Capture Button
Use this button to capture snapshots (in JPEG format) or 
video clips (in AVI format). The files are stored on the 
integrated SD card. AVI files are viewable via the FLIR Viewer Utility 
included on the BHS-Series Bi-Ocular resource CD.
• Momentarily pressing the button captures a single snapshot.
• Pressing and holding the capture button for three seconds puts 
the camera in video record state. The video record icon should be 
displayed. The button may now be released and the camera will 
continue to record until the capture button is pressed again. The 
video file is then written to the SD card in AVI format. 
Twenty-five seconds of video requires about one megabyte (MB) of 
storage on the SD card. The image and video files must be transferred 
to a computer for viewing.
Note
• If the camera is not licensed for this 
feature, this message will be shown 
in the display.
• If an SD card is not installed, this 
message will be shown in the 
display and no image will be stored.
• If the SD card is full, a warning will 
be shown in the display and the 
image will not be stored.
Note
The images must be transferred to a computer via the USB cable, 
or the SD card can be temporarily removed from the camera and 
inserted in a card reader.
The stored image will include the thermal image, time and date 
information, and the FLIR logo. Other icons seen in the display are 
not stored on the saved image.

White/Black Hot Button
Use this button to toggle between the two video options. In 
the default White Hot mode, hotter objects appear as white 
or light grey. In the Black Hot mode, hotter objects appear as 
black or dark grey. While white hot is the most commonly

imagery, black hot can often enhance contrast of certain objects or 
provide better visual perspective in some conditions. 
When switching between modes, the appropriate 
icon is displayed for approximately 3 seconds.

brightness. Each press of the button advances to the next 
level of brightness.

3–7 Batteries
Your BHS-Series Bi-Ocular camera is equipped with a sophisticated 
power system that accommodates a wide variety of AA battery types. 
This includes rechargeable and non-rechargeable batteries.
The camera is optimized for operation with the 2700 mAh 
rechargeable NiMh batteries that were supplied with your camera. It 
is recommended that you use these batteries in all but emergency 
situations. 
Note
Battery Status Indicator–While the camera 
is On, a battery status indicator is always 
shown in the corner of the display image. This 
indicator provides an estimation of the 
remaining battery charge. 
Note
Using Non-Rechargeable Batteries –The BHS-Series Bi-Ocular 
camera allows Alkaline non-rechargeable batteries to be used. When 
non-rechargeable batteries are installed, connecting the Hot Shoe to 
a power source will power the camera from the power source and the 
battery charging circuitry will be disabled.
Note
Low Battery Auto-Shutdown–When the batteries are almost fully 
depleted the camera will automatically initiate a shutdown process.
Replacement batteries are available online from FLIR Commercial 
Systems, Inc.
If non-rechargable batteries are installed the battery indication 
may not be accurate.
When using Alkaline batteries, operating battery life is reduced to 
approximately 1.5 hours.

3–9 Auto-Standby Operation
Auto-Standby is a feature of the BHS-Series Bi-Ocular camera that 
helps to guard against draining the batteries prematurely by 
inadvertently leaving the camera on. Auto-Standby puts the camera 
into the Standby state if the following three conditions are met:
• The camera is in the On state.
•The Auto-Standby switch (STBY) is set to ON.
• No buttons have been pressed for three minutes.
Once these conditions are met you will 
see the following message in the display 
and the camera will enter the Standby 
state after the countdown is finished:
Press any button during this countdown to terminate Auto-Standby 
and resume normal operation. 
Note
Auto-Standby Switch
Unattended operation of the camera 
requires disabling Auto-Standby. 
Select OFF to turn off Auto-Standby.
