優化安全傳感器電池壽命

　　安全傳感器經常受到電池壽命短的困擾。通過結合低功耗無線協議和低功耗處理器，這不一定是個問題。

　　寬帶服務提供商（BSP），如有線電視和電信公司，正準備推出住宅安全服務-基于ZigBee的無線規范來增加他們目前的語音、視頻和數據服務。ZigBee使BSP提供一系列的附加服務，如安全、能源管理、照明控制、保健應用，這統稱為安全、監控和自動化（SMA）服務。

　　安全傳感器的電池壽命是一個關鍵的考慮實用性，成本效益，和市場的SMA方案驗收，一系列因素，包括無線通信范圍、互操作性、認證、生態排名很高，在現場可升級性。Ember公司開發和控制的SMA的解決方案，公司專門針對接觸傳感器的電池壽命延長。本文討論了這一工程伙伴關系的結果。

　　Ember Corporation is a leader in low-power， wireless networking solutions based on the ZigBee protocol; it has developed industry leading solutions for a variety of low-power ZigBee devices in addition to security sensors， including gas meters， door locks， and battery-powered thermostats. iControl is the leading provider of SMA solutions that enable BSPs to roll out next-generation services to their customers. In addition to contact sensors， iControl’s SMA Platform integrates a wide variety of ZigBee sensors， including motion sensors， smoke alarms， glass break detectors， CO detectors， key fobs， wireless keypads， garage door openers， and more.

　　Based on the fact that the average residential security system is used for seven years， BSPs typically require that contact sensors have a minimum of three years of battery life for an initial product offering， and a roadmap leading to battery life spans of seven to ten years.
