Important Safeguards and Warnings
This section introduces content covering the proper handling of the device, hazard prevention, and
prevention of property damage. Read carefully before using the device, comply with the guidelines
when using it.
Transportation Requirements
Transport the device under allowed humidity and temperature conditions.
Pack the device with packaging provided by its manufacturer or packaging of the same quality
before transporting it.
Do not place heavy stress on the device, violently vibrate or immerse it in liquid during
transportation.
Storage Requirements
Store the device under allowed humidity and temperature conditions.
Do not place the device in a humid, dusty, extremely hot or cold site that has strong
electromagnetic radiation or unstable illumination.
Do not place heavy stress on the device, violently vibrate or immerse it in liquid during storage.
Installation Requirements
Strictly comply with the local electrical safety code and standards, and check whether the power
supply is correct before operating the device.
Please follow the electrical requirements to power the device.
When selecting the power adapter, the power supply must conform to the requirements of
ES1 in IEC 62368-1 standard and be no higher than PS2. Please note that the power supply
requirements are subject to the device label.
We recommend using the power adapter provided with the device.
Do not connect the device to two or more kinds of power supplies, unless otherwise specified, to
avoid damage to the device.
The device must be installed in a location that only professionals can access, to avoid the risk of
non-professionals becoming injured from accessing the area while the device is working.
Professionals must have full knowledge of the safeguards and warnings of using the device.

Quick Start Guide
IV
Do not place heavy stress on the device, violently vibrate or immerse it in liquid during installation.
An emergency disconnect device must be installed during installation and wiring at a readily
accessible location for emergency power cut-off.
We recommend you use the device with a lightning protection device for stronger protection
against lightning. For outdoor scenarios, strictly comply with the lightning protection regulations.
Ground the function earthing portion of the device to improve its reliability (certain models
are not equipped with earthing holes). The device is a class I electrical appliance. Make sure that
the power supply of the device is connected to a power socket with protective earthing.
The dome cover is an optical component. Do not directly touch or wipe the surface of the cover
during installation.
Operation Requirements
The cover must not be opened while the device is powered on.
Do not touch the heat dissipation component of the device to avoid the risk of getting burnt.
Use the device under allowed humidity and temperature conditions.
Do not aim the device at strong light sources (such as lamplight, and sunlight) when focusing it,
to avoid reducing the lifespan of the CMOS sensor, and causing overbrightness and flickering.
When using a laser beam device, avoid exposing the device surface to laser beam radiation.
Prevent liquid from flowing into the device to avoid damage to its internal components.
Protect indoor devices from rain and dampness to avoid electric shocks and fires breaking out.
Do not block the ventilation opening near the device to avoid heat accumulation.
Protect the line cord and wires from being walked on or squeezed particularly at plugs, power
sockets, and the point where they exit from the device.
Do not directly touch the photosensitive CMOS. Use an air blower to clean the dust or dirt on the
lens.
The dome cover is an optical component. Do not directly touch or wipe the surface of the cover
when using it.
There might be a risk of electrostatic discharge on the dome cover. Power off the device when
installing the cover after the camera finishes adjustment. Do not directly touch the cover and
make sure the cover is not exposed to other equipment or human bodies
Strengthen the protection of the network, device data and personal information. All necessary
safety measures to ensure the network security of the device must be taken, such as using strong
passwords, regularly changing your password, updating firmware to the latest version, and
isolating computer networks. For the IPC firmware of some previous versions, the ONVIF
password will not be automatically synchronized after the main password of the system has been
changed. You need to update the firmware or change the password manually.

Quick Start Guide
V
Maintenance Requirements
Strictly follow the instructions to disassemble the device. Non-professionals dismantling the
device can result in it leaking water or producing poor quality images. For a device that is required
to be disassembled before use, make sure the seal ring is flat and in the seal groove when putting
the cover back on. When you find condensed water forming on the lens or the desiccant becomes
green after you disassembled the device, contact after-sales service to replace the desiccant.
Desiccants might not be provided depending on the actual model.
Use the accessories suggested by the manufacturer. Installation and maintenance must be
performed by qualified professionals.
Do not directly touch the photosensitive CMOS. Use an air blower to clean the dust or dirt on the
lens. When it is necessary to clean the device, slightly wet a soft cloth with alcohol, and gently
wipe away the dirt.
Clean the device body with a soft dry cloth. If there are any stubborn stains, clean them away with
a soft cloth dipped in a neutral detergent, and then wipe the surface dry. Do not use volatile
solvents such as ethyl alcohol, benzene, diluent, or abrasive detergents on the device to avoid
damaging the coating and degrading the performance of the device.
The dome cover is an optical component. When it is contaminated with dust, grease, or
fingerprints, use degreasing cotton moistened with a little ether or a clean soft cloth dipped in
water to gently wipe it clean. An air gun is useful for blowing dust away.
It is normal for a camera made of stainless steel to develop rust on its surface after being used in
a strong corrosive environment (such as the seaside, and chemical plants). Use an abrasive soft
cloth moistened with a little acid solution (vinegar is recommended) to gently wipe it away.
Afterwards, wipe it dry.

Connecting Alarm Input/output
Alarm input/output is available on select models.
Connect alarm input device to the alarm input end of the I/O port.
Device collects different states of alarm input port when the input signal is idling and being
grounded.
Device collects logic "1" when input signal is connecting to +3 V to +5 V or idling.
Device collects logic "0" when input signal is grounded.
Alarm input
Connect alarm output device to the alarm output end of the I/O port. The alarm output is
open-drain output, which works in the following modes.
Mode A: Level application. Alarm outputs high and low level, and the alarm outlet is OD,
which requires external pull-up resistance (10 K Ohm typical) to work. The maximum
external pull-up level is 12 V, maximum port current is 300 mA and the default output
signal is high level (external pull-up voltage). The default output signal switches to low
level when there is alarm output (As long as the operating current below 300 mA, the
output low level voltage is lower than 0.8 V).
Mode B: Switch application. Alarm output is used to drive external circuit, the maximum
voltage is 12 V and the maximum current is 300 mA. If the voltage is higher than 12 V,
please use an additional electric relay.
Mode A

Mode B
Log in webpage, and configure alarm input and alarm output in alarm setting.
The alarm input in the webpage is corresponding to the alarm input end of the I/O port.
There will be high level and low level alarm signal generated by the alarm input device
when alarm occurs, set the input mode to "NO" (default) if the alarm input signal is logic
"0" and to "NC" if the alarm input signal is logic "1".
The alarm output in the webpage is corresponding to the alarm output end of the device,
which is also alarm output end of the I/O port.
