1.5 Removing the Cover
In order to access the electrical 
connections and install the cables, it is 
necessary to temporarily remove the top 
cover of the camera housing. The top 
cover of the camera is held in place with 
four 3 mm hex screws. The screws are 
accessible through slots in the sunshield, 
so the sunshield does not need to be 
removed from the top cover.
Use a 3 mm hex key to loosen the four 
captive screws, exposing the connections 
inside the camera enclosure. There is a 
grounding wire connected inside the case 
to the top cover, as shown. If it (or any of 
the grounding wires) is temporarily 
disconnected during the installation, it 
must be reconnected to ensure proper 
grounding of the camera.
Caution!
Replace the cover and tighten the four 3 mm hex screws to 1.8 n-m (16.0 in-lbs).
1.6 Camera Connections
Refer to Ta b l e 1-1 for a description of these camera connections.
When replacing the cover, ensure that the ground wire between the cover and the camera body is 
completely inside the o-ring groove. If the wire is pinched between the cover and body the camera 
is not sealed against water ingress and can be damaged.

1.6.1 Configuring the Lens Heater Jumper
The supplemental lens heater is intended to provide lens 
de-icing in the rare combination of:
• A power interruption which disables the cam-
era for an extended period, and 
• Freezing rain which fully covers the lens and 
obstructs the image. 
FLIR recommends that the supplemental lens heater be 
enabled only when the installation environment is such that 
this combination of conditions is common. 
The FC-Series camera is shipped from the factory with the supplemental lens heater OFF (jumper 
pins 2 and 3). To enable the Supplemental Lens Heater, move the heater jumper to ON (jumper pins 1 
and 2). Proper operation of the Supplemental Lens Heater requires that the camera be powered by 24 
Vac, >16Vdc or POE+.
It is important to note that the supplemental lens heater is not required for operation in all cold 
temperatures. The system operates to specification and produces highest quality images without the 
Supplemental Lens Heater. Contact FLIR Technical Support for additional information (888-747-3547 
inside the US).

1.6.2 Analog Video Connections
The primary analog video connection of the camera is a BNC connector. Alternatively, the camera 
also provides an RCA analog video connector. Only one or the other connection should be used on a 
permanent basis to ensure adequate video quality. The RCA connection allows the installer to 
temporarily monitor the video output, without disconnecting the primary connection.
The video cable used should be rated as RG-59/U or better to ensure a quality video signal. 
Note
1.6.3 Connecting Power
The camera can be powered with a conventional ac or dc power 
supply, rather than PoE+. Prior to making any connections, 
ensure the power supply or circuit breaker is switched off. 
The power cable supplied by the installer must use wires that are sufficient size gauge for the supply 
voltage and length of the cable run, to ensure adequate current carrying capacity (18 AWG 
recommended for most installations). Always follow local building/safety codes.
Note  
The power connector plug may be removed for cable installation. After the plug is reattached to the 
board, re-tighten the screw terminals.
The camera itself does not have an on/off switch. Generally the FC-Series camera may be connected 
to a circuit breaker and the circuit breaker will be used to apply or remove power to the camera. If 
power is supplied to it, the camera will be powered on and operating.
Insert the cables through the cable glands on the enclosure before terminating and connecting them. 
In general, terminated connectors will not fit through the cable gland. If a terminated cable is required, 
it is possible to make a clean and singular cut in the gland seal to install the cable into the gland seal.

1.6.4 Ethernet
Connect a shielded cat5e/6 Ethernet cable to the 
RJ-45 jack. If using PoE+ to supply power to the 
camera, connect the other end of the Ethernet to a 
PoE+ switch or PoE+ injector. Otherwise connect 
the Ethernet to a network switch.
1.6.5 GPIO Connections
Input Signal—The camera can receive an 
external input signal on accessory connector J8 
pins 4 and 5 when these pins are connected by an 
external switch closure. Pin 5 is connected to the 
camera’s internal +5V power supply and must not 
be directly connected to chassis ground. Pin 4 is 
connected to the internal digital ground. 
While protection for static discharge has been 
placed on these pins, care should be used in 
making connections to the pins to avoid 
connections to other voltages or power sources 
outside the camera. 
Output Signal—The camera can provide a 
contact closure output signal on accessory 
connector J8 pins 2 and 3 when an external 
voltage is supplied to these pins. When open the 
resistance between pins 2 and 3 is greater than 
100 K ohm. When closed the resistance between 
pins 2 and 3 is less than 200 ohm. The maximum 
recommended peak voltage between the pins is 6 
volts. The maximum recommended current 
allowed between the pins is 30 mA (0.03 A).

