The HiRes Video Company

MxPEG: Method developed by MOBOTIX to compress and store image and video data with low

network load and high image quality. The MxPEG ActiveX control element allows video and audio

data from MOBOTIX cameras to be displayed in other applications (including Internet Explorer).

Network: A group of computers that are connected via various cables and share access to data

and devices such as printers and IP cameras.

PIR: Passive infrared sensor for motion detection.

PoE: Power over Ethernet. A technology for supplying network-enabled devices (for example, IP

cameras) with power via the Ethernet cable.

PTZ: Abbreviation for Pan/Tilt/Zoom. Refers to the movement of a video camera to the left and

right, up and down, and to the camera's ability to enlarge an image.

Resolution: Indicates the number of pixels used to produce an image. The more pixels an image

has, the more recognizable the details remain when the image is enlarged. The resolution is

expressed as the number of pixel columns by pixel rows or as a total number of pixels. A VGA

image has 640 columns and 480 rows (640x480 pixels), which equals 307,200 pixels or approxi-

mately 0.3 megapixels.

RFID: Radio frequency identiﬁcation.

Router: Network device that connects multiple networks with one another. The router establishes

a physical connection between the devices in dierent networks (like a hub), analyzes the relevant

data packets and forwards ("routes") these packets to the correct target network.

Search: Monitoring of recordings or searching for a particular event.

SIP: Session Initiation Protocol. Network protocol for setting up, controlling and terminating a

communication connection via a computer network. SIP is frequently used in conjunction with

IP telephony.

Switch: Hardware used to connect multiple network devices (computers, cameras, printers, etc.)

within a network. A PoE switch can also supply the cameras with power over an Ethernet cable.

Transponder: A transponder is a device used for wireless communication (for example, as a key

tag or a check card). The device detects the incoming signal and automatically responds to it or

forwards it. The term "transponder" is made up of the terms "transmitter" and "responder." Passive

transponders do not require their own power source, but they only work over short distances.

VoIP: Voice over IP. Telephony using computer networks.

WLAN: Wireless Local Area Network. Used to provide Internet connections without the need for

cables.
