CCTV Surveillance System
DVR Systems
The 2 camera security systems on this page include (2) 1080p HD CCTV cameras, 4 channel CCTV DVR (up-gradable to 8 and 16 channel), pre-made Siamese cables, and camera power supplies. Customers can add-on an optional flat screen monitor. The monitor is optional because these DVRs have a VGA and HDMI video output that can be used with any common computer monitor or television with those types of inputs. Other optional system upgrades are spools of RG59 Siamese cable instead of premade Siamese cables and multi-port power supply boxes instead of individual power supplies for the CCTV cameras. These systems include our best selling hybrid CCTV / HD CCTV DVRs. They have been a favorite among our customers over the last 5 years because of the easy to use interface, Windows and Mac remote access support, and outstanding free mobile apps for iOS and Android mobile and tablet devices. We offer 2 camera systems so that customers can get started with securing their home or business and add additional cameras when needed. The systems on this page include some of our best selling HD security cameras, however, we can mix and match any combination of cameras in any quantity to build a custom surveillance system for your exact needs.
Cameras
A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens/convex lens and an image is recorded on a light-sensitive medium(mainly a transition metal-halide). A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed. A movie camera or a video camera operates similarly to a still camera, except it records a series of static images in rapid succession, commonly at a rate of 24 frames per second. When the images are combined and displayed in order, the illusion of motion is achieved.
