Introduction to the GJD D-TECT 2 IP (GJD230) and its key features
The GJD D-TECT 2 IP (GJD230) is a purpose-built outdoor motion detector designed for perimeter protection where reliable detection, low false alarms and seamless network integration are essential. Combining a quad‑element PIR sensor with advanced digital signal processing and Power over Ethernet (PoE) capability, this unit offers installers and security managers a configurable detector with a programmable range up to 30 metres, an IP65 zinc alloy housing for outdoor durability and multiple integration options for VMS and IP cameras.
Key features at a glance:
- Programmable detection range— up to 30 m with configurable beam patterns to reduce boundary overspill.
- Quad PIR sensor— four element optical system with digital signal processing for improved false‑alarm resistance.
- Power over Ethernet (IEEE 802.3af)— simplifies installation by delivering power and data over a single Ethernet cable.
- Web browser configuration— remote setup and diagnostics without special software.
- Outdoor reliability— IP65 zinc alloy housing and conformal coated electronics for harsh environments.
Detailed description of specifications and benefits
The D-TECT 2 IP is engineered around a quad‑element passive infrared (PIR) sensor array and a flexible detection architecture that lets installers shape detection zones precisely. The combination of optical segmentation and sophisticated signal processing reduces nuisance triggers from wildlife, moving vegetation and environmental changes while maintaining consistent detection of human intruders.
The detector supports a programmable detection envelope out to 30 metres (typical referenced coverage up to 30 m × 30 m), with selectable beam angles that let you narrow or widen coverage to suit boundaries, pathways or defined approach lanes. This programmable approach is especially valuable on sites where you need to avoid detection beyond fences or where adjacent public areas could otherwise generate false alarms.
On the electrical side, the unit is a PoE device (IEEE 802.3af) and draws approximately 3.8 W (PoE class 1). PoE removes the need for a separate mains supply at the mounting location, simplifying cabling and enabling centralized UPS/backup power and remote power cycling. Two volt‑free solid‑state outputs provide flexible alarm triggering and can be configured for pulse counts or custom trigger conditions, making the detector easy to integrate with existing alarm panels, lighting controls or camera trigger inputs.
Network and integration features are a strong selling point. The D-TECT 2 IP connects via Ethernet (RJ-45) and supports configurable alarm reporting using HTTP, XML or raw TCP sockets. A built‑in web browser user interface allows installers and system administrators to tune detection settings, perform walk tests and view diagnostics without proprietary software. This open approach encourages integration with VMS platforms and compatible IP cameras, enabling event‑driven recording, PTZ camera call‑ups and unified incident management.
Ruggedness is addressed by a zinc alloy housing rated to IP65 and conformal coated electronics for moisture and pollutant resistance. The physical design includes pan and tilt adjustment for accurate alignment during installation, a walk‑test LED for commissioning, and dusk/24‑hour light sensing to support time‑based logic. Temperature compensation is implemented digitally to maintain consistent sensitivity across the specified operating range (−20 °C to +55 °C).

Benefits for installers, integrators and end users
Several tangible benefits flow from the D-TECT 2 IP design choices:
- Reduced installation complexity— PoE supplies power and data over the same cable, reducing cable runs and allowing power to be managed centrally.
- Lower false alarm rates— quad‑element optics and DSP mean fewer nuisance alarms from animals, headlights or moving foliage, which reduces wasted operator time and improves system credibility.
- Flexible integration— web‑based configuration and standard alarm reporting protocols make it straightforward to attach the detector to a VMS, camera or alarm management system.
- Durability for outdoor use— IP65 rating, zinc alloy housing and conformal coating help the unit withstand weather and site contaminants for reliable long‑term operation.
- Site adaptability— programmable beams, pan/tilt alignment and time/lighting sensing allow the detector to be tuned precisely for complex perimeters.
Use cases and scenarios where the product excels
The D-TECT 2 IP is suited to a wide range of perimeter and external detection roles. Typical deployments include:
- Commercial compounds and industrial sites— detection along fences, walls and access roads where early warning and camera activation are required before an intruder reaches critical assets.
- Car parks and vehicle yards— perimeter coverage and approach lanes for detecting loitering or after‑hours entry while avoiding false alarms from passing vehicles when properly configured.
- Gated entrances and driveways— targeted detection beams can cover approach lanes and activate cameras or barrier systems only when a person or vehicle is present.
- Rooflines and service areas— compact footprint and weatherproof construction make it practical to protect rooftop plant, HVAC enclosures and low‑footfall service zones.
- Integration projects— installers working on networked security systems that need PoE, remote tuning and VMS camera call‑ups will find the D-TECT 2 IP straightforward to incorporate.
How it compares with similar products on the market
Compared with basic PIR outdoor detectors, the GJD D-TECT 2 IP stands out because of its IP‑native architecture and PoE power. Many traditional perimeter PIRs rely on dedicated wiring for power and relay outputs; the D-TECT 2 IP modernizes this by integrating with IP networks and offering web-based configuration and multiple alarm reporting methods.
Against more complex radar or combined sensor solutions, the D-TECT 2 IP offers a cost‑effective middle ground: it provides better false‑alarm resilience than single‑element PIRs thanks to the quad array and DSP, but without the higher cost and regulatory considerations that can accompany microwave/radar sensors. For sites where video verification and VMS orchestration are priorities, the IP reporting options and camera integration are significant advantages over non‑networked detectors.
When compared to other IP-enabled PIR detectors, differentiators include the 30 m programmable range and the solid zinc alloy weatherproof housing. The inclusion of two programmable volt‑free outputs and multiple alarm reporting formats means it can be integrated into a wide variety of legacy and modern control systems — a flexibility not all competitors provide.
Customer feedback and installer perspectives
Official published testimonials for specific models may vary by reseller and region. In practice, installers and system integrators who choose the D-TECT 2 IP commonly highlight these practical advantages during deployment:
- Ease of installation and commissioning using PoE and the web UI, reducing site visit time and configuration errors.
- Effective reduction in nuisance alarms once beam patterns and sensitivity are tuned, improving operator confidence in alarm validity.
- Robust build quality suitable for exposed locations, with fewer service calls related to environmental ingress.
If you are considering the product, seek local references or case studies from your supplier and ask for demonstration units or trial configurations on representative site areas to validate performance under local conditions.
