Comparison between Solar-Powered Active Wireless Infrared Detector
and Active Wired Infrared Detector
Solar-Powered Active Wireless Infrared Detector Active Wired Infrared Detector
Dif.1 Ditching and wiring of signal wire or power cord not required during installation Ditching and wiring of signal wire or power cord required during installation
Dif.2 Check-up of signal wire or power cord not required during maintenance Check-up of signal wire or power cord required during maintenance
Dif.3 Easy to install, which is a simple project Not easy to install, requiring long-term construction period, which is a complex project
Dif.4 Automatic shielding of sunlight interference, strong light interference indicator provided on the host, no fault alarm Possible fault alarm when subject to sunlight interference
Dif.5 In case of lightening strike, the wireless system could not be wholly disabled and could be easily recovered, with little loss. In case of lightening strike, the wired system could be wholly disabled and could not be easily recovered, with much loss.
Comparison between Solar-Powered Active Wireless Infrared
Detector & Grating and Metal Anti-theft Window
Solar-Powered Active Infrared Detector & Grating Metal Anti-theft Window
Dif.1 Installed outdoors, and small in size, it does not affect the integrate beauty of house decoration. Installed outdoors, but large in size, it affects the integrate beauty of the house decoration.
Dif.2 Not required to enclose the window, without impeding your view of scenes out of the window. Required to enclose the window, which causes depressive feeling and brings down the quality of living.
Dif.3 The unenclosed window would be an escape exit in case of emergency. The enclosed window would not be an escape exit in case of emergency.
Dif.4 In case of theft, it alarms on the spot, which would scare the thief away immediately. It is able to guard against the theft, but, at the same time, it would become handrails and supports for the thief to climb the wall.
Dif.5 With the active infrared technology, it alarms on the spot whenever the thief destroys or climbs the window. Easy to be jimmied open
Comparison between Solar-Powered Active Wireless Infrared Detector
& Grating and General-Purpose Pyroelectric Burglar Alarm
Solar-Powered Active Wireless Infrared Detector& Grating General-Purpose Pyroelectric Burglar Alarm
Dif.1 Installed outdoors, it alarms immediately once the thief tries to come into the house. Installed indoors, it alarms after the thief comes into the house.
Dif.2 Installed outdoors, without impeding indoor activities. Installed inside the house, the alarm has to be disarmed for indoor activities.
Dif.3 Adoption of solar-powered wireless technology ensures high energy efficiency without any damage to the decoration. The wired alarm would destroy the indoor decoration, while the wireless alarm requires frequent change of batteries.
Dif.4 Round-the-clock protection, without frequent arming and disarming of the system. Frequent arming and disarming of the alarm is needed for the owners to go out and come in.
Dif.5 Application of active infrared detection theories to the design helps to settle the problem of false alarm Application of the Pyroelectric theory results in a high rate of false alarm.
