A: "DigitalTimeCodeEmbedded" time information of the video function is to be embedded in the MPEG data stream , instead of the data stream is divided into two and then do compare , so the actual time of each picture will be stored . When the user wants to find a video record or a specific period of time , which is quite handy . If the network cameradoes not support this feature , users must search the entire video stream , which will take considerable time . Some cameras have the function to simulate the application , but it is not precise enough in terms of time recorded, a video stream with the "DigitalTimeCodeEmbedded" , is also called "SmartVideo", and can be done by some other client software more applications. Other advantages include providing DigitalTimeCodeEmbedded watermark in the video stream . Due to the time information is embedded in the video stream , so once the video has been tampered with , the time information will disappear from the video data , and can not be recovered, so the time information can be used as a watermark to prevent the video is fake , so that users can easily identify video authenticity.
Q: Are there IP Camera offer motion detection function ?
A: Yes . Network camera have built-in motion detection provides functionality rather than through software to do . In general, if implemented in software motion detection , response this time from the incident to the camera will have a larger time difference , in terms of professional monitoring is therefore quite unsafe.
Q: scope of application of network camera are there?
A: mainly used in professional security systems, remote monitoring from the scene of the real-time images over the network. Network cameras can easily be integrated into large, complex systems, but at the same time can be used as a stand-alone system to be used in a more simple monitoring environment. The product can be used to monitor some of the more sensitive and requires a high degree of vigilance in the area , such as buildings, banks and shops , these sites can be in the vicinity of the central control room to monitor, remote locations or by different security center to monitor .
IP Camera can also be used in some replace analog cameras , especially in law enforcement installation locations such as tunnels, intersections and so on. Network cameras can also be used to manage access control security , whether human or vehicle can be recorded topography and time passes , so very easy retrospective search. The video data can be stored by the network on a remote server , without worrying about data theft issues. Network camera is very easy to connect to the existing IP network , and can provide the country with high-quality video in real time over the network . For some sensitive areas , such as computer rooms , bank counters or other remote locations , available through a local area network or the Internet , using the most economical and simplest way to watch closely . IP Camera can not only strengthen the chain store monitoring to ensure that all was well , and also provide a high degree of protection office security , such as reception , meeting rooms , etc., when an accident occurs , you can search for what people have to enter the computer room to do the appropriate treatment . network camera for manufacturing firms is also a very useful tool , supervisor in the office or at home , you can monitor the plant's automated production equipment, other machinery and production lines , and so on . In addition, if with PTZ (Pan / Tilt / Zoom) enabled network dome camera , you can also do more complex monitoring, like being at the scene.
