Important Safeguards and Warnings

Operation Requirement

Do not place or install the device in a place exposed to sunlight or near the heat source.

Keep the device away from dampness, dust or soot.

Keep the device installed horizontally on the stable place to prevent it from falling.

Do not drop or splash liquid onto the device, and make sure there is no object filled with

liquid on the Camera to prevent liquid from flowing into the device.

Install the device in a well-ventilated place, and do not block the ventilation of the Camera.

Operate the device within the rated range of power input and output.

Do not dissemble the device.

Transport, use and store the device under the allowed humidity and temperature conditions.

Electrical Safety

Improper battery use might result in fire, explosion, or inflammation.

When replacing battery, make sure the same model is used.

Use the recommended power cables in the region and conform to the rated power

specification.

Use the power adapter provided with the device; otherwise, it might result in people injury

and device damage.

The power source shall conform to the requirement of the Safety Extra Low Voltage (SELV)

standard, and supply power with rated voltage which conforms to Limited power Source

requirement according to IEC60950-1. Please note that the power supply requirement is

subject to the device label.

Connect the device (I-type structure) to the power socket with protective earthing.

The appliance coupler is a disconnection device. When using the coupler, keep the angle

for easy operation.

Maintenance Requirement

Do not try to disassemble the device yourself.

Do not touch charge-coupled device (CCD) or complementary metal oxide semiconductor

(CMOS) directly. Use a blower to remove dust or dirt from the sensor surface.

Use a soft, dry and clean cloth soaked with a small amount of neutral detergent to clean the

Camera.

Declarations

Please read the Guide carefully before installation. Keep the Guide properly for future

reference.

Pay attention to factors such as environmental requirements, application scenarios to avoid

error of system caused by external factors.

Illustrations and descriptions of devices in the Guide are for reference only, and the actual

devices shall prevail.

Devices and software subject to change without further notice.

For latest programs and additional files, please contact our customer service.

Construction Safety Instructions

Construction workers must wear protective equipment such as reflective vest to ensure

safety during construction.

Construction sites must be blocked off and placed with signs. Specific requirements are as

follows:

Work on city road: Place in sequence work zone warning sign, work zone speed limit sign,

and traffic guidance sign 150 meters away of coming vehicles from the work zone. In

addition, put work zone safety barriers at reasonable intervals to form a safe work zone and

protect workers’ safety.

Work on expressway: Put work zone warning sign at safe area (such as near hard

shoulder or crash barrier) and 1.5 km away of coming vehicles from the work zone. In

addition, place in sequence work zone speed limit sign, traffic guidance sign, and work zone

distance sign around 150 meters to the work zone. Put work zone safety barriers at

reasonable intervals to form a safe work zone, and place traffic guidance sign at corners of

the work zone. Put sign of canceling work zone speed limit at a safe place 150 meters away

of leaving vehicles from the work zone.

Lifting work or aerial work: The work zone must be placed with clear danger sign and

danger warning light at night. Responsible person should be designated to guide people to

detour. Do not enter or stay in work area.

Aerial work platform: Make sure that its parking position is ideal for aerial work. Check

whether the support legs of aerial work platform are put in place to support the telescopic

boom, and whether heavy-current circuit is connected within the work zone. Make sure the

boom will not touch any object when it is extended.

Workers should fasten safety belt and wear helmet, and properly place equipment, tools

and personal belongings to prevent injuries from falling objects.

Heavy current engineering: During wiring, joint with the heavy current part exposed should

be wrapped with insulated and waterproof tape, which will be put into waterproof insulated

box. When the device is connected to heavy current, make sure the circuit works, and the

insulation cover of cable is inserted into terminal to prevent the insulation cover separating

from the copper wire, resulting in the copper wire exposed. For old wire construction, make

sure no power is connected, and then start construction.

Grounding: Make sure all electric devices are properly grounded during construction.
