Description
Technical field
This utility model relates to technical field of video monitoring, particularly relates to a kind of video monitoring apparatus and system.
Background technology
Existing video monitoring apparatus many employings the following two kinds mode: one be coaxial video line and twisted-pair feeder with
Time use, be kept completely separate by Double-strand transmission control command, i.e. control line and video line.Wiring cost is high,
When connecting up the most at a distance, the necessary overstriking of line, and also wiring distance is restricted.Another kind is to pass through
Video line superposing control line transmits together, and control command is added in video field blanking and passes through by back-end controller
Video line transmits.For HD video, the high-speed decoding chip that needs are specified, and the mode of control command
Various, decoding command format is limited, causes cost to be substantially increased.To sum up, two ways all exist cost high,
The defect of poor universality.
Utility model content
This utility model embodiment technical problem to be solved is, it is provided that a kind of with low cost, versatility
Strong video monitoring apparatus and system.
In order to solve above-mentioned technical problem, this utility model embodiment proposes a kind of video monitoring apparatus, bag
Include:
Controlled video camera；And
It is electrically connected to described controlled video camera, for video signal and control are referred to by coaxial video cable
Order carries out the processor of dissection process, wherein, is integrated with field blanking identification circuit, and electrical connection in processor
In described field blanking circuit, for eliminating the delay circuit of redundant data.
Further, the main body of described delay circuit is voltage comparator.
Further, described video monitoring apparatus also includes being electrically connected to processor, is used for gathering client's body
Part card information and/or the identification module of finger print information.
Further, described processor is integrated on circuit board.
Correspondingly, this utility model embodiment additionally provides a kind of video monitoring system, including as above
Video monitoring apparatus, also includes being connected to described processor by network, can carry out described controlled video camera
The server remotely controlled.
This utility model embodiment is by proposing a kind of video monitoring apparatus and system, described video monitoring apparatus
Including controlled video camera；And it is electrically connected to described controlled video camera by coaxial video cable, for regarding
Frequently signal and control instruction carry out the processor of dissection process, wherein, are integrated with field blanking identification in processor
Circuit, and be electrically connected to described field blanking circuit, for eliminating the delay circuit of redundant data, Jin Erda
This cheap, highly versatile and the technique effect of dependable performance are arrived.

Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment
Can be combined with each other, with specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Refer to Fig. 1, this utility model embodiment provides a kind of video monitoring apparatus 1, described video monitoring
Device 1 includes controlled video camera 10 and processor 20.
Controlled video camera 10 be can carry out focusing according to control instruction, the video camera of acquisition parameters adjustment etc..
Please with reference to Fig. 2 and Fig. 3, described processor 20 is integrated on circuit board, and described processor 20 leads to
Cross coaxial video cable and be electrically connected to described controlled video camera 10, for video signal and control instruction are carried out
Dissection process.Wherein, processor 20 is integrated with field blanking identification circuit 21, and is electrically connected to described field
Blanking circuit, for eliminating the delay circuit 22 of redundant data.Preferably, the master of described delay circuit 22
Body is voltage comparator.Specifically, in control instruction, short high level lasting time is short, and redundancy is many,
Inconvenient analytical data frame head, uses field blanking identification, the mode of time delay to get rid of lasting useless signal,
The high level becoming long facilitates the analysis of data frame head.
As a kind of embodiment, described video monitoring apparatus 1 also includes being electrically connected to processor 20, uses
In gathering customer's identity card information and/or the identification module (not shown) of finger print information.And then, described
Video monitoring apparatus 1 can not only carry out the routine works such as Car license recognition management, additionally it is possible to related personnel's
Identity card and/or finger print information are identified record, and relevant personnel are also carried out while normal work registration
Management.
This utility model embodiment additionally provides a kind of video monitoring system, including video monitoring as above
Device 1, also includes being connected to described processor 20 by network (can be cable network or wireless network),
The server 2 that described controlled video camera 10 remotely can be controlled.
To sum up, the video monitoring apparatus 1 of this utility model embodiment and system, except bringing wiring side
Just, save outside the beneficial effects such as Construction Cost, also make system can use the general monolithic of low speed of low cost
Machine reduces design difficulty, and the complexity of circuit board also decreases, it is not required that use for HD video
The special chip solution specified, reduces totle drilling cost, and can carry out large-scale use at general field.
Embodiment the most of the present utility model, for those of ordinary skill in the art
For, it is possible to understand that can be to these embodiments in the case of without departing from principle of the present utility model and spirit
Carry out multiple change, revise, replace and modification, scope of the present utility model by claims and etc.
Co-extensive limits.
