Opening Switch

On movable building elements such as doors and windows, a magnetic switch (Reed switch)

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 switch and keeps it closed.

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

Perimeter Protection

Perimeter protection (outdoor area protection) serves to protect a property through measures

installed in its vicinity, usually including the property boundary line. This includes mechanical/

building measures (perimeter security), electronic/detection measures and/or organizational/

stang measures (perimeter surveillance).

PIR Sensor

Passive infrared sensor for motion detection.

Pixel (Picture Element)

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

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

PoE (Power-over-Ethernet)

Power-over-Ethernet enables network devices to be powered via the same cable that

provides the network connection. 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.
