Explore: Combining HD Network Cameras with Six Technologies

The combination of high-definition network camera and radio frequency technology At present, radio frequency technology has appeared in combination with high-definition video for practical applications. Because the network camera has a communication (COM) interface, the network camera has control data capture and conversion capabilities. Therefore, it can be connected to an external decoder through the COM interface. Use the COM port to receive data transmitted from the RF, so that the combination of image and radio frequency. At present, such equipment has been applied in some factories and office buildings. For example, this technology can replace fixed punching and illegal person identification (for example, it can give legitimate people wearing only the marked RFID card), and the combination of these two items can help improve many of the more tedious tasks in practice. In order to better reflect the corporate image, it also reflects the value of high intelligence and high technology.

Linkage between high-definition network cameras and various alarm devices The traditional network cameras have an alarm (ALARMI/O) interface. This alarm signal connection can handle the switching level. Therefore, the terminal of the device can also be connected to provide Switch level alarm sensors of various types. After the network camera receives this data, it can encode and process it, and then send it to the TCP/IP network. Through the application software, various alarm response signals can be set in response, such as sound, light alarm and alarm recording.

The linkage network cameras of high-definition network cameras and mobile devices mostly have the capture function, and each network camera has its own independent IP address, and can directly connect with PCs, remote management platforms, and other network connections. We can configure the built-in email client in the network camera. When it is able to access the Internet, the network camera device can also send the captured picture when the alarm is triggered to the specified mailbox via Email. It can also be connected via a COM port to a device that can connect to a SIM card, and can be sent to a designated mobile phone terminal using a short message or a multimedia message. In this way, real-time and intelligent monitoring can be achieved while using only a small amount of bandwidth and cost.

The combination of high-definition network cameras and detection devices is used in the construction of the safe city. In places where dangers are difficult and staffing is difficult, feedback can be provided using the intelligent system attached to the remote monitoring. Such as urban fire prone areas, flood level, dangerous buildings, brittle fractures, dangerous road sections, railways and highways that are prone to landslides, avalanche sections, seismological stations detecting earthquakes, etc., can be set up for detection, identification, and preemption. Intelligent alarm function. In general, devices with temperature detection can detect local temperature changes and trigger alarms; a camera with a cross scale can be installed to detect when the water level is moved to a warning scale on the cross scale and automatically start video display and pre/alarm. So that on-duty personnel can be viewed and processed according to sound and light alarms for the first time to prevent hazards caused by various disasters. Applications such as these greatly reduce the risk and uncertainty of human operations and provide a way to provide stable and reliable data.

The application of motion detection in high-definition network cameras in smart security monitoring systems must have at least video motion detection pre/alarm functions, especially in banks, jewelry stores, shops, warehouses, accounting rooms, armory rooms, secret rooms, Museums, oil depots, and all important monitoring sites need to be set up where safety requirements are high. Of course, this function must be able to eliminate some of the objective interference, especially in the complex weather conditions such as rain, snow, fog, windy, etc., to accurately detect and identify the movement of a single object or multiple objects. Including its direction of movement, movement characteristics. In addition, the detection area of ​​video movement can also be turned on or off individually, which is convenient for adapting to the requirements of entrances, exits, parking lots, and the like in special time periods. When detecting and recognizing the intrusion of a moving human body that is not recognized, the video display and pre/alarm are automatically started, so that the on-duty personnel can perform the viewing and processing according to the sound and light alarm at the first time. In addition, PTZ control commands can be automatically sent according to their movements so that cameras with pan/tilt heads can automatically track objects. If the human body exceeds the surveillance range of the camera, it can also automatically notify other cameras in the area where the human body is located to continue tracking until the criminals are caught.

The intelligent aspect cuts into the high-definition network camera because the front end of the network camera has an operating system, and all the front-end cameras can be equipped with many intelligent algorithms. The intelligent algorithm can directly process the original image information output from the chip, and based on the original image, do some appropriate applications suitable for the feature occasion. For example, you can embed the entrance and exit statistics function. This function can automatically analyze and count the number of people or objects passing through important entrances or designated areas by analyzing the images monitored by the camera. The application of this intelligent function can also be widely applied in service, retail and other industries to help managers analyze business conditions or improve service quality. For example, for the owner to count the number of patrons who visit his shop on a particular day.

The combination of intelligent algorithms and energy saving and environmental protection ideas has opened up another huge market. In party and government agencies, schools, enterprises, and large home environments, intelligent video analysis technology can also be used to eliminate huge energy waste and safety hazards, such as automatically turning off unnecessary lights or turning on lights for people working or adjusting the intensity of lights as needed. Wait. Because the intelligent security video surveillance system can calculate at any time in a certain environment where people walk or work, automatically turn on or enhance the light of the corresponding location, automatically turn off or weaken the light in other locations. In addition, the intelligent algorithm can also automatically analyze whether the person in the actual environment is consistent with the existing in the office or home database to analyze and determine whether there is intrusion by outsiders, and if so, it can be timely pre-alarmed.
