Important Safeguards and Warnings

This chapter describes the contents covering proper handling of the Camera, hazard prevention, and prevention of property damage. Read these contents carefully before using the Camera, comply with them when using, and keep it well for future reference.

Power Requirements

• All installation and operation should conform to your local electrical safety code.
• Check whether the power supply is correct before operating the Camera.
• 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. Note that the power supply requirement is subject to the Camera label.
• Install easy-to-use devices for power off before installing wiring, which is for emergent power off when necessary.
• Prevent the line cord from being trampled or pressed, especially the plug, power socket and the junction from the Camera.

• Risk of explosion if the battery is replaced by an incorrect type.
• Replacement of a battery with an incorrect type that can defeat a safeguard (for example, in the case of some lithium battery types).
• Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery can result in an explosion.

• High or low extreme temperatures that a battery can be subjected to during use, storage or transportation; and low air pressure at high altitude.

• Leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of flammable liquid or gas.
  A battery subjected to extremely low air pressure that may result in an explosion or the leakage of flammable liquid or gas.

Application Environment Requirements

• Use the Camera within the allowed humidity and altitude.
• Do not use the Camera in the strong vibration environment such as in boats and vehicles.

If you still want to use thermal cameras in the two conditions mentioned above, please contact our sales staff to buy cameras of special model or cameras that are customized. If you use cameras in improper environments, we shall not take the costs of camera damage.

• There is a default temperature monitoring range of targets for the Camera. Use the Camera within the range.
• Use the Camera within the required working temperature and humidity.
• Do not place the Camera in the humid, dusty, extremely hot and cold site with strong electromagnetic radiation or unstable illumination.
• Do not block the ventilation of the Camera to avoid heat accumulation.

• Do not install the Camera near the heat source such as radiator, heater, and stove to avoid fire.

• Do not aim the lenses at intense radiation source (such as sun, laser, and molten steel) to avoid damage to thermal detector and visible lens.

• Prevent liquid from flowing into the Camera to avoid damage to the internal components. In case the liquid entering the Camera, immediately stop using the Camera, cut off the power, and disconnect all the cables. Then contact the local customer service center.
• Do not stuff foreign materials into the Camera to prevent short circuit which could cause Camera damage or injury.
• Use the factory default package or material with equal quality to pack the Camera when transporting the Camera.
• Do not press, vibrate or soak the Camera during transportation, storage and installation.

Operation and Maintenance Requirements

• Do not touch the heat dissipation component of the Camera in case you might get burnt.
• Do not dismantle the Camera; there is no part which can be repaired by users themselves. It may cause water leakage or bad image for the Camera if it is dismantled unprofessionally.
• It is recommended to use the Camera together with a lightning arrester, which is to improve the effect of lightning protection. It needs to conform to the lightning protection regulation for outdoor application.
• Do not touch the photosensitive Camera with your hands. Use an air blower to clean the dust on the lens. For further cleaning, pour a little alcohol into a piece of dry cloth with which you can softly wipe the dirt away.
• Clean Camera body with a piece of soft dry cloth. For any dirt hard to remove, pick up a piece of clean and soft cloth, dip it with a little neutral detergent and gently wipe the dust away—after that, wipe all the liquids on the Camera away with another dry cloth. Never use any volatile solvent such as alcohol, benzene and thinner, or any cleaner that is strong and abrasive. Otherwise, the Camera's surface coating will be hurt and its working performance will be encumbered.

WARNING

• Use the accessories regulated by the manufacturer. The Camera should be installed and maintained by professionals.
• Contact the local dealer or the nearest service center if the Camera fails to work normally. Do not dismantle or modify the Camera.

Step 5 Configure temperature monitoring parameters.

• Press /to select parameters.
• Press to confirm.
• On the parameter configuration interface, press to increase or decrease the parameter value.

Table 4-1 Temperature parameter description

Parameter	Description
Pseudo Color	Press to switch to pseudo color mode.
Emissivity	Set emissivity for different monitoring targets as needed. The default value is 0.98.
Distance	The distance between the monitoring target and the Camera.Ensure that the actual distance is consistent with this value, otherwise it will affect the temperature monitoring accuracy.
Unit	Temperature unit. Supports° C,° F and K.

Step 6 Press to save the configuration and quit.

4.2 Temperature Monitoring Settings

- On the parameter configuration interface, press to increase or decrease the parameter value.

Table 4-2 Parameter description of temperature monitoring

Parameter	Description
Alarm Settings	Alarm Threshold: Set the alarm threshold value. An alarm will be triggered when the temperature of the monitoring target exceeds the alarm threshold. On the live interface, the temperature that exceeds the alarm threshold flashes and is displayed in red.Snapshot: Set whether to enable snapshot when an alarm is triggered.Buzzer: Set whether to beep when an alarm is triggered.Enabling snapshot or buzzer will reduce the battery life of the Camera.
EnvTemp Mode	Set ambient temperature mode.Self-adaptive Mode: The Camera calculates the ambient temperature automatically. SelectSelf-adaptive Mode, and then press to set the current ambient temperature as the reference temperature.Manual Mode: Set the current ambient temperature manually.
Temp Correction	The difference of the temperature monitoring environment might cause the temperature deviation between the monitored temperature and the actual temperature. You can select multiple monitored samples for testing, and then correct the temperature deviation by this parameter according to the comparison between the monitored temperature and the actual temperature. For example, if the monitored temperature is 0.5°C lower than the actual temperature, the correction value is set to 0.5°C; if the monitored temperature is 0.5°C higher than the actual temperature, the correction value is set to -0.5°C.

Step 6 Press to save the configuration and quit.
