Provide monitoring or emergency evacuation. In detail, when the external cable 26 is normally supplied with power, the controller 24 turns off the light-emitting element 18 and activates the video module 12 to perform the monitoring function. When it is detected that the external cable 26 loses power, that is, a fire occurs to destroy the power system of the building in which the warning device 10 is installed, the controller 24 can use the backup power source 22 to drive the light-emitting element 18 to output illumination light to provide escape. Stable and sufficient emergency light source.

In addition, when the external cable 26 is powered normally, the controller 24 activates the video module 12 to capture the image of the monitoring space through the night vision assisting unit 121, and temporarily stores the image to the memory module 14. The night vision auxiliary unit 121 can be an infrared trigger unit. The infrared trigger unit can perform image capturing in an environment without a background light source, and can selectively trigger the shooting of the video module 12 when a person in the monitoring space passes to detect the energy saving.

After the video module 12 is triggered and the image of the person passing through the monitoring space is captured, the captured image is temporarily stored in the memory module 14, and then the controller 24 starts to compare the image and the built-in data of the memory module 14. The preset image of the library 241 determines whether the person is a person authorized to pass or a suspicious person without authorization according to the comparison result to decide whether to start storing the recorded image for reference.

Further, when the image and the preset image match, the controller 24 deletes the temporary image from the memory module 14 and does not continuously store the recorded image of the video module 12. When the two do not match, the controller 24 stores the recorded image of the video module 12 in the memory module 14 to become a movie, and completely records the behavior of the person who enters the monitoring space without permission. The warning device 10 can reduce unnecessary recording time to save the capacity of the memory module 14.

In summary, the present invention has an infrared anti-theft video module 12, a memory module 14 encapsulated inside the fire and moisture proof protection member 16, a power failure detection module 20 for detecting the function of the external power system, and a connection to the illumination. The backup power source 22 of the component 18 is integrated to form a warning device 10 that also functions as a home security monitoring and emergency response. The warning device 10 of the present invention must use the power-off detection module 20 to detect the power supply state of the external cable 26 at any time to determine the actuation of the light-emitting component 18 and the video module 12.

The light-emitting element 18 provides emergency illumination when the external cable 26 is abnormal, and does not turn when the external cable 26 is normal to save power of the backup power supply 22. The video module 12 performs image capturing through the trigger of the night vision assisting unit 121, so that the home environment monitoring can be achieved without sufficient ambient light. The video module 12 of the present invention further has an image recognition function, which can determine whether to store the recorded video by comparing the preset image of the built-in database 241 with the image captured by the video module 12, thereby saving the memory mode. At the same time, the capacity of the group 14 can immediately record the suspicious persons in the monitoring space to facilitate criminal reconnaissance.

It is worth mentioning that after the memory module 14 is packaged inside the protection component 16, it cannot be freely replaced, and only one transmission connector, such as a universal serial bus (USB), can be reserved for external data transmission. path of. The transmission connector can only use the wired transmission method to output the data of the memory module 14, thereby preventing the data from being deleted or modified by the remote person by remote control.
