Abstract

The invention provides a digital camera giving alarm and preventing theft in real time. The digital camera comprises a camera body and is characterized in that the camera body is provided with a theft-protective alarming device. The alarming device comprises a locking notch arranged on the camera body, as well as a locking head and a key; the locking head is internally provided with an alarm. On appearance, the alarm is small and hidden and does not affect the portability of the digital camera when in use; an infrared remote controller is used for controlling the switching of the alarming lock, therefore the remote control function works stably and is not interfered; a sensor is used for controlling alarm, the real-time performance is high, the whole cost is low and the digital camera is beneficial to mass production.

Description

technical field [0001] The invention relates to a camera, more specifically, to a real-time alarm and anti-theft digital camera. Background technique [0002] With the popularization of consumer-grade 3C products, almost every household now has a camera, but the size of the camera is generally small. Even a professional camera is larger than an ordinary card machine, but it can be easily taken away. , so digital cameras have also become valuables that are easily stolen. Chinese Invention Patent Application No. 200510023435.9 discloses a method for realizing digital camera anti-theft with bluetooth technology. At the digital camera end, if the user chooses to start the alarm function, then open its watchdog timer interruption and bluetooth reception interruption, and report to the remote control Send a command word to open the alarm, and start timing by the watchdog timer, once it overflows, it will report to the police, if the digital camera receives a call signal from the ...
