6. Filter box installation

For a permanent installation, the filter box should be screwed onto the panel board by means of the 
feed through 

camera connector

 (see figure 2). Figure 3 illustrates the recommended configuration: 

A 12 mm through hole in the panel board is required. 

The 

camera connector

 is guided through this hole.

The camera connector provides the ground connection to the shielding of the MR cabinet.

For temporary use, the camera cable can be brought into the MR cabinet by other means, e.g. 
through a service entry hole (“waveguide”). In this case, an additional grounding cable should be 
used to connect the camera connector to the shield panel grounding. The camera connector must 
completely protrude into the MR cabinet and the video cable must not jut out.

7. Connection of power supply, light intensity adjustment

The power for the camera is transmitted via the video cable. Therefore, the power supply is 
connected to the filter box (see figure 4). Next to the video connector is a green “active” signal 
which shines when the device is powered and the LED on the front side of the camera is turned on. 
By pushing the button of the “active” signal the LED can be switched off. The intensity of the LED 
light can be adjusted by means of a potentiometer at the filter box.

7.1. Eye safety

The infrared LED in the camera is eye-safe. The peak wavelength is 950 nm. We recommend to keep
a distance between the light source and the subject's eye of 50 mm or more. With the white-light 
LED you should avoid to shine directly in the eye. Please be aware that the lid-closing reflex of 
babies can be unincisive.
