Security & Home Automation

摘要

WHEN it comes to security and home automation, you want the fundamentals to be solid. Any system must have battery backup and it should meet the Australian Standard and offer more than one reporting path. That could be dual-SIM or SIM and blue cable. When it comes to sensors, including cameras, you want good sensor designs and reasonable quality. In the case of PIRs, a dual pyroelectric sensor with a welldesigned lens is to be preferred. Quality mirror optics offer better performance and dual technology sensors offer lower false alarm rates in challenging environments, though they are not commonly found in typical security and home automation solutions.
