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.

●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

Quick Start Guide

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.

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.

Quick Start Guide

●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.

and ALARM_OUT_GND port with the same number can be used

together.

ALARM_OUT_GND

1.2 Connecting Alarm Input/Output

Background Information

The camera can connect to external alarm input/output devices through digital input/output.

Alarm input/output is available on select models.

Procedure

Step 1 Connect the alarm input device to the alarm input end of the I/O port.

Device collects different status of alarm input port while the input signal is idling and

being grounded.

●Device collects logic "1" when the input signal is connected to +3 V to +5 V or idling.

●Device collects logic "0" when the input signal is grounded.

Quick Start Guide

Figure 1-2 Alarm input

Step 2 Connect the alarm output device to the alarm output end of the I/O port. The alarm output

is a relay switch output, which can only connect to OUT_GND alarm devices.

ALARM_OUT(ALARM_COM) and ALARM_OUT_GND(ALARM_NO) constitute a switch that

provides the alarm output.

The switch is open normally and closed when there is an alarm output.

ALARM_COM might represent ALARM_C or C; ALARM_NO might represent N. The

following figure is for reference only, please refer to the actual device for more

information.

Figure 1-3 Alarm output

Step 3 Log in to the webpage, and then configure the alarm input and alarm output in alarm

settings.

●The alarm input on the webpage corresponds with the alarm input end of the I/O port.

There will be high level and low level alarm signals generated by the alarm input device

when an 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 on the webpage corresponds with the alarm output end of the

device, which is also the alarm output end of the I/O port.