1.6.6 Camera Grounding
Ensure the camera is properly grounded. Failure to 
properly ground the camera can lead to permanent 
damage to the camera. Typical to good grounding 
practices, the camera chassis ground should be 
connected to the lowest resistance path possible. 
The camera has an external ground connection on 
the outside back of the camera. FLIR requires a 
grounding strap anchored to the grounding lug and 
connected to the nearest earth-grounding point. 
If, during installation, any ground connections 
inside the camera are disconnected, they should 
be reconnected prior to closing the camera. 
1.7 Rear Access Cable Gland Sealing
Proper installation of cable sealing gland and use of appropriate elastomer inserts is critical to long 
term reliability. Cables enter the rear of the camera mount enclosure through a liquid-tight 
compression gland. 
Leave the gland nut loosened until all cable installation has been completed, and ensure the 
manufacturer’s recommended cable bend radius is observed within the enclosure. Do not forget to 
tighten the cable gland seal nut to ensure a watertight seal and provide strain relief for cables. 
Cable Gland Seal Inserts
The FC-Series camera comes with a single 3/4” NPT cable gland installed in the camera, with a four-
hole gland seal insert. The gland includes a sealing washer and is secured to the camera with a nut 
on the inside of the enclosure. The gland insert has one hole for the RG-59/U analog video cable (the 
larger hole) and three more for a power cable, Ethernet cable, and an accessory cable (not used at 
this time). 
Any of the holes which are not used for cables should be filled with one 
of the hole plugs (supplied). Install the cables through the cable gland 
so that the cables line up with the connections inside the camera. 
Note
To ensure a water tight seal when using the supplied rear cable gland, cable dimensions must be 
within the minimum and maximum as described in 
Ta b l e 1-4.
If non-standard cable diameters are used, an appropriate cable gland and insert should be used to fit 
the desired cable and to fit the hole in the enclosure. FLIR Systems, Inc. does not provide cable gland 
inserts other than the insert supplied with the system. 
If a replacement is used, inspect and install the gland fitting in the back cover with suitable leak seal or 
sealant and tighten to ensure water tight fittings. To fit the 1.050 in. (26.7 mm) hole in the enclosure, 
the thread size should be 3/4” NPT or M25. The gland should be installed with a sealing washer (for 
example, Heyco PN 3261 or equivalent) between the gland and the external surface of the enclosure.
Insert the cables through the cable glands on the enclosure before terminating and connecting them. 
In general, terminated connectors will not fit through the cable gland. If a terminated cable is required, 
it is possible to make a clean and singular cut in the gland seal to install the cable into the gland seal.

1.8 Concealed Cable Mount Accessory
Do not route cables through the bottom of the camera unless the concealed cable wall mount (PN 
4129742) is used. The wall mount is specifically designed for the camera and allows the opening to 
seal properly. When using the concealed cable wall mount, cable dimensions must be within the 
minimum and maximum as described in 
Ta b l e 1-5.
Proper installation of the seal plate and panel mount gland seals is critical to long term reliability. 
Cables enter the bottom of the camera enclosure through the seal plate and panel mount glands. Be 
sure to insert each cable through its panel mount gland on the seal plate before terminating them 
(connectors will not fit through the gland). Ensure the manufacturer’s recommended cable bend 
radius is not exceeded within the enclosure.
Prepare the Camera
Step 1 Use a 3 mm hex key to loosen the four captive screws and remove the top cover as 
described above. 
Step 2 Remove the rear cable gland and replace it with the cable gland plug. Use the gasket and 
nut that were removed with the cable gland.
Step 3 Use a 3 mm hex key to 
loosen the four captive 
screws and remove the 
seal plate, o-ring, and 
plug.

Step 4 Install the wall mount (PN 4129742) to the wall 
and pull the cable(s) through the mount. Cut a 
small cross-slit in the black mount gasket and 
push the cable(s) through the gasket. Pull the 
cable(s) through the opening in the bottom of 
the camera. A single Ethernet cable is shown 
in the images. 
Step 5 Secure the camera to the mount using four M5 
x 0.8 threaded fasteners to the bottom of the 
camera. Use Loctite 222 low strength thread 
locker for the mount fasteners.
Step 6 As needed, clean the o-ring and the o-ring 
groove in the bottom of the camera using isotropy 
alcohol and press the o-ring into its groove.
Step 7 For each cable, punch hole in the center of a gland 
seal from the top using the 3 mm hex key. Insert the 
cable from the bottom though the hole.
Step 8 Place the gland plate back into position and tighten 
the four 3 mm captive screws using a torque value 
of 1.8 n-m (16.0 in-lbs).
Step 9 Check the length of each cable to ensure an 
appropriate bend radius and terminate the cable.
Step 10 Push the cable back through the gland seal so that 
the seal is extended down not up, as shown in the 
illustration below. 
Step 11 Connect the cables as indicated in Figure 1-7 on page 1-7. Ensure that any ground wire 
that was removed during installation is reconnected. Replace the cover and tighten the four 
3 mm hex screws to 1.8 n-m (16.0 in-lbs).
Caution!
Step 12 Using the hex key that is included with the concealed cable mount, loosen the ball joint on 
the bottom of the mount, position the camera as required, and then re-tighten the ball joint.
When replacing the cover, make sure the ground wire between the cover and the camera body is 
completely inside the o-ring groove. If the wire is pinched between the cover and the base, the 
camera will not be sealed against water ingress and could be damaged.
