CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation “closed-circuit” to indicate that access to their content is limited by design only to those able to see it. Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera’s associated speakers. IP surveillance is a digitized and networked version of closed-circuit television (CCTV). In an IP surveillance system, an IP camera records video footage and the resulting content is distributed over an IP (Internet protocol) network. Digitization offers a number of benefits over traditional analog CCTV, including: • Improved search capability. • Greater ease of use. • Better quality images and no degradation of content over time. • The ability to record and play simultaneously. • The ability to compress content for improved storage. Adding networking capability to digital CCTV provides additional benefits, including: • Improved ability for remote viewing and control. Anyone on the network can potentially see video from any camera connected to the network. Our HD security cameras use HD-CVI technology to deliver image quality that is far superior to traditional analog CCTV. HD cameras are a cost-effective video surveillance solution that is easy to install and integrate with existing CCTV systems.
