Welcome to Security Camera Integration Wiki


Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them. This can include observation from a distance by means of electronic equipment (such as CCTV cameras).
Surveillance cameras are video cameras used for the purpose of observing an area. They are often connected to a recording device or IP network, and may be watched by a security guard or law enforcement officer. Cameras and recording equipment used to be relatively expensive and required human personnel to monitor camera footage, but analysis of footage has been made easier by automated software that organizes digital video footage into a searchable database, and by video analysis software (such as VIRAT and HumanID). The amount of footage is also drastically reduced by motion sensors which only record when motion is detected. With cheaper production techniques, Surveillance cameras are simple and inexpensive enough to be used in home security systems, and for everyday Surveillance.

What is Video Standard?

Different areas of the world use different video standards. North America uses NTSC, Europe uses PAL and SECAM, South America uses PAL-M, PAL-N, PAL and NTSC. Almost every area of the world has a mixture of video standards. If your CCTV/recorder/camcorder support multi-systems, you can use either PAL or NTSC camera. With a multi-system video recording format, you expect an PAL tape to be reproduced as a standard digital PAL signal, and the same machine if fed with a NTSC tape will reproduce it as a standard digital NTSC signal. A multi-system interface recorder can also be expected to make a perfectly normal PAL recording of an PAL input signal, and a perfectly normal NTSC recording of a NTSC input signal. A NRSEC representative can provide professional advice in selecting the correct Surveillance security camera.
