Comparison of Surveillance Cameras for Your IP Camera Systems
To determine the best surveillance camera, you must first understand your objectives. The purposes of your surveillance system include increased safety, reduced theft, improved productivity, or reducing liability. It also includes how quickly you need to be notified of an alarm condition.
Do you want to know when a person steals the laptop from the desk or leaves an unattended package, or do you need to record what happens in the parking lot?
This comparison of IP cameras focuses on the cameras. The camera is only one part of the IP camera system. The complete surveillance system includes a video recording and management system, network switches, and video storage system.
Evolutionfrom Closed Circuit TV to Ubiquitous IP Camera Surveillance
By Bob Mesnik
From the early beginnings of Closed Circuit Television (CCTV), it was somewhat controversial. It was designed to increase our security and safety, but does it threaten our privacy? How has video surveillance changed over the years? This article reviews the history of surveillance and how it has evolved into a technology that has become part of our lives.
Video surveillance is not new; it has been around for quite a while. One of the first recorded application for closed circuit television system (CCTV) was back in 1942. It was used to view the launch of V2 rockets in Germany.
In the US, commercial surveillance applications began around 1947. In 1957 a number of companies such as General Precision Labs (GPL division), provided CCTV camera systems for education, medical and industrial applications.
