Feel the Power of Modern Security Measures


A license plate recognition system is a mass surveillance technique that uses optical character recognition on images to translate vehicle registration plates. They can use existing closed-circuit television or publically installed enforcement cameras, or purposely designed for the task. They are used by law & enforcement agencies and as a method of toll collection and tagging the movements of traffic or individuals.

LPRS have capacity to store the images captured by the cameras as well as the text/integral figure from the license plate, even have capable enough to stock up snap of the driver. LPRS commonly use infrared technique to allow the camera to take the picture at any time of the day.

LPRS is also known by various other terms:

Ø Automatic license-plate recognition (ALPR)

Ø Automatic vehicle identification (AVI)

Ø Car plate recognition (CPR)

Ø License-plate recognition (LPR)

Technology have played a huge part in this campaign against crime control and in near future we would see the cameras equipped with the License Plate Recognition systems, over the key areas of the country to ensure the security at mass level.
An Internet protocol video camera (IP Video Surveillance), or IP camera, is a category of digital video camera by and large engaged for surveillance, and which unlike analog closed circuit television (CCTV) cameras that can send and receive data via a computer network and through cloud. Although most cameras that do this are webcams, the term "IP" or "net cam" is usually applied only to those used for supervision.
Nowadays security systems make use of CCTV security cameras with Internet protocol technologies. IP CCTV video security systems have better resolution than conventional analog do, more flexible installation, and easier to use features.
Object tracking is the process of tracking a moving object (s) over time using a camera. It has a diversity of uses, some of which are: human-computer interaction, security and surveillance, video communication traffic control, medical imaging. Object tracking system can be a time taking process due to the data size of the video.
Object tracking systems, basically, is taking a video into a digital format (converting analog to digital), and having a computer process the image. This is alike to video motion finding or detection, but more complex. The computer can look at objects, events, colors, light levels, anything in the image that could be called as an "object". Object tracking is the capability of computers to track that object in the video. Suppose a person moving in from of a camera, then walks out of the image to the left. By reading the video, you could understand what happened, but with digital object tracking, a computer tracks the objects and can make certain possibilities without looking at the video. Through object tracking system, we can visualize how tracking system follows a person as they move into a certain area, which activate certain events relaying on the person's movements.
