Abstract

The utility model belongs to the video monitoring field and particularly discloses an IP camera, which comprises a lens, an image acquisition sensor, an image processing circuit, a network interface, a memory and an alarm module. The memory and the alarm module are connected with the image processing circuit. An external sensor acquires field data and produces a trigger signal to trigger the alarm module. The IP camera records data information in the memory. The field data are monitored by the alarm module of the IP camera. If the field data triggers the alarm module, image data obtained by the image processing circuit are recorded and stored by the IP camera. Therefore, the backup of key data generated during the abnormal condition can be carried out in time. In this way, the loss of the key data due to the damage of a transmission line can be prevented.

Description

A kind of web camera

Technical field

The utility model belongs to field of video monitoring, is specifically related to a kind of web camera.

Background technology

Traditional analog video camera is installed in the following position that these need to be monitored usually, such as places such as residential quarter, road traffic, schools, can long-rangely view the scene information of these monitoring positions by analog video camera.

Because the restriction of technical merit development, present analog video camera, normally directly picture signal is connected monitoring place that is sent to far-end by cable, by monitoring place to its storage of recording a video, such analog video camera can be finished the monitoring to the far-end scene preferably, but owing to be subject to the restriction of cabling requirement, if circuit is damaged, then can't normally collect field data, often for some important burst field accidents, can not the saving scene data, analog video camera is played well adopt the card effect.

Summary of the invention

The deficiency that the utility model exists in order to overcome prior art, provide a kind of can be to the on-the-spot in time web camera of recording image data that happens suddenly.

The utility model can be achieved by taking following technical scheme:

A kind of web camera, comprise camera lens, IMAQ transducer, image processing circuit, network interface, the IMAQ transducer receives the light signal that is gathered by camera lens, through being undertaken to be sent by wired network interface or wireless network transmitter module after image is processed by image processing circuit after the opto-electronic conversion, described video camera also comprises memory and alarm module, memory links to each other with image processing circuit, and alarm module monitoring field data produce triggering signal trigger network camera record image information to memory.

Preferably, described wireless transmitter module is the WIFI module.

Preferably, described memory is the SD card.

Preferably, described alarm module sends alarm signal after receiving the outer sensor triggering signal, and described outer sensor comprises Smoke Sensor and/or humidity sensor and/or temperature sensor and/or infrared sensor.

Compared with prior art, the beneficial effects of the utility model are: except the existing analog video camera of picture can be by the cable network transmit image data, can also be by the alarm module monitoring field data that arrange at web camera, if field data trigger alarm module, by the web camera recording image information to memory, significant data in the time of can occurring for abnormal conditions in time backs up, and prevents that transmission line is impaired and the situation of losing significant data occurs.

Description of drawings

Fig. 1 is web camera module connection structure figure described in the utility model;

Fig. 2 is the module connection structure schematic diagram of network shooting video camera preferred embodiments described in the utility model.

Embodiment

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail.

As shown in Figure 1, web camera described in the utility model, comprise camera lens 1, IMAQ transducer 2, image processing circuit 3, network interface, IMAQ transducer 2 receives the light signal that is gathered by camera lens 1, through being undertaken to be sent by wired network interface after image is processed by image processing circuit 3 after the opto-electronic conversion, described video camera also comprises memory 5 and alarm module 6, memory 5 links to each other with image processing circuit 3, and alarm module 6 monitoring field environmental datas produce triggering signal flip-flop storage 5 recording image informations.

Above-mentioned camera lens 1, IMAQ transducer 2, image processing circuit 3, network interface are the common configuration of general web camera, the utility model is on the basis of existing video camera, be provided with in addition alarm module 6 and memory 5, alarm module 6 can in time be made effective judgement to the abnormality at scene, after the triggering signal that receives alarm module 6 generations, can be the picture signal record that gathers to memory 5, because this picture signal is not subjected to the impact of transmission line, for the data of the record of event under the emergency case, its effect particular importance that seems.Above-mentioned alarm module 6 can external Smoke Sensor, in humidity sensor, temperature sensor or the infrared sensor one or more, Smoke Sensor can monitoring field the smog abnormal conditions, infrared sensor can in time be discovered has the people through out-of-date record, and temperature and humidity can be monitored the site environment sudden change.

Above-mentioned memory 5 can be the SD card, and its mounting means is more convenient.

As shown in Figure 2, for further improving the utility model, web camera described in the utility model also comprises the wireless network transmitter module, and this wireless transmitter module is the WIFI module.By the wireless network transmitter module, make the data of video camera need not be confined to the connected mode of netting twine, make the transmission of view data more flexible, and for the fail safe of view data further raising is arranged.

In addition, for making corresponding prompting for the environment at scene, on-the-spot staff can in time be discovered unusually, send alarm signal after the alarm module 6 receiving sensor triggering signals of web camera described in the utility model.The alarm signal of its reception is not limited to sensor signal, also can by the control signal of far-end transmission, in time point out the staff to take counter-measure.This alarm signal can the light signal flicker, voice signal etc.

In addition, for web camera described in the utility model, in order to obtain clearly image, except the processing to light of front end camera lens, Sensor section, the image processing part also is a ring very important in the mega pixel web camera.Generally, Sensor section is provided with embedded picture processing chip and processes some better simply functions, the functions such as automatic exposure, Automatic white balance check and correction and automation focusing then must be by rear end ISP (Image Signal Processing: image signal processing chip be processed), to obtain good image effect.

In addition, at encoding context, view data has been adopted H.264 coding processing, compared with traditional Mpeg4 video compression format, H.264 saved 50% code check, and Internet Transmission is had better support function.H.264 introduced towards the encoding mechanism of IP bag, be conducive to the transmitted in packets in the network, the streaming media of video in the network enabled.H.264 coding method has stronger anti-bit error performance, can adapt to the transmission of video in the wireless channel of packet loss height, serious interference.H.264 coded data is supported the hierarchical coding transmission under the heterogeneous networks resource, thereby obtains stably picture quality.H.264 coded data can be adapted to the transmission of video in the heterogeneous networks, and the network compatibility is good.

Above said content, it only is the preferred embodiment of the utility model, when the scope that can not limit with this utility model enforcement, the content of namely generally putting down in writing according to the utility model claim and utility model specification is made simple equivalence and is changed and modification, all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the utility model.
