HD IP Camera is coming

HD IP Camera is coming
One of the advantages of the network camera video surveillance is to be able to go beyond the traditional PAL / NTSC standard for resolution and frame rate limit, bring extremely high image detail of high-definition video. Even 100 megapixel Network Camera provide close to three times the resolution of analog CCTV cameras, high-end network camera can provide up to 500 million pixels, or greater resolution.
However, the only progress in the field of clear images of high resolution is not a network camera, HDTV introduce the field of video surveillance, real push HD in the field of video surveillance. With megapixels of resolution, HDTV means high-definition image detail. In addition, a truly industry-standard HD IP Camera, to ensure excellent color also attending - full frame rate and a 16:9 image aspect ratio format.
MPEG-1 compression standard has laid the basis of the digital TV, to promote the development of modern TV standards around the world. Of Motion Picture and Television Engineers congregation - SMPTE HDTV standards-setting organization, the organization as the authoritative global film, television, video and multimedia standards makers to determine the two most important criteria: SMPTE 296M and SMPTE 274M. SMPTE 296M defines a 1280 × 720 pixel resolution progressive scan, SMPTE 274M defines a resolution of 1920 × 1080 pixels interlaced or progressive scan.
HDTV the application IP Camera means images people's eyes observe more comfortable, also attending - 25/30 full frame rate video and excellent color. HDTV wide screen 16 × 9 image, the final choice totally cut - after many years of research, it contains more effective video information. In fact, truly in full compliance with the HDTV standard definition Network Camera than ordinary megapixels or HD IP Cameraprovide a higher level of image quality, and provide a better full frame rate video.
In airports, railways, casinos, city surveillance, passport control, factory production control in areas such as HDTV HD network video can provide the perfect solution.
Current HDTV has three display resolution format: 720p (1280 × 720, progressive), 1080i (1920 x 1080 interlaced), and 1080p (1920 × 1080, progressive), where p stands for the English word progressive (gradually line), and i mean interlaced (interlaced).
Compared to HDTV, general megapixels network camera does not observe Ge - any video standard is more similar to the number of pixels of the image sensor with a digital camera. For example, the number of megapixels Network Camera usually provide limited frame rate. Megapixels network camera also has many good applications, such as in the application of extreme need details of the video image, for example, the bank monitoring, transportation hubs and other places.
In addition, more than 3 million high-pixel HD IP Camera supports "multi-sight" technology, in a surveillance scene divided into multiple sub-scenes, each sub-scene video stream independent output. This is not only true alternative multiple ordinary clear camera with a high pixel camera, but also the global horizon and sub-sight contact. Support digital PTZ (pan / tilt / zoom) is also megapixels camera provides another advantage.
Megapixels and HDTV HD IP Camera have many advantages. There are still many applications, the standard resolution Network Camera can provide the best solution. Standard resolution usually means that D1 (720 x 576 pixels) resolution, SVGA (800 × 600 pixels) resolution. In complex lighting scenes, the need for extreme sensitivity and wide dynamic range, the standard resolution cameras to maximize advantage. Some standard-definition cameras provide higher frame rate than the traditional 25/30 frames per second for capturing fast-moving objects.
The key is what you need to see it? Of course, change is a huge demand for video surveillance. The most fundamental problem is usually the preferred choice of two different:
The panoramic Overview: In this case, the aim is to get a scene panoramic overview. For example, installed in shopping malls, the main purpose of the camera may be in the crowd monitoring and view their actions, instead of personal identification. Or see if the parking lot is full or empty space, rather than the identification of individual vehicles or read the license plate. For these applications, the need to have sufficient resolution to cover the scene.
High detail: If you need to be able to identify people or objects in the scene. This monitoring is based on the point, to clearly see each customer purchase, or in some cases, you need to be able to recognize human faces. High detail images can be through the installation of Network Camera with zoom capability, and closer monitoring. HDTV IP Camera will provide more detail than standard definition Network Camera, crisp details and higher resolution images.
A careful analysis of the video surveillance needs. Normally, the answer lies in a combination of standard definition Network Camera, HDTV megapixels IP Camera. By balancing the needs of an IP surveillance solution, you can have the best cost-effective and meet the availability of the desired image.
The company has produced a H.264 compression format HD IP Camera, model IP-EU812. Product evaluation presented later, thank you for attention
