Opening Contact

On moveable building elements (window, door), a magnetic contact (Reed contact) is

attached to the ﬁxed part, and a magnet is attached to the moveable part. When the

door is closed, the magnet is located in direct proximity to the contact and keeps it closed.

When the door is opened, the magnet is removed and the contact opens.

PIR Sensor

Passive infrared sensor for motion detection.

Pixel (Picture Element)

One of the many tiny image dots that make up a digital image. Each pixel determines

through its color and intensity a tiny part of the overall image.

Perimeter Protection

Perimeter protection (outdoor protection) serves to protect an object through measures

in its surroundings or in the surrounding free space, usually up to and including the

site boundary line. This includes mechanical/building measures (perimeter security),

electronic/detection measures, and/or organizational/stang measures (perimeter

surveillance).

PoE (Power over Ethernet)

Power-over-Ethernet enables power to be supplied to a network device using the same

cable that is used for connection to the network. This is particularly beneﬁcial in the case

of IP and remote surveillance in places where laying a power cable from the nearest outlet

would be too costly or time-consuming.

Product Liability

Under the German Product Liability Act, the manufacturer or retailer is liable for the product

that they have brought to market. Claims are only possible when the product is used

in accordance with its intended use and there is no evidence of misuse. The technical

speciﬁcations and information described in the T24 System Manual must be observed.

Otherwise, the manufacturer is released from their product liability in accordance with

the German Product Liability Act.

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), which equals 307,200 pixels

or approximately 0.3 megapixels. The T24 has 3.1 megapixels.
