Further, described delays time to control unit comprises: timer, has a trigger end and output terminal, and described timer trigger end receives described trigger pip, and described timer output end exports described control signal.
Further, described alarm unit comprises: one first resistance, and its one end is coupled to the output terminal of described timer, to receive described control signal; One NPN triode, its base stage is coupled to the other end of described first resistance, grounded emitter; One hummer, its negative pole is coupled to the collector of described NPN triode, and it is just coupling and is being coupled to a VCC voltage.
Further, described start and stop unit comprises a self-supporting switch, and described self-supporting switch connects with the current supply circuit of described timer.
Further, described video camera also comprises standby power supply.
Compared with prior art, the utility model has the advantages that: by above scheme, when video camera is stolen, will certainly be moved, so now displacement detecting unit just can detect this behavior, and exports a trigger pip to delays time to control unit, then delays time to control unit is after certain time delay, export control signal, send alerting signal to control alarm unit, reach the object of reminding Security Personnel.Wherein, delays time to control unit needs the reason exporting control signal after time delay again, be in order to preventive maintenance personnel encounter video camera because of carelessness, cause trigger alarm, simultaneously, by arranging above-mentioned switch, maintenance personal can be started by switch or close warning function, thus maintenance personal is after encountering video camera because of carelessness, close warning function by switch, avoid unnecessary misunderstanding and trouble.

Embodiment
Referring to figs. 1 through Fig. 3, embodiment of the present utility model is described further.
A kind of analog video camera with anti-theft feature, comprise casing 1, camera 2, video processing module, communication module, memory module and power module, also comprise an anti-theft prompt module, anti-theft prompt module comprises: displacement detecting unit 400, whether be moved in order to detect video camera, and export corresponding trigger pip Sp when video camera is moved; Delays time to control unit 500, exports corresponding control signal Sc in response to trigger pip Sp after time delay; Alarm unit 600, sends alerting signal in response to control signal Sc; And start and stop unit 700, have a switch, start and stop unit 700 is for enabling or close anti-theft prompt module, and switch is installed on casing 1.
Below, will be further described for anti-theft prompt module:
With reference to Fig. 2, displacement detecting unit 400 comprises 3-axis acceleration sensor and controller, wherein, 3-axis acceleration sensor is for detecting the displacement of video camera, controller is coupled to 3-axis acceleration sensor, when 3-axis acceleration sensor detects that video camera is moved, controller exports trigger pip Sp(low level).In this embodiment, the model of 3-axis acceleration sensor is MMA845xQ, controller can be single-chip microcomputer, its model is PIC16F1823, because the combination of 3-axis acceleration sensor and single-chip microcomputer carrys out inspected object displacement, for technology well known to those skilled in the art, therefore, the present embodiment repeats no more its concrete principle of work.
In one embodiment, with reference to Fig. 3, delays time to control unit 500 comprises timer, and this timer has a trigger end and output terminal, and wherein, trigger end receives trigger pip Sp, and output terminal exports control signal Sc.As we can see from the figure, this timer is made up of one piece of 555 timing chip, wherein, 1 pin ground connection of 555 timing chips, 2 pin and 6 pin are by a resistance R3 ground connection, and 2 pin and 6 pin are also coupled to described VCC voltage by an electric capacity C2, and 4 pin and 8 pin are coupled to VCC voltage equally, 5 pin are by another electric capacity C3 ground connection, and 3 pin are as the output terminal of timer.Therefore, the principle of work of timer is, after 2 pin of 555 timing chips receive low level trigger pip Sp, through time delay a period of time, exports the control signal Sc of high level from 3 pin.
In one embodiment, with reference to Fig. 3, alarm unit 600 comprises resistance R4, NPN triode Q1 and hummer.Wherein, one end of resistance R4 is coupled to the output terminal of timer, with reception control signal Sc; The base stage of NPN triode Q1 is coupled to the other end of resistance R4, grounded emitter; The negative pole of hummer is coupled to the collector of NPN triode, and just coupling of hummer is coupled to VCC voltage.Therefore, the principle of work of alarm unit 600 is, when resistance R4 receives the control signal Sc of high level, NPN triode Q1 conducting, makes hummer obtain electric, send alerting signal.
Further, with reference to Fig. 3, start and stop unit 700 comprises a self-supporting switch 3, and self-supporting switch 3 connects with the current supply circuit of timer, namely connects with the VCC voltage input circuit of 555 timing chips.Therefore, when self-supporting switch 3 is pressed, 555 timing chips obtain electric, enter duty, and when self-supporting switch 3 resets, 555 timing chip dead electricity, even if receive trigger pip Sp, also can not export control signal Sc.So, maintenance personal just can when encountering video camera because of carelessness, by cancelling warning function by self-supporting switch 3.
Further, video camera also comprises standby power supply (not shown).By arranging this standby power supply, preventing thief from first cutting off the power supply of video camera, after making the dead electricity of video camera, causing anti-theft prompt module not work.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
