Network: A group of end devices, such as computers, that are connected via various cables

and share access to data and devices such as printers and IP cameras.

PIR sensor: 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×480), which equals 307,200pixels or

approximately 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 (door) 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 (Wi-Fi): Wireless local area network connection.
