Frequently Asked Questions

1.IP camera
An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which unlike analog closed circuit television (CCTV) cameras can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term "IP camera" or "netcam" is usually applied only to those used for surveillance.

2.POE(Power over Ethernet)
Power over Ethernet or PoE technology describes a system to pass electrical power safely, along with data, on Ethernet cabling. The IEEE standard for PoE requires category 5 cable or higher for high power levels, but can operate with category 3 cable if less power is required.[1] Power is supplied in common mode over two or more of the differential pairs of wires found in the Ethernet cables and comes from a power supply within a PoE-enabled networking device such as an Ethernet switch or can be injected into a cable run with a midspan power supply.

3.1080P HD
1080p is a set of HDTV high-definition video modes that are characterized by 1080 horizontal lines of vertical resolution[1] and progressive scan, meaning the image is not interlaced as is the case with the 1080i display standard. The term assumes a widescreen aspect ratio of 16:9, thus implying a resolution of 1920 x 1080 (2.1 megapixels).

4. WDR(Wide dynamic range)
The wide dynamic range (WDR) function of a camera is intended to provide clear images even under back light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark.

5. Effio(Sony EFFIO HD CCTV Video Format)
Sony EFFIO HD CCTV Video Format is an uncompressed analog streaming video format used in for closed-circuit television especially used for crime prevention and video surveillance and monitoring. As of August 2012, little is known about the inner workings of the format. It does seem to be a version of the broadcast uncompressed streaming SDI, similar to HDCCTV, HDMI, and DVI.
