Carry out voice prompt alarm；Vibrations alarm can be the sense of touch alarm that can produce vibrations, believe when receiving controlling alarm
Number when, alarm signal can be sent by producing vibrations；Visual alarm could be arranged to LED, when receiving controlling alarm
During signal, light warning signal is gone out by the lasting flicker or long brighten the hair of LED., can when being alarmed in specific implementation
To be alarmed using one or more in above-mentioned alarm, the invention is not limited in this regard.Such as, it is possible to use only Buzzing type
Alarm carries out Buzzing type alarm, or can also be reported simultaneously using Buzzing type alarm and vibrations alarm simultaneously
It is alert, to strengthen warning level, allow users to pay attention to and receive the alarm signal that alarm is sent in time.
Alternatively, in order to effectively obtain the relevant information during theft, the burglar alarm dress in the utility model
Putting also includes：At least one camera 240 being electrical connected with central control module 220.Specifically, central control module 220
It is connected with above-mentioned at least one camera 240, when central control module 220 receives the electric signal of the output of pressure sensor 210
When, trigger at least one camera 240 and open image pickup mode, and the image in target area, i.e. case are absorbed by the camera
Live view is sent out, in order to preferably grasp thief's information and its larceny information.Wherein, above-mentioned triggering mode can be by
Those skilled in the art are configured according to actual conditions, and the utility model is not restricted to this.Camera absorbs the side of image
Position can be adjusted by user according to the needs of oneself, and the utility model is not construed as limiting to this.
Further optionally, in order to ensureing the supply of electric energy in burglar alarm, burglar alarm of the present utility model
Power module can also be further set in device, for providing electric energy.Wherein, power module can be with central control module electricity
Property is connected.In specific implementation, power module can be connected by wired modes such as wires with central control module, or can also
It is integrated on central control module.Herein, the set-up mode of power module can be by those skilled in the art according to actual feelings
Condition is configured, and the utility model is not restricted to this.
In summary, the burglar alarm provided by the utility model based on pressure sensor is simple in construction, cost is low
It is honest and clean and easy to use, it can solve the problem that the burglar alarm for moving in room applied to user in the transient places such as hotel, hotel at present
The problems such as apparatus structure is complicated, and production cost is higher and inconvenient for use, can accurately sense larceny that may be present simultaneously
Alarm signal is issued the user with, the occurrence of consumer articles are stolen is effectively prevent, protects user benefit.In addition, this reality
Spot picture can also be enrolled by default camera by applying the anti-theft device in example, be user tracking and grasped robber
Larceny surreptitiously both provides great convenience, user benefit has been obtained further guarantee.
The various modules that are previously mentioned in the utility model, circuit are by hard-wired circuit, although some of which mould
Block, circuit are integrated with software, but the utility model it is claimed be function corresponding to integrated software hardware circuit, and not only
Only be software in itself.
It should be appreciated by those skilled in the art that the apparatus structure shown in accompanying drawing or embodiment is only schematical, table
Show logical construction.Wherein it is probably as the module that separating component is shown or may not be physically separate, as module
The part of display is probably or may not be physical module.
Finally it should be noted that be：Listed above is only specific embodiment of the utility model, certain this area
The utility model can be modified by technical staff and modification, if these modifications and variations belong to the utility model right and wanted
Ask and its equivalent technologies within the scope of, be considered as the scope of protection of the utility model.
