Unishilp electronics was founded in 1990 and specialises in the manufacture of auto security systems. The company manufactures a complete range of electronic security products and systems that include cctv monitors, ccd cameras, switchers, matrix, audio/video door phones, remote surveillance systems, access control systems and burglar alarm systems. It also manufactures complete security solutions for cars. The product range includes car alarm system, motorcycle alarm system, parking sensors and power windows roll-up module. The power window roll-up module, according to the company, enhances the safety of the vehicle by automatically rolling up the window glasses one by one. This ensures that the vehicle is safe even if even if the driver or passenger forgot to roll up the window glasses before leaving the vehicle. The alarm system includes a model with code hopping three-channel remote transmitter. Each time the remote transmitter is pressed, it randomly transmits a different code, which prevents disarming the alarm system by copying the code and retransmitting the same.
