When connected, find the special app,
Cam802 , and open it to observe the
real-time images in the thermal imager.
Analog video: is a switch for transmitting
the videos on a thermal imager and must
be switched on for head-mounted,
wireless, or wired video transmission.
Connection steps for wired transmission
(common display as an example):
①Switch on the analog video;
②Plug the special cable into the thermal
imager as described in chapter 5.3;
③Plug the BNC connector of the cable
into the video input port of the display;
④Adjust the display mode of the display
so that images can be shown on the
display properly;
The system can carry out automatic
detection. When the battery is running
low, the image transmission will not be
enabled, and a prompt will appear on the
display; when the temperature is
relatively low, the operating voltage will
go down, and the time of image
transmission will be shortened due to
battery performance.
Figure 8 shows the image transmission
interface:
Figure 8 Image Transmission Adjustment
6.3.4 Image Transmission
Image transmission is to transmit the
videos on a thermal imager to other
devices, through a wired or wireless
approach, for simultaneous observation,
coordinated command, and quick directions.
It can be performed through head-mounted
transmission, wireless transmission, or
analog videos (disabled by default; must
be enabled to use after the device is
being powered on);
Head-mounted transmission: transmits
images to head-mounted devices. This
option currently supports Jerry-F products
and can transmit videos on a thermal
imager to a Jerry-F product in real time.
For steps to connect to a Jerry-F product,
see the user manual for Jerry-F. (Before
connecting to a Jerry-F product, turn on
its pairing switch. When the head-mount-
ed transmission is switched on, the
thermal imager pairs with the Jerry-F
product. The process lasts 30 seconds.
After that, operate by following the
instructions on the thermal imager.)
Wireless transmission: transmits information
on a thermal imager screen to cellphones,
tablets, computers, or other devices with
a Wi-Fi module (installation of the special
app required) to facilitate observation
and monitoring.
Connection steps for wireless transmission
(cellphone as an example):
①Switch on the wireless transmission;
②Switch on the analog video;
③Turn on Wi-Fi on the cellphone. Search
and connect to the Wi-Fi network with a
name containing "WIFIV_" (the default
password is "12345678" and you cannot
change it);

④Palette (Black Hot, White Hot, Red Hot,
Rainbow, and Red Face)
The Palette includes five modes: Black
Hot, White Hot, Red Hot, Rainbow, and
Red Face. Different palette highlights
distinct target colors and suits different
statuses. The default status is White Hot
mode, but you can switch among
different modes as required.
⑤Enhancement (default: On)
⑥Filter (default: On)
Enabling the image enhancement and
filter can enhance image details, refining
the image. The two functions are
enabled by default.
