Enhanced models carry GSM/GPRS functions

摘要

GSM/GPRS models offer cheaper, innovative solutions to GPS as latest offerings sport added functions, smarter looks, wider range. Mainland China and Hong Kong SAR makers are focusing on functionality and cosmetics to produce new designs for car alarm and electronic security systems. Hong Kong makers have introduced voice-activated function, code-learning capability, shock and current sensor functions, remote ignition and air-conditioning control, and longer remote-control ranges. Mainland China makers forecast the trend will be for long-range, two-way FM/FSK systems although the standard one-way model with LED screen remains the mainstream. Technology for GPS-based systems is acknowledged to still be in its infancy, but the popularity of GSM networks in mainland China has made it possible for a handful of makers to come out with GSM-based car security systems.
