The difference between HD and megapixel surveillance camera resolution
With the popularity of IP video systems in the video surveillance industry, acquiring high resolution images through megapixel video has become an indispensable setting. In addition, the use of HDTV standards is also extremely common in the video consumer market. The images acquired by the new generation of cameras are basically HD or megapixel. Because "HD" and "megapixel" both point to a better level than traditional images, they often show the same side. But in fact, they are very different.
In fact, high-definition broadcast television (or consumer market) resolution should not be seen as the ultimate goal of video surveillance. Megapixel cameras already offer higher resolution than broadcast TV, so a clear and clear explanation is obviously necessary.
Megapixels and HD have an understanding that HD is a part of megapixels. HD is defined based on its unique resolution, frame rate, and aspect ratio. Any camera, when its number of pixels reaches 1 million, can be called a megapixel camera. In the current security market, the lowest number of pixels in the megapixel field is 1.3 million pixels, and the entire span ranges from 1280x1024 resolution (1.3 million pixels) to 3648x2752 resolution (10 million pixels). The field of megapixel cameras will continue to expand and have been adapted to a variety of application needs. For example, ArecontVision has been expanding its own megapixel specification, including the existing 130, 1080p, 200, 300, 500, and 10 million pixels, and the upcoming 20 million pixel solution.
Cameras defined in HD have a resolution of 720p or 1080p. The two numbers 720 and 1080 represent their vertical resolution. Therefore, the resolution provided by the 720p HD camcorder is 1280x720 (921600 pixels, not megapixels), and the resolution provided by the 1080p HD camcorder is 1920x1080. The HD video format also uses a 16:9 aspect ratio (relatively, 5:4 and 4:3), and its video frame rate is also standard at 60fps, 50fps, 30fps, or 25fps (taken from the TV standard) .
Strong IP Video System Power According to TechNavioInsights, IP surveillance has seen rapid growth in end users and large organizations. The advantages of software for driving and control, video scalability and wide availability are often marked as important elements of growth. In any case, among the many features of IP surveillance, providing a wide range of video resolutions is the most prominent one. Together with H. With 264 compression and programmable control resolution and bitstreams, the new video resolution standard is more simply defined, sometimes completely based on demand. With IP megapixel video, cameras assigned to monitor critical areas can get images of any resolution, even up to 10 million pixels (3648x2752 - almost 5x 1080p camera resolution).
Based on the capabilities of today's megapixel cameras, surveillance at specific locations can be improved at different resolutions, and cameras of different resolutions can access the same network. As a result, when critical areas are monitored with low resolution and slow frame rates, key areas can still be monitored and recorded with high resolution quality. Video analytics can also be used to launch megapixel video streams and only activate automatically. This method optimizes existing network transmission capabilities and video storage space, ensuring the value of bandwidth.
Megapixel cameras can provide higher resolution, which allows system designers to use smaller cameras to cover larger areas without losing detail information, thereby reducing investment in supporting facilities and installation costs. It also reduces the initial installation costs of the system. These benefits translate directly into lower total procurement costs and higher return on investment.
Resolution diversity is just one of the advantages of IP megapixel video. Another important element is the ease of access to the network system, which has led to the rapid development of IP megapixel images. In the past, each camera had to occupy a separate coaxial cable loop to connect to the VCR. As a result, the cost of wiring increased exponentially. However, the network infrastructure makes it possible to connect several cameras with fewer lines. Power over Ethernet (PoE) allows the camera to supply a single CAT-5 network cable with video and control signals (no need for local or distributed power supply). This is a very efficient and simple installation solution.
In addition, the megapixel camera offers excellent resolution, making it possible to have clear and accurate live and video digital pan/tilts. As a result, megapixel cameras virtually eliminate the need for mechanical pan-tilt cameras. In fact, mechanical components are both prone to failure and very expensive.
Many integrators (and end-users) have made the mistake of thinking that IP megapixel systems are complex and difficult to use. It is true that these systems cannot be installed and used in the traditional sense. This is true, but the partnership between camera suppliers (such as ArecontVision) and a large number of DVR and VMS suppliers has paved the way for simple integration of the system. It also regulates ready-to-use IP networks. The creation of industry standards (such as PSIA and ONVIF) is making the software required for out-of-the-box use less or less. In addition, today's rich megapixel camera can adjust its resolution and frame rate, which is also a concept of today's monitoring applications. These alternative projects give designers greater flexibility and confidence in their design.
Jump into megapixels around H. 264 Advances in Video Compression The demand for bandwidth and storage based on IP-based megapixel image systems has dropped to the same level as standard definition image systems. The price of a megapixel camera is also comparable to a standard definition camera. When you consider the ability to have fewer megapixel cameras than analog cameras can cover a larger area, it is believed that the result will be savings in construction and labor costs. This is why IMS Research predicts that the installed capacity of network video surveillance systems will inevitably grow significantly, and that more than half of the factory network cameras by 2014 will be HD or megapixel resolution.
Whether you prefer a megapixel camera to your actual needs or a branch HD camera, today's rich, high-resolution cameras provide powerful imaging tools for in-line experts. It is self-evident that the so-called better systems are all excellent images based on high-resolution camera technology.
