PT-Series HD Camera Installation
Lens Heaters
The lens heaters are intended to provide lens de-fogging and de-icing in the event of:
• A power interruption which disables the camera for an extended period, and
• Freezing rain which fully covers the lens and obstructs the image.
The PT-Series HD cameras are shipped from the factory with the lens heaters enabled. The lens
heaters are configured to dynamically maintain the camera window at a constant temperature.
The lens heaters may be turned on manually from the Live Video web page (De-Ice button). Refer to
. The heaters, when turned on manually, will run for approximately one
hour unless turned off either by the user (De-Ice button) or the thermostat control.
1.6.3 Video Connections
The analog video connections on the back of the camera are BNC connectors. The camera also
provides an RCA video connector that can be used to temporarily monitor the daylight camera
(DLTV) video output.
The video cables used should be rated as RG59U or better to ensure a quality video signal.
Note
1.6.4 Ethernet Connection
The cable gland seal is designed for use with shielded Ethernet cable.
Note
1.6.5 Serial Connection
For serial communications, it is necessary to set the parameters such as the signaling standard (RS-
232 or RS-422), baud rate, number of stop bits, parity and so on. It is also necessary to select the
communication protocol used (either Pelco D or Bosch) and the camera address. By default, the
serial interface uses Pelco D, RS-422 standard, 9600 baud rate, 8/1/none, and address 1.
Note
Connect the wires of the serial cable as show in . When using the RS-422
standard, ensure the transmit pair of the camera goes to the receive pair of the other device, and
vice versa.
Note
Insert the cable through the cable glands on the enclosure before terminating and connecting them.
In general, the terminated connectors will not fit through the cable gland. If terminated, it is possible
to make a clean and singular cut in the gland seal to install the cable into the gland seal.

Typical Bosch systems operate using a biphase connection. FLIR cameras do not accept biphase
signals directly. It may be necessary to install a biphase converter in order to use the Bosch protocol.
The terminal blocks for serial connections will accept a maximum 20 AWG wire size.
