In the future, network monitoring will show two trends. First, centralized monitoring is an alternative to traditional decentralized and isolated monitoring. The network is the bridge to achieve this transformation. The second is the intelligent background application. In the past, a large amount of video data could not be fully and timely utilized, and many useful information was difficult or impossible to extract and save. Compared with analogue monitoring, what is the difference between the two advantages?
The benefits of digitization and networking are: With the development of video analytics technologies, multimedia databases, and artificial intelligence technologies, we can gradually and automatically extract a large amount of information from video streams that can be transmitted, saved, and retrieved. Drive other data and easily accomplish tasks that are difficult for humans to accomplish.
IP network monitoring has unparalleled advantages over traditional monitoring: Any networked place can build a network monitoring system. Because the traditional wiring and line maintenance costs are eliminated, the installation cost of the network monitoring system is greatly reduced. For the user, IP network monitoring is not limited by time and place. In the case of authorization, it can be monitored on demand at any time, and plug-and-play can be implemented. The use mode is very convenient. As a result, IP network monitoring was consistently considered by the industry to be the main trend of future video network monitoring.
With the gradual development of video surveillance, IP network monitoring is no longer confined to the application of enterprise-level industry customers. IP network monitoring applications will gradually develop toward civilians, and use video surveillance data for public services, such as home security, child care, Check the application of chain management and other aspects.
One of the advantages of the webcam is that it enables video surveillance to exceed the resolution and frame rate limitations of conventional PAL/NTSC systems, resulting in high-definition video with extremely high image detail. Even a 1 million-pixel network camera provides nearly 3 times the resolution of analog CCTV cameras. High-end network cameras can provide up to 5 million pixels or even more resolution.
However, high resolution is not the only progress of network cameras in the field of clear images. The introduction of HDTV into the field of video surveillance has really promoted the application of HD in the field of video surveillance. With megapixel resolution, HDTV means high-definition image detail. In addition, an HDTV HD network camera that truly complies with industry standards ensures excellent color reproduction - full frame rate and 16:9 aspect ratio format.
The introduction of the MPEG-1 compression standard laid the foundation for digital television and promoted the development of modern television standards throughout the world. Motion Picture and Television Engineers - The SMPTE is the HDTV standards development organization. As the authoritative global film, television, video and multimedia standard setter, the organization has identified the two most important standards: SMPTE296M and SMPTE274M. SMPTE296M defines a progressive scan using a resolution of 1280×720 pixels, and SMPTE274M defines a resolution of 1920×1080 pixels for interlaced or progressive scan.
The HDTV application webcam means that the image makes people's eye observation more comfortable, with full video rate of 25/30 frames and excellent color returning to the clinic. The wide-screen 16x9 image provided by HDTV is the ultimate choice after years of research. It contains more effective video information. In fact, HDTV standards that are truly fully compliant with the HDTV standard provide a higher level of picture quality than ordinary megapixel or HD cameras, providing better full-frame-rate video.
In the fields of airports, railways, casinos, city surveillance, passport control, and factory production control, HDTV HD network video can provide more perfect solutions.
Megapixel and HDTV webcams have many advantages. There are still many applications, standard resolution network cameras can provide the best solution. Standard resolution usually means D1 (720 × 576 pixels) resolution, SVGA (800 × 600 pixels) resolution. In complex light scenes, standard resolution cameras can be used to the maximum advantage when extreme sensitivity and wide dynamic range are required. Some standard definition cameras offer a higher frame rate than the traditional 25/30 frames per second and are suitable for capturing fast-moving objects.
The key is what you need to see? Of course, the demand for video surveillance changes tremendously. The most fundamental problem is usually two different preferences:
Panorama overview: In this case, the goal is to get a panoramic overview of the scene. For example, in a shopping mall, the main purpose of installing a camera may be to monitor and view its actions in the flow of people rather than personal identification. Or check whether the parking lot is full or free, instead of identifying or reading license plates for individual vehicles. For the above applications, enough resolution is required to cover the scene.
High detail: If you need to be able to identify people or objects in the scene. This may be a point-based monitoring, to clearly see the customer purchase of each item, or in some cases, the need to be able to identify the face. High-detailed images can be monitored more closely with web cameras equipped with zoom capabilities. HDTV network cameras will provide more detailed, clear details and higher resolution images than standard definition network cameras.
Seriously analyze your video surveillance needs. In general, the answer lies in the combination of SD network cameras, HDTV network cameras and megapixel network cameras. By balancing requirements, an IP monitoring solution can have the best cost-effectiveness and meet the required image availability.
