5 to 2m

GSM Video Surveillance System GSM Video Surveillance System (VSS) is designed to help to monitor and detect such incident of truck hijacking, theft of goods being transported and staff collusion The data signals provide actual visual images as opposed to the existing GPS System that provided only geographical location. The actual images viewed via central monitoring provides crucial information and evidence when crime occurs.  How System works Embedded Mobile Unit (EMU) is deployed to site and transmits video data via EDGE network Data is transmitted to VSS control center which acts as the server Client’s provided password can monitor respective EMU via internet on PDA, Laptop or Desktop at any location using VSS client  Advantages Long Distance and large area surveillance  Embedded mobile units can be dispatched without any wiring limit Adjustable image size and quality  Peak transmission rate of up to 153.5kbp Various recording modes at control centre Easy expansion  Unique encryption (data safety)  Why its different from others The ONLY mobile data transmission system that can be used wherever EDGE network is available Easy Installation and configuration Wireless Real time monitoring from any location Easy recording Support replay, pause, variable speed function Allows multiple client monitoring Recording remotely done away from site under surveillance GSM Video Surveillance System - E-Brochure   BONE CONDUCTION What is the bone-conduction? Sound reception: The means to transmit the sound wave from the outer ear and eardrum to the inner ear via air vibration in eardrum (i.e. The sound wave is transmitted from the outer ear path and the tympanum filled with the air to the inner ear) is the “Air-conduction”, and this sort transmission uses air as its’ medium. The transmission of the sound wave also has another approach, which is to directly transmit the sound wave into the inner ear by the skull vibration and does not need the participation of the outer ear and eardrum. This means of transmission through the solid bone in the skull is known as the “Bone-conduction”. Sound transmission: When people vocalise; besides transmitting the air vibration wave through the mouth, the throat tone can also transfer the vibration wave to the skull. By collecting the signal of the skull vibration, it can achieve the voice transmission through the bone-conduction.
