The NEXT Duo is Visonic's single compact unit comprising advanced infrared and microwave technologies and featuring the same performance and reliability as the other models in the NEXT range. It is suitable for conservatories and garages which experience regular changes in temperature.By using digital technology, false alarms are reduced without compromising detection capabilities. Faster detection is also given, together with comprehensive all-round coverage and no dead spots, due to its optical system.
The detectors also use Visonic's 3D lenses, which are said to require less adjustment than conventional lenses, minimising installation time.

White light filter
The Scantronic 460 Twintec indoor detector from Cooper Security combines state-of the-art microwave and PIR technologies in a single unit. These combined technologies are used when the environment of the installation to be protected is very turbulent.
The 460 is suitable for home, office or light commercial buildings. Designed to fit with any décor, it is stylish, compact, robust and discreet.
Cooper says: "The 460 uses modern techniques which eliminate the many types of interference that affect reliability of traditional detectors to guarantee superior long-term performance and dramatically reduce false alarms."
It has a coverage pattern of 12m by 90 degrees that can be adjusted to suit installation requirements. Temperature compensation and an advanced white light filter are built in to minimise false alarms. Fully sealed optics provide full protection against draught, dust and insect ingress.

MaskAlert technology
The IntelliSense DT 7550CUK is aimed at high security applications, featuring dual core processing and MaskAlert anti-mask technology. With a 15 x 18m range it includes uniformity sensitivity optics, white light immunity and bi-directional temperature compensation.
No adjustment is required for two other dual technology detectors. The DT 7235 and DT 725 offer 11 x 12m and 15 x 18m ranges, giving pet immunity up to 100lbs and improved white light immunity.

Harmonic filtering
The Mirage from Texecom features a state-of-the-art PCB antenna with patented harmonic filtering techniques. It also has an advanced microprocessor core using complex software algorithms for responsiveness and reliability.
Also offered are triple independ-ent LEDs, fully adjustable microwave range, fuzzy logic signal analysis, digital temperature compensation, latch and first-to-alarm indication, neural-based environment learning, remote LED disable and tamper-proof brackets with cable feed-through.

Double protection
Double protection means double peace of mind, according to DSC. While some dual technology detectors use a secondary sensing system as a back-up, Force 2 sees double by detecting intruders with both PIR and microwave.
The unit is easy to install and gua-ranteed to work first time as it comes 100 per cent factory tested and with a five-year warranty. The detector's small size and streamlined casing blend in unobtrusively with any décor.

Top secret material!
Xeridyne has launched the QTEC XQ dual technology detector, which boasts a number of features designed to provide the highest standard of immunity from false alarms including:- A new lens material. A closely guarded trade secret, the material used has higher infrared transmission properties than any currently used in the industry worldwide, according to the manufacturer
- Design incorporates microprocessor controlled digital circuitry with software controls to screen out false alarm conditions. This is achieved using Xeridyne’s Spurious Event Rejection Algorithm
- X Engine software unique to the microwave Doppler radar processor
- Advanced quad element pyrosensor. Requiring innovative circuit design, Xeridyne was the first user of this product
- By using solid state relays the units are not vulnerable to magnetic interference
- The product has been tested in the demanding environmental conditions of Malaysia, where high ambient temperatures, humidity and frequent electric storms make PIR detection difficult
Add these advanced technical features to pleasing aesthetics, state-of the-art manufacturing and easy installation, says the manufacturer, and the QTEC XQ is well suited to all domestic, commercial and industrial systems.

Wise move
When Rokonet launched the iWISE last year the company claimed it was the “first true breakthrough in detector technology since the introduction of dual technology”.The company continued: “Providing the benefits of DT while avoiding its drawbacks, this innovation is expected to set a new standard for the industry.”
Rokonet developed the anti-cloak solution ACT, which identifies cases in which PIR detection is problematic and automatically switches to microwave-only detection. Anti-Cloak Technology concentrates only on the shape and frequency of the signal and disregards signal strength. It can identify a camouflage attempt by a moving intruder.
When the iWISE was Bench Tested in Security Installer last June our experts concluded: “The Rokonet design brief was to create an intelligent detector that is able to overcome the negating of infrared technology and this it achieves. Here is a fine product which will work well (if correctly specified) in situations which may trip up other detectors.”
