The body is constructed of high-strength die-cast aluminum alloy material, with a net weight of 23kg, a 40% increase in structural rigidity, a top or side load of up to 50kg, and easy integration of heavy telephoto lenses or thermal imagers.
The built-in high-precision steel worm gear transmission system achieves a repeated positioning accuracy of 0.1 degrees. Compared with the traditional belt transmission, the gap wear is reduced by 85%, and the mechanical self-locking is realized when the power is off to prevent the lens from hanging down.
Strict IP66 protection grade sealing design, with the optional internal temperature control system, supports continuous work under the extreme temperature difference of -35 ℃ to 65 ℃, and effectively resists rain, snow, sand and salt spray corrosion.
The integrated conductive slip ring supports 360-degree unlimited continuous rotation, solves the problem of traditional cable winding, and can simultaneously transmit power supply, video signal and RS485 control signal, reducing signal transmission loss to 0.01.
The built-in decoder board supports mainstream industry standard protocols such as Pelco-D/P, and the baud rate is adjustable from 2400bps to 19200bps. It is compatible with 98% of security terminals and industrial control systems on the market and seamlessly interfaces with existing platforms.
Low-speed smooth operation, the minimum speed of up to 0.01 degrees/second, combined with high torque motor design, in the 12 strong wind can still keep the picture stable without jitter, not only suitable for static monitoring, more suitable for dynamic tracking applications.

For multi-sensor fusion scenarios, we solved the problem of motor overload and burn-out caused by the inability of ordinary gimbal to mount telephoto cameras and laser rangefinders at the same time..
in view of the high wind speed environment of border and coastal defense, we have solved the problem that the traditional pan-tilt gear slips under strong wind and cannot focus the monitoring picture violently..
in view of the unstable power supply in the field, we have solved the maintenance problem that the position of the pan/tilt is lost after an unexpected power failure and needs to be manually recalibrated..
It is suitable for border and coastline projects requiring long-distance monitoring. It can carry heavy ultra-long focus lens and laser night vision equipment, and can operate stably for a long time in salt spray and humid environment to meet the needs of national defense-level monitoring.
For forest high-point observation monitoring, the pan-tilt supports infrared thermal imaging and visible light dual-spectrum load, and realizes all-weather fire warning for several kilometers around the forest area through 360-degree automatic cruise function and fire point detection algorithm.
It is suitable for highway and urban road monitoring. The high-precision positioning capability ensures that the license plate can be accurately locked when the telephoto is captured. The wind-resistant design ensures that the picture is still clear when the vehicle passes at high speed to generate airflow or bridge vibration.
For factory automation inspection lines or special robots, it provides programmable precision motion control. As the motion joint of mechanical arm or vision inspection system, it carries various sensors for repetitive high-precision scanning.
When installing the camera or protective cover, be sure to adjust the front and rear position to ensure that the center of gravity of the load is located on the center axis of the gimbal. This can reduce the motor load, extend the life of the equipment and prevent running jitter..
Use M8 high-strength screws to firmly install the pan-tilt base on the bracket, and apply industrial-grade silicone sealant to the cable lead-in hole and the joint of the base to prevent rainwater from entering the fuselage along the cable..
When connecting the control line, please strictly distinguish the positive and negative of RS485. It is recommended to use shielded twisted pair. When the transmission distance exceeds 800 meters, it is recommended to increase the 120 ohm terminal resistance to eliminate signal reflection interference..
Before powering on, set the communication address and baud rate of the pan-tilt through the dip switch at the bottom to ensure that they are completely consistent with the settings of the control terminal or hard disk video recorder, otherwise the pan-tilt cannot be controlled to rotate..
The standard version has a maximum load of 90kg. For special heavy load requirements, we provide enhanced customized services.
Yes, the gimbal has a position memory chip integrated inside it. When the system is accidentally powered off, the gimbal will record the current angle coordinates, and can automatically restore to the position or preset position before power off without self-test after power on again.
Standard models have included basic low temperature resistant design. If it is used in an extremely cold environment below -35 ℃, it is recommended to select an automatic temperature control heating component. The system will automatically start heating at low temperatures to prevent the grease from solidifying.
Supports standard Pelco-D and Pelco-P protocols, which are common standards in the security industry. As long as your NVR or control keyboard supports RS485 control and the above protocol, it can be perfectly compatible control.
You can. The gimbal supports side-load or top-load installation, and an auxiliary power supply interface is reserved. You can install a camera on one side and an infrared fill light or radar device on the other side by installing a double-sided bracket.
You can. The gimbal supports stepless speed change, and the rotation speed is proportional to the amplitude of the control rocker (keyboard support is required). The specific cruising speed can also be set by command, ranging from 0.01 degrees/second to 15 degrees/second.
