CCTV is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
The system 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 are based on digital cameras on an IP network providing video in color, high-resolution displays and can facilitate the ability to zoom in on an image or track something (or someone) among their features.
Red Fox Systems Cameras include:
- Analog cameras ( - Cameras on a modern analog CCTV system send their video in the traditional base band format over coax or UTP cabling back to a digital video recorder (DVR). Here, video is digitized and stored on hard drives. Most modern DVRs are a network device, and as such can be accessed remotely from the LAN, or with the proper configuration, from across a WAN or the internet. They are comparatively lower cost and have superior compatibility – It is much easier to mix and match cameras and incorporate existing camera equipment into older surveillance systems if you use analog versions.
- Digital IP cameras - IP video cameras broadcast their video as a digital stream over an IP network. Like an analog system, video is recorded on hard drives, but since the video is an IP stream straight from the camera, there is more flexibility as to how and where that video is recorded. The DVR is replaced with an NVR (network video recorder), which in some cases is just software since it doesn't need to convert analog to digital. Other benefits include high resolution and wireless surveillance.
- PTZ (Pan, Tilt, Zoom) cameras - A PTZ camera is a camera with pan, tilt, and zoom functionality. These movements can be manually controlled by using monitoring software or a joy stick, or automatically set up using camera management software. Being able to move the camera necessary by a security guard allows your security staff to respond quickly to events they spot with the surveillance system.
How PTZ Works?
Panning - The camera can swivel to the left and right, allowing it to have a wide area of coverage. Pan can range from a complete 360 circle to smaller areas.
Tilting -The camera can tilt up and down, giving wide vertical range of coverage. The amount of tilt will vary by camera model, but it goes up to 180 degrees.
Zooming - Optical zoom physically adjusts the camera lens, changing the focal length to zoom in and out; this allows the camera to maintain image quality. The amount of optical zoom is expressed as #x, such as 18x, and represents how much the camera can zoom (change the lens focal length)Digital zoom increases focus magnification of the image area using software, often resulting in pixilated images when zoomed too far.
