A new community with a capacity of 50 houses built in the suburbs of Hsinchu, Taiwan, recently deployed a smart flood prevention system using remote surveillance and flood detectors. Cogi Digital Surveillance installed the system consisting of an Avtech HD network camera and I/O controller.
The housing standard in the community is three-floors high with an independent garage in the basement. However, a few months ago the community, which includes neighbouring stores and households, experienced a serious flood that caused serious damages. Therefore, they were eager to seek a solution for water level monitoring and remote surveillance.
The HD network camera provides an instant notification service on mobile devices when the water level sensors are triggered, while the controller offers four inputs for N.O/ N.C and four outputs for relay electronic devices. The user placed the water level sensor in the ditch near the garage exit as the input and connected it to broadcast system in the community for output. In addition, the switch of the rolling shutter is set as the other ouput. On the condition that the water level reaches the upper limit, the rolling shutter will be shut down automatically and triggers the broadcast system. The broadcast system then makes an announcement to remind the guard to close the water gate.
The users configured the camera to send a video clip via mobile devices whenever the water level reaches the upper limit. It helps the community guards to monitor the water level remotely during heavy rains. For example the guard closed the water gate immediately during a typhoon that struck the island in February when the alarm was triggered and successfully avoided the flood. “It really saves my time without checking the garage front door frequently when heavy rain happens,” said one of the security guards in the community surnamed Wang.
