Glossary

Alarm outputs

Number of alarm outputs provided in the design of the call panel.

This is a contact used to connect external devices, such as an alarm or security system, to trigger an alert or other security functions under certain conditions. This output can be used to send a signal to the security system, activate external sirens, or other alert devices in alarm situations, for example, during an attempted unauthorized access. The alarm output helps enhance security by ensuring timely responses to potential threats or incidents.

Operating temperature

The range of air temperatures in which the call panel maintains normal performance.

Outdoor panels installed outdoors and in unheated rooms are subject to the greatest temperature fluctuations, therefore, it is with this installation that this parameter should be paid special attention. At the same time, we note that even the most “heat-resistant” models must be protected from sunlight. If the conditions in the room are comfortable for people all year round, then they will be quite normal for the call panel, in such cases you can not look at the operating temperature at all.

Horizontal viewing angle

The horizontal viewing angle provided by the camera on the entry panel of the intercom.

This parameter has a double meaning: other things being equal, a wider field of view allows you to cover more space, but reduces the size of individual objects in the frame. So it’s worth choosing according to this indicator, taking into account what is more important for you — good visibility on the sides or an additional degree of increase. As for specific values, in modern outdoor panels they can vary from 50° (directional cameras) to 166° (ultra wide-angle lenses with a minimum of dead zones on the sides).

Vertical viewing angle

The vertical size of the space covered by the video panel camera, in other words, the angle between the two lines connecting the lens with the top and bottom edges of the viewed scene. The meaning of viewing angles is described in detail above in paragraph “Viewing angles horizontally”; we only note that they are usually smaller vertically than horizontally, and in many models this parameter is not indicated at all due to its secondary importance.

Diagonal viewing angle

This value characterizes the angle of coverage of the image diagonally, this figure is usually slightly larger than the horizontal angle, this is due to the fact that the frame that we see is already in a rectangular form, usually with an aspect ratio of 3 to 4 or 16 to 9, and part of the frame can be circumcised. This indicator, along with the horizontal and vertical viewing angles, allows you to estimate from what distance the visibility of the interlocutor will be acceptable.
