2.4 Camera Installation
The camera unit, Part No. 9135210E, can be built into any 2N® Helios basic unit
during installation or as an option to be added later. You can also use the camera unit
in combination with any Vandal resistant panel. It is a colour CCD camera with high
resolution of 420 TV rows, with a monochrome night mode (infrared backlight hidden
under the nameplates), and has a wide-angle pin-hole lens (90º diagonally) and a
tilting hinge for manual direction adjustment.
The camera has a PAL composite output and can be connected to any TV display (e.g.
Part No. 9134147 - 7" TFT LCD), or a video server (Part No. 9134137, MPEG4 LAN
video server). A coaxial or twisted cable can be used for connection.
A sight glass is included in the delivery, which replaces the non-transparent 2N®
Helios basic unit sight glass imitation. To install the camera, follow the instructions
that come with it.
Warning
 To install the camera, use the stabilised 12 V dc power supply. To get a
suitable (12V / 2A) one, order Part No. 91341481E.
