Climate Control
Monitoring of indoor climates includes heating, ventilating and air conditioning systems.
These systems are usually connected to computers via long serial cables. A more
convenient solution is if the building’s control systems are connected to a network via
AXIS 2490 Serial Servers. This enables remote access and monitoring from anywhere in
the network. Service engineers can also locate and identify errors. In some cases they’ll
even be able to solve the problem directly over the network, and even if they can’t, they’ll
know which equipment and spare parts are needed.
Pan/Tilt/Zoom (PTZ) Applications
As a person approaches a building, this is seen on a computer screen. An operator clicks on
the image and a camera redirects and zooms in. An enlarged image of the person is
displayed on the screen.
This is a realization of a Pan/zoom/tilt device and a camera connected to a network via
AXIS 2490 Serial Servers. The camera can be controlled by simply using a browser and
clicking on control buttons in the web page. Another alternative is to activate the proper
camera positions by using an image map of the area in question, as in the example above.
Wherever something interesting happens, you only need to click on the image. The PTZ
device will redirect the camera to the chosen spot.
