PRODUCT DESCRIPTION
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts).
More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
ip
IP cameras excel in capturing high definition, megapixel images, as technology has improved so have the various IP cameras. The introduction of analytics through IP encoders has now made it possible to not only view a camera's image but also the monitored notification and snapshot of the motion, object tracking, people counting, face detection, and voice filters.
IP solutions provide the end-user with a crystal clear image of the software filter that accompanies these solutions have helped in security as well as production processes.
ANALOG
Analog CCD cameras perform well across a variety of lighting conditions and manage motion well. Analog cameras do not have capabilities above the NTSC/PAL standards. As analog compresses the video in the DVR there are more hardware and software resources available to provide increased video quality and frame rate.
Analog cameras transmit the video image to the DVR uncompressed where it can be viewed live with no latency pre-compression.
