Introduction to the GJD D‑TECT 3 IP and its key features
GJD D‑TECT 3 IP (GJD260)is a purpose-built perimeter motion detector that combines quad‑element passive infrared (PIR) optics with a microwave sensor and advanced signal processing to deliver reliable outdoor intrusion detection. Housed in a robust zinc alloy, IP65‑rated enclosure and powered via Power over Ethernet (IEEE 802.3af), the D‑TECT 3 IP is designed to integrate directly with IP cameras and video management systems (VMS) for seamless eventing and alarm management. With a programmable detection range up to 30 m, selectable masking and walk‑test indicators, this dual‑technology detector targets installations where low false alarms and dependable external detection are priorities.
- Dual‑technology detection: quad‑element PIR + microwave for improved discrimination and fewer false alarms
- Programmable detection range up to 30 m with selectable steps and zone masking
- Power over Ethernet (PoE) — IEEE 802.3af compatibility; typical maximum consumption ~3.8 W
- Browser‑based interface for remote configuration and diagnostics (no special software required)
- 2 × volt‑free solid‑state programmable outputs for alarm/event integration
- Rugged zinc alloy housing with IP65 ingress protection for outdoor perimeter use
- Walk‑test LED, adjustable pulse count and timer settings for tailored alarms
Detailed description of specifications and benefits
The D‑TECT 3 IP combines carefully selected hardware and configurable software to meet the demands of modern perimeter security. The quad‑element PIR provides focused thermal detection across a wide field of view, while the microwave sensor delivers doppler‑based motion confirmation. Together, these technologies significantly reduce nuisance alarms caused by environmental factors such as wind‑blown vegetation, rain, small animals or changing light conditions.
- Product code: GJD260 (D‑TECT 3 IP, 10.587 GHz microwave variant)
- Detection technology: Quad‑element PIR + microwave (dual‑tech)
- Range: Programmable up to 30 m; coverage angle variable between 10° and 70°
- Mounting adjustment: 180° pan and 90° tilt with alignment markers; optimum installation height ~3 m
- Outputs: 2 × volt‑free silent solid‑state programmable triggers
- Network: TCP/IP with HTTP, XML and raw socket alarm messaging; web browser configuration
- Power: PoE 48 V DC (IEEE 802.3af); typical power consumption ≈ 3.8 W (PoE class 1)
- Environmental: IP65 housing, operating −20 °C to +55 °C, dimensions 145 × 120 × 115 mm
- Low false alarm rate: Dual‑technology fusion requires confirmation from independent sensors, so transient triggers from one sensor alone are less likely to generate a false alarm.
- Flexible deployment: Programmable range, sliding masks and adjustable lenses let installers tailor the coverage to site geometry — from narrow approach lanes to wide‑open fields.
- Simplified networking and power: PoE eliminates separate power cabling and simplifies installations in remote or camera‑dense sites.
- Seamless integration: Native HTTP/XML alarm messaging and raw socket support enable integration with VMS, IP cameras and third‑party control systems for recording and response workflows.
- Durable for outdoor use: Zinc alloy housing and IP65 ingress protection make the unit resilient to weather and vandalism for long outdoor service life.
Use cases and scenarios where the D‑TECT 3 IP excels
The design and feature set of the D‑TECT 3 IP make it a strong choice for a variety of perimeter security applications. Typical use cases include:
For warehouses, distribution centres and manufacturing facilities, the detector can protect building perimeters, loading bays and access roads. Programmable range and masking allow protection of critical approach paths while ignoring nearby activity such as parking lot movement.
Airports, rail depots and logistics hubs require reliable perimeter protection across large areas. The D‑TECT 3 IP’s long‑range capability and networked alarm output make it well suited to feed events into centralized monitoring and VMS for video verification and incident logging.
Where nuisance alarms from vegetation or small animals can overwhelm security staff, the dual‑tech approach reduces false alerts while maintaining human detection for driveway and boundary protection.
Sites that demand high confidence in perimeter alarm reporting benefit from the detector’s tamper‑resistant housing, volt‑free outputs and integration options for redundant alarms and annunciation in control rooms.
Comparisons with similar products in the market
When evaluating perimeter detectors, installers and security managers typically compare categories rather than individual models: PIR‑only units, microwave‑only units, dual‑technology detectors and camera‑analytics solutions. The D‑TECT 3 IP sits squarely in the dual‑technology category and offers a number of advantages and trade‑offs relative to alternatives.
PIR‑only sensors can be cost‑effective and simple to install, but they are more susceptible to false alarms from environmental factors (sunlight, swaying vegetation, small animals). The D‑TECT 3 IP’s microwave confirmation reduces these nuisance triggers, making it a better choice for outdoor perimeters where reliability is critical.
Microwave sensors detect motion robustly through certain obstructions and across long ranges, but they can be triggered by movement on the far side of barriers and may suffer from multipath reflections. Combining microwave with quad‑PIR helps localize and validate human thermal signatures, improving event accuracy.
Video analytics offers rich situational awareness and identification capabilities, but it requires good lighting/visibility and can be CPU‑intensive. The D‑TECT 3 IP provides a low‑bandwidth, resilient trigger layer that can activate cameras and recordings only when a validated intrusion is detected — reducing false recordings and offloading analytics systems.
Compared to other dual‑technology models, the GJD device stands out with a web browser configuration interface, PoE support and a rugged zinc alloy IP65 housing. The ability to mask zones, adjust pulse count and set programmable timers provides installers with a flexible tool for fine‑tuning site performance.
Customer testimonials and installer feedback
While individual experiences vary by site, common feedback themes from integrators and end users for dual‑tech PoE perimeter detectors like the D‑TECT 3 IP typically include:
- Reduced false alarms:Security teams often report a noticeable drop in nuisance calls after switching from PIR‑only sensors to dual‑tech units.
- Ease of integration:PoE and browser‑based configuration simplify deployments and ongoing adjustments without needing proprietary software.
- Robust outdoor performance:Installers appreciate the durable housing and IP rating when mounting units on exposed boundaries and poles.
