Detailed specifications and benefits
The DS‑TDSB0G‑FK/120m uses an FMCW (frequency modulated continuous wave) phased‑array radar operating within the 24.05–24.25 GHz band and a 115 MHz sweep bandwidth. This enables precise distance and velocity measurement, with a distance resolution of approximately 1.3 m and distance accuracy of ±1.2 m. The unit can scan up to 12 times per second, providing fast detection updates across a horizontal coverage of 120° and vertical coverage of 30°.
Practically, the radar is tuned for human detection to 120 m and vehicle detection to 200 m. It supports tracking of up to 32 targets and allows definition of up to 16 zones and 4 trigger lines, giving security teams fine control over where and how alerts are generated. Angle accuracy is around ±1° with an angle resolution of 12°, while speed measurements span −19 to 19 m/s with good resolution and accuracy.
One of the notable benefits of this Hikvision radar is its layered approach to alarm verification. The radar performs onboard analysis to classify detections and can automatically trigger a linked PTZ camera to capture and store short video clips to re‑check and confirm events. Scene presets and configurable sensitivity levels allow installers to tune the system to local conditions and minimise nuisance alarms from animals, vegetation or benign motion.
On the network side, the unit provides a 1 GbE RJ45 interface and supports common protocols such as TCP/IP, RTSP/RTP and secure HTTP/HTTPS with TLS 1.2. Integration is straightforward via Hikvision SDK and ISAPI, and the radar is compatible with central management platforms such as iVMS‑4200 and Hik‑Central Pro. For local recording and immediate video re‑check, the radar includes an integrated 128 GB memory card. It also offers basic alarm I/O, relay outputs and serial ports for legacy system interfacing.
The radar accepts DC or AC power (36 V DC ±25% or 24 V AC ±25%) with a modest maximum power draw (around 24 W). The recommended installation height is 2–4 m (typical 2.5 m) for perimeter applications. Mechanically it is compact and light (around 1.8 kg, dimensions 228 × 206 × 61 mm) and built to withstand outdoor exposure with IP67 ingress protection, IK10 vandal resistance and NEMA 4X corrosion rating. The operating temperature range of −40 °C to 65 °C makes it suitable for extreme climates.
Use cases and scenarios where the product excels
The Hikvision 120 m radar is versatile and delivers particular value in the following environments:
- Critical infrastructure and utilities: Power stations, water treatment plants and telecom sites often require reliable, wide‑area detection with secure evidence capture. The radar’s long reach and PTZ linkage provide automated video verification without constant human monitoring.
- Industrial compounds and logistics yards: Large open yards, storage facilities and loading areas benefit from the radar’s ability to cover long distances and differentiate vehicles from people, reducing false alarms from routine vehicle movement or environmental factors.
- Perimeter protection for campuses and estates: Universities, corporate campuses and government sites can deploy the radar to form a detection layer in front of cameras or fences, allowing early detection and automated tracking.
- Remote or unmanned sites: Where patrols are infrequent and connectivity is variable, onboard storage and automated video re‑check allow events to be recorded and verified once network connectivity or a human operator is available.
- Integration into layered security: As part of a multi‑sensor approach — combining radars, cameras, fence sensors and access control — the Hikvision radar provides a robust outdoor detection layer that triggers higher‑fidelity sensors as objects approach protected assets.
Comparisons with similar products in the market
Perimeter security solutions fall into several categories: microwave/short‑range radar, camera analytics, LiDAR and fence‑mounted sensors. Compared with camera‑only analytics, radar offers superior performance in adverse weather, darkness and low‑visibility conditions and is less affected by lighting changes. Unlike simple PIR sensors or line‑type detectors, a phased‑array radar provides spatial tracking and distance/velocity data, enabling detection over large open areas without physical barriers.
Against other radar products, the DS‑TDSB0G‑FK/120m stands out for its PTZ camera linkage and onboard video re‑check capability. Some competing radars focus solely on detection and require separate cameras or VMS to validate alarms; this Hikvision unit simplifies workflows by directly triggering and recording camera evidence. Feature‑wise, look for comparable detection ranges, scan rates and multi‑target tracking in other manufacturers’ offerings. Important differentiators to evaluate are integration protocols, onboard storage, false‑alarm mitigation techniques and environmental ratings.
Price and ecosystem also matter. At a suggested retail price of approximately $2,499, the Hikvision model is positioned as a feature‑rich mid‑range radar sensor. Buyers should compare total system costs including PTZ cameras, VMS licences and installation effort when evaluating alternatives from other vendors or a multi‑sensor architecture that pairs radars with analytic cameras or LiDAR.
Customer feedback and installer perspectives
Public, sourced testimonials specific to this model may vary by region and reseller, but general feedback from integrators and security teams who deploy similar Hikvision radar products typically highlights several recurring strengths:
- Easy integration with existing Hikvision ecosystems and commonly used VMS platforms, which reduces configuration time for installers.
- PTZ auto‑tracking and video re‑check are frequently cited as useful for reducing time spent on false alarms and for quickly verifying real incidents.
- Rugged construction and wide operating temperature range give confidence for outdoor deployments in challenging climates.
- Some installers note the importance of careful tuning and site commissioning — adjusting sensitivity, presets and zones — to achieve optimal false‑alarm performance in each unique environment.
If you're considering this radar, ask your reseller for local case studies or references and, if possible, a site demonstration or proof‑of‑concept so you can validate detection and false‑alarm performance in your specific conditions.
Conclusion — why the Hikvision 120 m radar is a compelling choice
For organisations seeking an effective, weather‑resilient perimeter detection sensor with automated video verification, the Hikvision DS‑TDSB0G‑FK/120m delivers a balanced package of range, tracking capability and integration options. Its 24 GHz FMCW phased‑array provides reliable detection for people and vehicles at significant distances, while onboard analysis and PTZ linkage reduce the operational burden of monitoring and false‑alarm management. Rugged environmental ratings and integrated storage make it well suited to demanding, remote and industrial environments.
Ultimately, the radar is best evaluated as part of a layered security strategy. When paired with PTZ cameras and a central VMS, it becomes an automated detection and evidence‑capture layer that helps security teams respond faster and more confidently. For many perimeter protection projects, the DS‑TDSB0G‑FK/120m represents a practical balance of capability, integration and cost — with a suggested retail price in the region of $2,499 — making it a competitive option for modern perimeter security deployments.
