Backup Battery
LiPo
Capacity: 3250 mAh
Energy: 23.4 Wh
Backup Battery Operating Time (at room temperature)
Battery preservation mode is enabled by default when powered via PoE. In the event of a sudden power loss, estimated runtime is:
Gateway Mode: approx. 45 min
Relay Mode: approx. 30 min
Battery preservation mode: when powered via PoE, the system keeps battery voltage between 7.0 V and 7.4 V. If the battery voltage at insertion exceeds 7.5 V, the system will discharge it to the safe threshold before entering preservation mode; the battery will not charge to full capacity.
Battery discharge performance may decrease in low temperatures, reducing actual operating time.
Backup Battery Charging
Supports 9V or 12V PD charging. DJI 65W Portable Charger is recommended before deployment. When fully charged, estimated runtime in Gateway Mode is approx. 2 hours.
Charge time (65W PD): approx. 2.5 hours
Charging with a 5V charger is only supported when the device is powered off.
Charging is only supported when the battery cell temperature is between 0° and 55° C (32° and 131° F).

Physical Characteristics
Ethernet Port Surge Protection
WAN/LAN Ports: Ethernet interface supports up to 10kA (total discharge current) surge protection, meeting EN/IEC 61643-21 Category C.
RJ45 surge protection capacity is 1.5kA (8/20μs waveform), meeting the Category C protection level of EN/IEC 61643-21. Surge protection capability depends on the capacity and reliability of grounding. To minimize the risk of surges, please make sure that grounding is done properly during installation.
Operating Temperature
IEEE 802.3bt Type 4 (PoE++): -40° to 55° C (-40° to 131° F)

External Device Support
After correctly connecting an ONVIF IP camera to DJI O4 Ground Station, the video feed is not visible in DJI FlightHub 2. What could be causing this?
1. Check IP configuration:
If the camera and the WAN port of DJI O4 Ground Station are connected to the same switch, enable DHCP on the camera.
2. Confirm that the camera supports the ONVIF protocol and that ONVIF has been enabled in the camera's configuration tool.
3. If ONVIF is enabled but the camera still cannot be discovered, use a third-party tool such as ONVIF Device Manager on a PC to verify whether the camera is discoverable on the network.
4. If the camera icon appears in DJI FlightHub 2 but the video stream fails to load, enter the camera's administrator credentials (username and password) to complete authentication.

What video formats does DJI O4 Ground Station support for third-party IP cameras? Is PTZ control supported? Are camera alerts supported?
1. Only H.264 video streams are supported, supporting up to 4 simultaneous live streams.
2. If the camera supports PTZ control (Pan/Tilt/Zoom), PTZ control is available from the live stream page in DJI FlightHub 2 once the camera is connected.
3. If the camera supports motion detection or occlusion alerts, enable alert notifications in the camera configuration interface. Alerts will be pushed through DJI FlightHub 2.
The above features depend on camera-side support. If the camera does not support or is not compatible with these functions, the corresponding features in DJI FlightHub 2 may not be available.

How should IP cameras be connected to DJI O4 Ground Station? How are cameras powered?
1. ONVIF cameras and the WAN port of DJI O4 Ground Station should each be connected to the same network switch.
2. DJI O4 Ground Station does not provide power to downstream devices. IP cameras must be powered via an external PoE switch or a dedicated DC power adapter.

What types of IP cameras are compatible with DJI O4 Ground Station?
1. ONVIF cameras: H.264 encoding is required. With DHCP enabled, the camera can connect via the WAN port.
2. GB/T 28181 cameras: H.264 encoding is required. The camera must be on the same subnet as the WAN port of DJI O4 Ground Station. Automatic IP assignment on the ground station must be disabled and a static IP must be configured.
3. For a list of tested camera models and deployment instructions, visit the Downloads page on the DJI website.

Does DJI O4 Ground Station support connecting IP cameras in Relay Mode?
No. Relay Mode does not support internet connectivity. Switch to Gateway Mode to connect IP cameras.
Where can I find and purchase Remote ID and ADS-B receivers compatible with DJI O4 Ground Station?

Gateway Mode
What are the switch requirements for DJI O4 Ground Station?
A Gigabit PoE switch is recommended to simultaneously provide network access and PoE power to DJI O4 Ground Station. Ensure the PoE power class meets the requirements for the operating temperature range. Refer to the Specs page for details.
What are the network bandwidth requirements for DJI O4 Ground Station?
A minimum bandwidth of 100 Mbps is recommended. If IP cameras are also being deployed, a dedicated network is recommended to reduce latency.
Is there a distance limit when deploying DJI O4 Ground Station via Ethernet?
1. There is no distance restriction between DJI O4 Ground Station and DJI Dock 3.
2. The maximum deployment distance between DJI O4 Ground Station and the network switch is 100 m.
2. The maximum deployment distance between DJI O4 Ground Station and the network switch is 100 m.
Why does takeoff take longer after DJI O4 Ground Station is connected to DJI Dock 3?
Before the aircraft takes off, selecting DJI O4 Ground Station as the communication relay requires the system to pre-load linking data. This adds approximately 10 seconds to the pre-flight preparation process.
DJI O4 Ground Station cannot connect to the cloud platform. What could be causing this?
1. Verify that the PoE power supply type meets the requirements. Non-standard PoE or Type 1 supplies cannot power DJI O4 Ground Station. Operation in environments from -40° to 55° C (-40° to 131° F) requires a Type 4 (PoE++) supply with sufficient per-port power output.
2. Confirm that the ground station is in Gateway Mode (Mode Indicator light: purple). Relay Mode (Mode Indicator light: blue) does not support direct internet connectivity. Press the power button three times consecutively to switch to Gateway Mode before deploying.
3. Verify network connectivity. A network test can be performed from within the DJI Enterprise app during deployment.
4. Verify that network bandwidth is no lower than 100 Mbps.
5. Verify that both ends of the Ethernet cable are terminated in T568B wiring order. A cable tester can be used to help confirm.

Relay Mode
What is the sub2G band on DJI O4 Ground Station used for?
Sub2G refers to radio frequencies below 2 GHz*. On compatible aircraft, enabling sub2G extends transmission range and improves interference resistance between the aircraft and the remote controller.
* Sub2G band support is only available when using DJI O4 Ground Station with Matrice 400. This feature is not available in certain countries or regions. Check local laws and regulations for more information.

What is the default Remote Access password for Relay Mode? What should I do if I forget the password?
1. The default password is 123456. You are required to change this password upon initial access.
2. The remote controller and DJI FlightHub 2 store passwords for previously connected ground stations. After a successful connection, the password can be viewed in the app. Keep a record of any updated password.
3. If no previously connected remote controller is available, press and hold the power button on DJI O4 Ground Station for 8 seconds to reset the password to the default value of 123456.
