System Scheme
The checkpoint camera is mainly used for road surveillance. Before the site survey and
installation, ensure that the installation environment meets the following requirements:
Illumination: at least 50 lux (can be measured by using an illuminometer).
•The outdoor illuminanceis too high under direct sunlight.Therefore, try to avoid direct sunlight.
•The illuminanceat urban roads at night is insufficient. To clearly capture images at night, you need to install
external illuminators for the camera.
Light direction: even illumination, no backlight or highlight
Lane requirements:
•Ensure that the path within 50 m in front of and behind the camera is a straight line. Ensure that there are no
traffic lights within 200 m in front of or behind the camera. Otherwise, vehicles may queue up and the camera
may be unable to capture license plates of subsequent vehicles.
•At some intersections, there are multiplelanes for diverting vehicles with different drivingdirections. In this
case, it is recommended that cameras be installed a little bit away from these intersections and be installed in
a location with fewer lanes to facilitate license plate capture and recognition.
•Avoid bus stations in the field of view. Vehicles may block each other at bus stations, which affects license
plate capture and recognition.
•There are street lamps on the test site. Avoid sodium lamps and strobe or flash lights that are not controlled by
cameras within the camera's field of view.
•Keep the camera away from irrelevant objects such as leaves and billboards, as well as highlyreflective
objects such as glasses.
Others:
•Ensure that the pole or beam can sustain at least four times the total weight of the camera, housing, and
mount.
•Take waterproofing measures to prevent any liquid from flowing into the device.

Install the Camera
Erect the pole and install the camera above the center of the scene according to the system scheme.
1. Install the universal joint on the pole mount, adjust the horizontal and vertical shooting angles of the camera, and
tighten all screws on the universal joint.
2. Install the camera on the universal joint and tighten the screws. By loosening the screws (indicated by a, b, and c)
on the universal joint, you can adjust the tilt angle, horizontal angle, and vertical angle of the camera.
3. Thread the hose clamps through the installation holes on the pole mount, place them around the beam, and
tighten them up.

Install and Adjust the Lens
1. Before the operation, ensure that the
camera is powered off. Loosen the knobs
on the aperture ring and focus ring and fix
the lens into the lens base. During this
process, ensure that the knobs on the lens
are on the top.
2. Loosen the screws on the lens base,
and slowly push the lens and the base
towards the viewing window until the gap
between the front end of the lens and the
inner side of the viewing window is 1 mm at
most. Then tighten the screws on the base.
In scenarios with strong light sources, you
are advised to push the lens and base
along the guide rail to the end.
3. Power on the camera. Adjust the aperture for optimal image brightness.
Loosen the knob on the aperture ring and adjust the aperture to F1.8 to
F2.2. Then use the Philips screwdriver to tighten the screws on the side of
the lens.
4. Adjust the focus ring for optimal image clarity. Loosen the knob on the
focus ring (labeled Near/Far or ∞), rotate the focus ring back and forth to
generate images with optimal quality. Then use the Philips screwdriver to
tighten the screws on the side of the lens. It is recommended that a
vehicle be parked at the capture position. Then check the license plate
clarity in the image to determine whether the lens is properly adjusted.
5. View live video from the
camera. If the brightness is too
high, loosen the knob on the
aperture ring, decrease the
aperture to obtain your desired
video effect. Then use the Philips
screwdriver to tighten the screws
on the side of the lens.

Install Illuminators——Strobe Light and Flash Light (2）
1. Connect illuminators to the camera based on the pigtail type of the illuminators. The following shows how to connect illuminators to
an X series camera (same as the cable connection mode for M series cameras with only three TTL interfaces): Connect Huawei
flash lights to LED interfaces (F1-F4) and Huawei strobe lights to TTL interfaces (T1-T4). For flash lights provided by other vendors,
choose the interfaces to connect to based on the Boolean value or level of the flash lights.
Note:
•If the signal control cable of the illuminator is not clearly identified as alevel output or a Booleanvalue cable, checkthe illuminator instructions or consult the illuminator
supplier to confirmthe signal control cable type.
•An X series ITScamera canconnect to a maximum of eight external illuminators, and an M seriesITS cameracan connect to a maximum of sevenexternal illuminators.
•The TTL interfaceof Huawei checkpoint cameras canidentify only level ranging from 0 V to 5 V.
2. Check the connection status of the illuminators.After the illuminators are installed, log in to the camera web system, choose
Settings > Snapshot > Illuminator Settings and set Work mode to On under External Light Settings. Go to the View page and
click Manual to manually take a snapshot, or wait for vehicles to pass. Check whether the flash light flashes duringimage capture.
For Huawei strobe lights, set the frequency to 100 Hz.
On the cameraweb page,T and F
