The advances in detector technology, the reliability of wireless functionality and the development of smartphone apps have helped improve the performance and efficiency of intruder systems while also making installation of the technology even easier.
Although the components of an electronic intruder alarm have remained the same over the years, essentially a panel with triggers, such as PIRs or magnetic/vibration sensors, the improvements that manufacturers have made to the detection technology have resulted in fewer false/unwanted alarms than ever before. The accuracy of systems is no longer affected by unwanted triggers such as those by the family pet, shadows across a wall or moving bushes.
The Capture range (Grade 2 and 3) from Texecom comes with wired or wireless connectivity, wall or ceiling mounting, and a choice of detection technologies including dual-element, quad element or dual technology sensing for a variety of security environments.
With a volumetric coverage pattern featuring 42 individual detection facets, each wall mount Capture model features double the number of detection points compared to previous Texecom detectors. This optic
al system makes the detector perform to the same level as a quad PIR, and the Capture quad element detector performs higher again.
Ceiling mount models feature the same optical upgrades with over double the number of detection facets compared to previous Texecom detectors. All Capture ceiling mount models use omni-directional quad element PIR sensing for true 360° pickup while all wall mount Capture models feature a two-stage pet immunity option as standard.
In addition to the ease of installation and various features such as flexible mounting points and adjustable terminal blocks the Capture range also comes with the option to place company information and/or logos onto the devices using a printed label from Texecom under a clip-on clear cover for additional branding.
The anti-masking used in the new range of Capture Grade 3 detectors employs an infrared emitter (LED) and phototransistor (receiver) pair to detect masking events. This approach to active IR detection is superior to other methods. It is not only highly consistent in terms of performance but is also less prone to nuisance activations. The active IR technology has been adapted from proven solutions used in life-safety equipment.
Phototransistors used to receive infrared signals can be impacted by the Early effect, where performance can be impacted by changes in the voltage levels. For anti-mask applications, this means if the ambient light level increases, leading to a change in the voltage level, the sensor might signal a false masking event. To ensure that this common problem is eliminated, Texecom has implemented a new type of circuit: a Current Mirror. This ensures the voltage across the sensor is constant regardless of the light level. The result is a significant improvement in immunity to the potential impact of ambient light.
To increase accuracy and reliability in a wide range of conditions, the main anti-masking LED flash is preceded by a smaller initial flash. This Pre-Bias Dual-Flash technology eradicates issues and ensures the anti-mask function is consistent and reliable. To further filter out nuisance activations, Texecom makes use of additional output from the microwave module.
Using innovative signal processing, Capture detectors from Texecom deliver highly accurate and reliable detection, enhancing the protection on offer to medium and high-risk commercial users.
