Wireless Transceiver

Securitex Industrial Wireless Audio and Video transceiver

Securitex Wireless video transceiver Ver.2.1 has been specially redesigned and tested for use in almost all industrial environment where laying of cables for surveillance and security application is virtually impossible. The transmitter and receiver module are setup and house in an IP 65 industrial grade enclosure manufacture by “Marlanvil” Italy. The cable inlet and outlet are install with very high quality bullet cable gland that is waterproof to prevent water and dust from entering the housing. In very corrosive environment this system is also very suitable as the enclosure prevent corrosive chemical vapor from entering the enclosure and damage the delicate electronic component. The Dipole whip not-removable omni directional antennas that protrude from the enclosure are also secure by a watertight bullet cable gland. To ensure that stable voltage are input into the transceiver system we have provided in the enclosure a industrial grade (Mean well S-35-12) 35W 12VDC Single Output Switch-mode Power Supply c/w voltage stabilizer.

In explosion proof environment usage Nitrogen gas can be used to pressurize the enclosure such that hydrocarbon or inflammable gases cannot enter the housing and cause explosion (Please consult the plant engineer for used in ex-proof location).   

System Application.

The systems are specially designed for used in Oil, Gas and Petrochemical complexes. This system can also be use in military camp, warehouses, schools, campus, semiconductor, electronic plants and area where cable laying is not practical etc.
