The era of analog security camera systems has essentially come to an end, owing to the many shortcomings and performance issues that the systems have failed to address over the years. Analog cameras can only provide protection for the immediate area. When users try to expand the field of view beyond the immediate proximity, the images become blurred. Professional grade IP Megapixel cameras are designed to address this anomaly.
Difference Between Analog and IP Security Cameras
The distinction between analog and IP security cameras lies in the quality of video. From an amateur's perspective, analog cameras offer TV picture quality, whereas IP Cameras offer HD resolution. Technically, this analysis is true since IP based cameras offer megapixel resolution, with the quality ranging from 1 megapixel and going as high as 10 megapixels.
Common Applications of Megapixel Resolution IP Cameras
1. License plate recognition
Megapixel resolution enables IP security cameras to capture great detail. This powerful capability comes in handy for business security applications such as LPR, whereby organizations may wish to capture and store the details of all vehicles coming in and going out of their premises. The LPR cameras are fitted with powerful lenses, as well as image processing software to enable them to operate in all types of conditions. LPR cameras capture surveillance video like any other IP security camera. However, the powerful software is able to lift vehicle license plates from the video and send the details to a database for storage.
2. Facial Recognition
Organizations that have to deal with heavy human traffic within their premises face various security challenges. The same can be said of law enforcement agencies, which are charged with the responsibility of securing sensitive installations such as airports and other public areas. Megapixel resolution offers a solution in the form of facial recognition. Similar to license plate recognition, IP security cameras with powerful lenses and image processing software can be deployed to man public installations, with the aim of enhancing security. The powerful software is able to capture and match facial patterns and other identifying features, and stores this information in a database for future reference.
