The core of security and access control systems lies in 24/7 reliability and rapid response. With the development of smart cities and IoT, security equipment is shifting from passive monitoring to active alerts and intelligent analysis. This presents multiple challenges for drive components: 1) All-Weather Reliability: Equipment (especially outdoor PTZ cameras and barriers) must operate 24/7 in wide temperature ranges (-40°C to +85°C), high humidity, and dust. 2) Long Life & Zero Maintenance: Devices are often installed in high or hard-to-reach locations, requiring components (like motors) to have ultra-long lifespans of tens of thousands of hours. 3) Quiet & Smooth Operation: In high-end indoor access control (e.g., office turnstiles) and surveillance, any operating noise degrades product quality. 4) Fast Response & Precision: PTZ cameras need millisecond response to capture dynamic targets and recall presets with zero cumulative error.
AKT Product Solution
AKT provides robust and responsive drive units for security systems, prioritizing Hybrid Stepper Motors and Brushless DC Motors (BLDC).
- High-Precision Smooth Rotation (PTZ) Solution:
For Pan-Tilt-Zoom (PTZ) camera applications, our high-precision hybrid stepper motors (e.g., NEMA 14, 17, 23) are the mainstream choice. The digital control nature of steppers allows for precise angular positioning. We especially recommend our 0.9° high-resolution stepper motors. Their finer step angle, combined with the micro-stepping and vibration suppression algorithms of our high-performance stepper drivers, enables extremely smooth low-speed cruising (no “cogging”) and pinpoint-accurate high-speed preset recalls, ensuring stable video capture. - High-Durability & Quiet (Access Control) Solution:
For automatic doors, subway turnstiles, and high-end barrier gates, our BLDC motors paired with planetary gearboxes are the ideal combination for high performance. BLDC motors offer smooth start/stop, extremely low noise, and precise speed and position control (for anti-pinch functions). Their brushless design ensures a lifespan of tens of millions of cycles, far exceeding traditional brushed motors, making them perfect for high-throughput applications like subway gates. - High-Reliability Transmission Solution:
Our planetary gearboxes (available in 42mm, 60mm, etc.) provide compact, high-efficiency torque multiplication for these motors. Their high torsional stiffness and low backlash (down to ≤10 arc-minutes) ensure the rigidity of PTZ positioning and the smoothness of gate operation.
Engineering & Customization Capabilities:
We offer deep customization for the security industry: including the use of wide-temperature grease and special materials for extreme climates, high-protection-rated (IP65) sealed designs, custom motor windings to match 24VDC security standards, and integration of high-resolution encoders (for PTZ closed-loop feedback) or electromagnetic brakes (for power-off locking of barrier arms).
Typical Application Equipment Examples
- High-Speed Domes / Heavy-Duty PTZ:
The core of a PTZ is its Pan and Tilt movement. Our 0.9° high-resolution stepper motors, with their superior angular resolution and high holding torque at standstill, ensure the camera remains stable even in high winds. Paired with silent drivers, they produce no audible noise during quiet nighttime patrols, enabling covert surveillance. - Subway / Rail Station Turnstiles:
Turnstiles demand absolute reliability under extremely high traffic (tens of thousands of cycles per day). Our BLDC motor + planetary gearbox drive module, combined with a driver using FOC algorithms, provides fast, smooth, and quiet gate motion. It also allows for precise torque control to implement safety features like obstacle-detection-reverse. - Parking Barrier Gates:
Barrier gates require motors to lift long arms quickly (e.g., 1-second lift) and smoothly, locking reliably at any position. Our BLDC servo motor combined with a planetary gearbox and an electromagnetic brake provides powerful torque and fast acceleration control, ensuring the arm moves without jitter and locks instantly upon power loss.
