Worm Gear Drive
Using high-precision worm gear transmission structure, with precision stepping motor, the backlash is controlled within 0.1 degrees. Compared with traditional gear transmission, the image jitter rate is reduced by 85%, ensuring that the telephoto lens remains stable under 30 times magnification.
The unit body is made of high-strength die-cast aluminum alloy and has passed the 12-hour neutral salt spray test with special powder coating. The built-in automatic temperature control system supports continuous operation in extreme environments ranging from minus 35 degrees to 65 degrees. The protection level reaches IP66 standard, effectively resisting rain, snow and sand.
Designed for small PTZ system integration, the Pan Tilt Unit offers a top load capacity of up to 10kg. The special transmission ratio design allows the vertical rotation torque to reach 12 Nm, which easily carries the combined load of the telephoto lens, laser illuminator and thermal imager.
The internal integrated multi-channel conductive slip ring supports power, video, network and RS485 signal transmission. The problem of cable winding and wear caused by external flying wires is completely solved, and the average trouble-free operation time of the system is extended to more than 8000 hours.
Full support for Pelco-D, Pelco-P and industry standard Onvif protocol, baud rate 2400bps to 19200bps adaptive. System integrators can connect devices to existing security management platforms without writing additional driver code, increasing deployment efficiency by 60%.
With mechanical self-locking function, the position of the pan/tilt will not shift even if it bears the maximum wind load in the power-off state. After re-powering, through the absolute encoder technology, it can be accurately restored to the preset position angle before power failure within 3 seconds without self-checking.

In view of the difficult problem that cables are difficult to arrange when system integrators mount radar and searchlights, we have solved the hidden dangers of easy hanging up and aging of external wiring through built-in multi-gigabit ports and power slip rings, and realized plug and play..
In view of the problem that small vibrations will be amplified in remote monitoring scenarios, we use zero-gap worm transmission to completely solve the rebound jitter generated by ordinary gear pan-tilt when it stops, ensuring that targets several kilometers away can be captured clearly..
In view of the high corrosion environment of coastal and chemical parks, we have solved the problem that the conventional paint shell is easy to peel off and rust. The three-layer fluorocarbon baking process and stainless steel fasteners are used to extend the corrosion resistance life of the shell to more than 8 years..
Applicable to the need for long-distance detection of border monitoring projects. The Pan Tilt Unit’s high load capacity can easily mount heavy telephoto fog lens and thermal imaging equipment, and with its anti-wind resistance design, it is perfectly suitable for unattended base stations in the wild with strong wind such as mountains and islands.
It is suitable for the traffic incident detection system of highway and urban road. The product’s fast response and precise positioning capabilities can cooperate with radar linkage to capture speeding or illegal vehicles. The wear resistance under high-frequency reciprocating motion meets the needs of all-weather road inspection.

Applicable to large ports, oil fields and chemical industry park commanding height panoramic monitoring. Through the multi-sensor fusion technology integrated with the PTZ, the manager can carry the gas detector and the visible light camera at the same time to realize the remote visual investigation and automatic early warning of the hidden danger of production safety.
It is suitable for scientific research projects that need customized vehicles, such as vehicle mobile patrol or shipborne photoelectric tracking system. Its open protocol interface and wide voltage input design make it easy for engineers to integrate it into the control system of mobile robots or special vehicles as a high-precision pointing mechanism.
The Pan Tilt Unit bottom flange is fixed to the bracket with 4 M10 stainless steel bolts. Be sure to use a spirit level to detect the flatness of the installation surface, and the inclination should be less than 1 degree to prevent uneven bearing force of the motor shaft caused by long-term operation..
When installing the camera or radar load, slide the mounting plate forward and backward to find the center of gravity balance point. Ensure that the center of gravity of the load coincides with the rotation axis of the gimbal, and the error is controlled within 5mm. This is a key step to ensure the life and positioning accuracy of the motor..
Connect the power line, control line and network line according to the wiring diagram. After the connection is completed, the attached waterproof glue must be used to wrap and seal the interface to prevent condensation water from penetrating into the fuselage along the cable and causing a short circuit on the main board..
Open the side access cover and set the baud rate and communication address according to the manual comparison table. After the setting is completed, the equipment needs to be powered off and restarted, and the pan/tilt will automatically perform self-check rotation. After returning to its position, it can be operated through the control keyboard or software..
Although the nominal center load is 10kg, if the center of gravity of the load deviates from the center of rotation by more than 50mm, it is recommended to reduce the load weight to less than 8kg. Excessive partial load will cause the motor to overheat protection, and long-term use will accelerate the wear of the worm gear.
Support. The device is internally integrated with a high-precision potentiometer or encoder, which can query the current horizontal and vertical angle values in real time through RS485 instructions, and the feedback accuracy can reach 0.1 degrees, which is convenient for integrators to develop radar linkage tracking function.
You can. The product has a built-in intelligent heating module. When it is detected that the internal temperature of the machine is lower than minus 10 degrees, the heater will start preheating first, and the motor will not be powered on until the temperature of the standby body returns to the working range, so as to prevent the grease from solidifying and damaging the gear due to low temperature.
The system board supports the storage of up to 128 preset bits and the ability to set up to 6 cruise scan paths. Each path contains up to 16 preset points, and the dwell time and speed of each point can be independently programmed.
Support customization. The standard version is equipped with network and power channels. If your project requires SDI video signal, optical fiber signal or more current channels, we provide customized slip ring service, usually with a customized cycle of 15 working days.
The power input and communication interface of the equipment are designed with TVS transient suppression diode and gas discharge tube, with 6000V lightning protection and surge protection capability. However, when installing in outdoor high thunderstorm areas, it is still recommended to install a professional external lightning protection device at the front end.
