Offering 360 degree panoramic viewing angle is the one of biggest benefits of panoramic network cameras. The panoramic camera isn’t the new product in video surveillance industry, it has existed for almost a decade, old panoramic security cameras merely can capture 360 degree image, but will loose the detail. After the appearance of dewarping technology (industry experts call it dewarping algorithm), the new panoramic cameras can correct the image distortion to output flat image. Thanks to the fast improvement on image quality and image resolution. In addition to providing the surround view, today’s panoramic security cameras can offer flat image view containing details. So that simply installing a panoramic camera can replace multiple ordinary security cameras to cover the whole area. Consequently, the panoramic network security cameras become popular in recent two years.
To achieve the panoramic view, the security camera may adopt a single Fisheye Lens, or multi-lenses structure design. Using a single Fisheye Lens, the camera can see 360 degree or 180 degree to capture the panoramic image. In order to correct the lens distortion, single lens panoramic security camera will use the dewarping technology to correct the image distortion, and display flat image when users want to check the specific area to know the details. Multi-lens panoramic cameras will have a six or eight lenses to capture the image, then using the image stitching technology to form a panoramic image.
Currently, because multi-lenses panoramic security cameras are too expensive, single-lens panoramic security camera is more popular than multi-lens type. Although both types of camera can provide the similar function. The multi-lenses panoramic cameras can provide better image quality, since the camera has six or eight HD CMOS image sensors to capture the image in every direction simultaneously, while the single-lens panoramic camera has only one lens or image sensor to cover the whole scene.
In the past, the panoramic network cameras are merely deployed in commercial video surveillance fields such as traffic, air port, military, government utilities. The ubiquity of smartphones has helped usher in a new generation of panoramic security cameras targeting to home video surveillance application. These new panoramic security cameras have been designed with smartphones as the center and support watching HD panoramic video. However, many support ePTZ (digital pan/tilt/zoom) function, allowing users to rotate the image to any angle, zoom in to see the details, even offering the VR experience by using the G-sensor.
Resolution is the key factor when you intend to select the panoramic security cameras among different manufacturers/brands. As we mentioned above, the single-lens panoramic cameras rely on a HD CMOS image sensor to capture the panoramic image. Today, you can find these panoramic cameras offer many different image resolution from 1.0-megapixel to 12-megapixel. Making sure to pick up the camera offers higher resolution. Although 1.3 megapixel or 2-megapixel panoramic cameras can provide you crystal clear image when you watch the video on your smartphone. If you watch the video on computers, the image quality will “degrade”, especially after zoom in to magnify the details. A 12-megapixel single-lens camera can ensure the image quality even after zoom in for details.
