Digital CCTV (HD)

Closed-circuit television (CCTV) digital cameras & DVR

An IP/Digital camera, is a camera that digitizes and processes analogue images, encodes them internally, and then transmits the video information digitally over an Ethernet connection to a computer or similar device. An IP camera can have either a CMOS or a CCD sensor, and is available in the same styles as traditional surveillance cameras such as Pan/Tilt/Zoom, domes, bullets, box, infrared, covert, and wireless. Digital cameras are typically equipped with an embedded web server and can be accessed and controlled over any IP network such as a WAN, LAN, Intranet, or Internet. By utilizing a standard web browser or client software users can view an IP camera’s video output from any local or remote location.

Digital cameras combine the capabilities of a camera with some PC functionality, do not require a direct connection to a PC to operate, and can be placed anywhere within a network. Just like any other PC on the network, a Digital camera is a "network appliance". It has its own IP address, connects directly to a wired or wireless network and requires maintenance.

Digital cameras are Megapixel enabled giving High Definition (HD) output signals.  Digital cameras are connected to NVRs (Network Video Recorders) which are capable to record high bandwidth video signals, are also be connected to the network and provide remote viewing capabilities to a computer or even to a mobile device.

Analogue CCTV

Closed-circuit television (CCTV) analogue cameras & DVR

An analogue surveillance camera begins with a CCD sensor which converts the visible pictures to analoque PAL/SECAM video signals. Unlike IP cameras, analogue have no built-in web servers or encoders. These functions are implemented in the recording and/or control equipment, the DVR (Digital Video Recorders) which encode the data and store it for later viewing.  DVRs provide connection to the internet for remote viewing on computers and mobile devices. 

Analogue cameras come in diffrent shapes (cylinder, bullet, Dome cameras) and can be equipped with Infrared LEDs to enable night vision and various other features enabling best picture quality under difficult conditions.
