GSM alarm systems with 3G, DVR, video surveillance rising

Makers are also boosting system reliability with dual GSM and PTN coverage.



  • Shift to 3G: Makers are moving toward 3G, in particular W-CDMA for its greater bandwidth. The technology switch enables real-time video streaming and higher image resolution. CDMA2000 models will be launched in the next six to 12 months.
  • Video surveillance, DVR rising: Most of the latest releases have a built-in 300,000-pixel CMOS camera that delivers QCIF to VGA clips or up to XGA still images. Some makers are adopting 2MP CMOS sensors and 720p resolution. Units with DVR are shifting to MPEG-4 recording from M-JPEG. PTZ control and external camera modules are future add-ons.
  • Dual-network operation: An increasing number of products support GSM and PSTN for better reliability. These can auto-switch between networks, ensuring uninterrupted operation.
  • Enhanced cosmetic design, user interface: Compact and all-in-one systems with large color LCDs, touch controls, an OSD menu and voice prompt are emerging. These have flat front panels with a mirror finish covering the screen and keypad to blend with interiors.
