WARNING - EAR Controlled Technical Data
Installation
Caution!
Except as described in this manual, do not open the Saros Dome camera for any reason. Damage to
the camera can occur as the result of careless handling or electrostatic discharge (ESD). Always
handle the camera with care to avoid damage to electrostatic-sensitive components.
Prior to making any connections, ensure the power supply or circuit breaker is switched off.
Be careful not to leave fingerprints on the Saros Dome camera’s infrared optics.
Operating the camera outside of the specified input voltage range or the specified operating
tem
per
ature range can cause permanent damage.
1.2 Installation Overview
The Saros Dome camera can be used for indoor or outdoor security applications.
1.2.1 Camera Connections
The camera can be powered using Power over Ethernet (PoE) or with a conve
ntional 24 Vac or 12
Vdc power supply. To be powered using PoE, the camera must be connected to either a PoE switch
or a standalone PoE power supply (also called a PoE injector). The maximum Ethernet cable run is
100 meters, including the PoE power supply. For installations using PoE power and IP video, a
single Ethernet cable is the only required connection. The Saros Dome camera is a Powered Device
compliant with the IEEE 802.3af-2003 standard.
Input/Output
The camera can receive one input sign
al and
can provide one output signal. By default, the signals
are configured for normally open alarm switch circuits. Refer to Power & I/O Connector.
Input Signal—Whe
n an external alarm device closes a switch to complete the circuit for the
camera, an input signal is generated to cause an action or an alarm when configured on the Alarm
Page. See also Input/Output (I/O) Page.
Output Signal—Whe
n an output alarm is generated, the camera closes its internal switch to
complete the circuit for the receiving device.
