Important Safeguards and Warnings

Electrical Safety

  • All installation and operation shall conform to your local electrical safety codes.
  • The power supply must conform to the requirements of ES1 in IEC 62368-1 standard and be no higher than PS2. Note that the power supply requirements are subject to the device label.
  • Make sure that the power supply is correct before operating the device.
  • A readily accessible disconnecting device shall be incorporated in the building installation wiring.
  • Prevent the power cable from being trampled or pressed, especially the plug, power socket and the junction extruded from the device.


  • Do not aim the device at strong light to focus, such as lamp light and sun light; otherwise it might cause over brightness or light marks, which are not device malfunctions, and affect the longevity of Complementary Metal-Oxide Semiconductor (CMOS).
  • Do not place the device in a damp, dusty extremely hot or cold environment, or the locations with strong electromagnetic radiation or unstable lighting.
  • Keep the device away from any liquid to avoid damage to the internal components.
  • Keep the indoor device away from rain or damp to avoid fire or lightning.
  •  Keep sound ventilation to avoid heat accumulation.
  • Transport, use and store the device within the range of allowed humidity and temperature.
  • Heavy stress, violent vibration or water splash are not allowed during transportation, storage and installation.
  • Pack the device with standard factory packaging or the equivalent material when transporting the device.
  • Install the device in the location where only the professional staff with relevant knowledge of safety guards and warnings can access. The accidental injury might happen to the non-professionals who enter the installation area when the device is operating normally.

Operation and Daily Maintenance

  • Do not touch the heat dissipation component of the device to avoid scald.
  • Carefully follow the instructions in the manual when disassembling operation about the device; otherwise, it might cause water leakage or poor image quality due to unprofessional operations. Make sure that the gasket ring is flat and properly installed in the groove before installing the cover. Contact after-sales service for desiccant replacement if there is condensed fog on the lens after unpacking or when the desiccant turns green (Not all models are included with the desiccant).
  • We recommend using the device together with lightning arrester to improve lightning protection effect.
  • We recommend grounding the device to enhance reliability.
  • Do not touch the image sensor (CMOS) directly. Dust and dirt could be removed with air blower, or you can wipe the lens gently with soft cloth that is moistened with alcohol.
  • You can clean the device body with soft dry cloth, and for stubborn stains, use the cloth with mild detergent. To avoid possible damage on device body coating which could cause performance decrease, do not use volatile solvent such as alcohol, benzene, diluent to clean the device body, nor can strong, abrasive detergent be used.
  • Dome cover is an optical component. Do not touch or wipe the cover with your hands directly during installation or operation. For removing dust, grease or fingerprints, wipe gently with moistened oil-free cotton with diethyl or moistened soft cloth. You can also remove dust with an air blower.
  • Strengthen the protection of network, device data and personal information by adopting measures which include but not limited to using strong password, changing password regularly, upgrading firmware to the latest version, and isolating computer network. For some devices with old firmware versions, the ONVIF password will not be changed automatically along with changing the system password, and you need to upgrade the firmware or manually change the ONVIF password.
  • Use standard components or accessories provided by manufacturer and make sure that the device is installed and maintained by professional engineers.
  • Do not expose the surface of the image sensor to laser beam radiation in an environment where a laser beam device is used.
  • Do not provide two or more power supply sources for the device unless otherwise specified. A failure to follow this instruction might cause damage to the device.


Waterproof all the cable joints with insulating tape and waterproof tape to avoid short circuit and  water damage. For the detailed operation, see the FAQ manual.

Connecting Alarm Input/Output

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

  • Step 1 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 connected to +3 V to +5 V or idling.
    • Device collects logic “0” when input signal is grounded.
  • Step 2 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 is 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.dahua IPC-HFW3241DF-AS-4G Bullet Network Camera-fig5
  • Step 3 Log in to web interface, and configure alarm input and alarm output in alarm setting.
    • The alarm input on the web page 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 on the web interface is corresponding to the alarm output end of the device, which is also alarm output end of the I/O port.

Network Configuration

Device initialization and IP setting can be finished with the ConfigTool or on web interface. For more information, see the web operation manual.

  • Device initialization is available on select models, and it is required at first-time use and after device is being reset.
  • Device initialization is available only when the IP addresses of the device ( by default) and the PC stays in the same network segment.
  • Plan usable network segment properly to connect the device to the network.
  • The following figures are for reference only.

Initializing Device

  • Step 1 Double-click ConfigTool.exe to open the tool.

  • Step 2 Click .

  • Step 4 Select the searching way.

    • Current Segment Search (default)
      Select the Current Segment Search check box. Enter the user name in the Username box and the password in the Password box. The system will search devices accordingly.

    • Other Segment Search
      Select the Other Segment Search checkbox. Enter IP address in the Start IP box and End IP box respectively. Enter user name and password. The system will search the devices accordingly.

    • If you select the Current Segment Search check box and the Other Segment Search check box together, the system searches for devices under both conditions.

    • Enter username and the password when you want to change IP, configure the system, update the device, restart the device, and more.

  • Step 5 Click OK.

  • Step 6 Select one or several devices in uninitialized status, and then click Initialize.

  • Step 7 Select the devices to be initialized, and then click Initialize.

    • If you do not provide the reserve information for password reset, you can reset the password only through XML file.
    • When initializing multiple devices, ConfigTool initializes all devices based on the password reset mode of the first selected device.dahua IPC-HFW3241DF-AS-4G Bullet Network Camera-fig7
