GJD Laser-Watch® for critical infrastructure protection

Maya Georgieva — Fri, 09 Jul 2021 11:57:07 +0000

The accuracy of intrusion detection based on laser scanning makes it very suitable for securing sensitive installations. It allows the user to monitor and locate intrusions for applications where physical fences are not desirable, possible or where enhanced security is required.

Laser-Watch®- GJD515 detector is successfully used in a variety of fields such as perimeter protection, boat detection, stakeout operations, electrical substations monitoring, etc.

Boat detection

Since GJD Laser-Watch® products are designed for stable operation in harsh marine environments and the sensors work without reflectors, they create virtual fences over water surfaces or alongside the deck of a vessel. It detects all the boats that are entering or leaving the harbour in order to reduce the risk of boat and engine thefts, regardless of weather or light conditions.

Perimeter protection

GJD Laser-Watch technology guarantees high levels of detection efficiency, which remains unaffected by extreme changes in the weather. Unlike many conventional solutions that may activate a false alarm by misreading the changing weather patterns, laser detectors do not translate minor changes into potential threats.

In addition, it enables the monitoring and localisation of intrusions in areas and installations where physical fences are not desirable, feasible or where enhanced security is required. Laser sensors operate without reflectors and react in fractions of a second. Laser-Watch knows the exact position of an object.

How does the laser detector Laser-Watch® works

Eye safe invisible infra-red laser pulses are emitted from the sensor at 400Hz. If an object appears in the line of sight, it will generate reflections; the sensor detects those reflections and the precise location of the object creating them. It uses IP connectivity and very low power. Alarm settings are extremely adaptable. For example, the sensor can be set to react only on cars in a specific lane and alarm if an object has stopped or if a door opens, whilst ignoring all over activities.

GJD Multispeech Kit is used in UK healthcare facilities

Prácticas 1 — Wed, 01 Jul 2020 08:32:22 +0000

This Multispeech Kit is being used at the entrances of UK hospitals and surgeries for preventing transmission of COVID-19.

How does it work?

Activated by the GJD022 Elite PIR detector, the GJD090 Multispeech plays a pre-recorded message asking visitors to use the antibacterial gel before entering the building.

What exactly is the Multispeech Kit GJD090?

The GJD’s Multispeech Kit is a 4-channel voice transmitter module designed for intruder monitoring, access control, reception, information and alerts. A different 30-second message can be recorded on each channel or, alternatively, a single 120-second message. The volume control is adjustable and has two pre-announcement sounds.

What about the configuration?

It’s very easy to install and message recording is quick and simple.

In addition, it can be used with other detection devices such as the GJD022 Elite PIR detector, which has the custom-designed ASIC microprocessor, combined with the unique GJD optical system, which filters the information received to give the required detection accuracy at each action with options of detection ranges from 10 to 35 meters.
