No matter what mix of analog or digital surveillance equipment a business has, it is always a good idea to know how they function. The functionality of any CCTV or IP camera video system focuses on two things: image resolution and field of view (how much ground is covered on the screen). The resolution at which a security camera records is helpful in identifying things such as license plates and facial features. The recording resolution must be accessible in real-time and later playback from a DVR recorder. Video Resolutions Currently Available Video resolution categories can be divided up into analog CCTV systems, which are usually low definition, and digital high definition. There are many subdivisions inside these categories according to the number of pixels, screen size, and panorama (field of view). The reason why no chart dealing with video resolution comparisons would be complete without an analog section is that there are still so many low definition analog systems in use. They are often the only choice for a smaller business. Cameras using analog technology are often integrated with digital systems as hybrid surveillance security coverage. Further developments in surveillance technology have brought in panoramic megapixel cameras that can operate at a 180-degree or even 360-degree angle. The video resolution of these applications will be provided in the chart as well. The information on the resolution comparisons was derived from impartial field tests. CCTV Resolution Chart The terminology and numerical parameters listed below describe the image size (resolution is measured in pixels), how it is transmitted, how it looks when displayed on a screen (large or small), and how...

The popularity of CCTV cameras in business and residential premises in New Haven county CT continues to grow, and for one unlucky criminal, his repeated attempts at carjacking were caught in glorious technicolor, for all to see. Even the police seemed shocked at the sheer audacity of the suspect, a man called Juan Laporte who is 32 years of age. The determined man attempted to carjack a number of people at the gas station, even wrestling one poor woman to the ground in a desperate attempt to grab her keys. Not only were the incidents captured on the gas station CCTV system, but so were the heroic actions of a passerby who tried to help the woman by kicking the assailant. The good news is that Laporte was subsequently arrested and subsequently charged by police. Ironically the poor woman of the attempted carjacking was trying to help Laporte after he crashed his car further up the road, according to WWLP. The woman pulled over and offered him a lift to the nearest petrol station so that he could call the police to report the incident. In a shocking turn of events, Laporte then decided to thank the woman by trying to steal her car. Having failed to take her car the determined criminal then chose to jump into another man’s car as he was pumping gas. The determined owner of this vehicle held on valiantly to the car steering wheel, as Laporte attempted to drive away from the gas station. Determined not to steal the car Laporte frantically tried repeatedly to drive it between the road and the garage...

License plate recognition (LPR) is an effective way to screen traffic in parking areas or moving through entry gates. However, proper setup is critical. While license plate recognition might seem like a highly-advanced feature you’d only see in use by law enforcement or in the latest action movies, improvements to both camera image quality and surveillance infrastructure have drastically reduced the cost of this beneficial surveillance tool. If your business uses dedicated parking areas, controls access via an entry gate or checkpoint or simply wants an additional layer of information to help with convictable evidence, LPR will help! LPR Basics Since LPR uses video analytics software to perform most of its functions, most high-definition IP cameras or HD-over-coax systems are ready to use the feature without extensive modification or additions to hardware. Using the video from your cameras, LPR software will scan any footage for license plate numbers and compare it to a database. Upon finding a match, the system will perform tasks you assign depending on your needs. While most think of using LPR to capture criminals, locate stolen vehicles or provide convictable evidence for court proceedings, it has other general uses for businesses as well. When paired with a gate or access system for a parking lot or parking structure, the systems can help to provide access to secured areas without the need for physical interaction—such as a dedicated gatekeeper. When someone arrives at the gate, the system scans their plate and once matched within the database will open the gate. The system might also work for logging access times and maintaining accountability. Considerations when Implementing LPR...
