The VX GPRS PIR Alarm System takes the market leading high stability external PIR sensor from the market leader Optex and converts it to a completely standalone security system. Powered from its own internal battery, operated by a built-in electronic key reader and communicating using the GPRS network technology
Receive Alarm Activation Alerts by Phone Call from a REAL Person, NOT a Machine!
The Wireless VXGPRS PIR Alarm System is a unique battery powered standalone security system that is controlled using high security electronic keys whilst reporting all actions to a dedicated remote secure server. This provides real time customer accessed web based event reporting and activation alerts, not by easily missed texts or automated computer voice, but from trained staff working in a certified Alarm Receiving Centre (ARC). Nothing compares to one-to-one contact with trained staff who will not only ensure that the right person has been informed and their details logged but will also offer advice about what to do next.
Monitor the PIR Alarm in Real-Time via an Online Weblog
As with all our GPRS enabled systems, users are able to monitor the activity of their systems in real time via a unique PIN code on our weblog system. Below is an example of the type of data that is available. All are colour coded for easy recognition of actions.

Use the VX GPRS PIR Alarm Outdoors or Indoors
The VXGPRS PIR is based on the market leading Optex VX402 dual Optic passive infrared detector. The detector is designed for internal or external use and offers a very high immunity to false alarms generated by both domestic pets and wildlife as well as false alarms generated by the worst of weather.
The unit is supplied with one RF remote fob, however, additional fobs can be purchased seperately. Up to 3 fobs can be wirelessly connected to any one unit at a time.
The GPRS Alarm System is Very Easy to Setup and Install
Installation and setup couldn’t be easer following the supplied instructions, detailing how to mount and set up the detector with a coverage pattern of up to 12 meters out by 90 degrees wide. Simply install the supplied battery, program in your contact numbers via our secure server and your done!
Full Programming & Device Support Provided by Compound Security Systems' Staff
All the programming of the VXGPRS PIR is completed via our secure server. All users are provided their own unique PIN access to the server. This allows full programing of the system, remote arm / disarm, timer functions etc. etc.

Ideal Environments for the VX GPRS PIR Alarm
Farm & Rural Location Security
The VX GPRS PIR has been designed specifically to be used in areas where power and communication lines are hard to reach. This essentially makes the VX GPRS PIR an ideal farm alarm system that can be located at remote entrances where intrusion detection, theft prevention and even simple presence detection are key concerns. This portable alarm system can be mounted in minutes and is small enough to remain discreet.
External Storage Areas Security
Many organisations such as hospitals and manufacturing companies use outside storage areas for hazardous materials. These are often the target of theft and are also difficult to alarm due to power and communication line access. The wireless VX GPRS PIR is an ideal and highly reliable solution for protecting access points to such areas.
Domestic & Commercial Oil Storage Security
One of the fastest growing areas of crime in the UK is theft of domestic heating oil from storage containers. Due to the variation in design of these oil storage containers, there are very few security products available to alert owners that their oil storage is being tampered with. Due to the dual beam technology incorporated in the VX GPRS PIR, oil storage tanks can be effectively protected from oil tank theft.
Driveway / Entrance Security
If you have a property where it is difficult to see when people are coming up your driveway or path, the VX GPRS PIR makes an ideal driveway alarm. Simply mount at the entrance of the driveway and the unit will notify you every time your driveway is entered, giving you complete peace of mind.
* Battery life is based on 5 communication events per day. Replacement batteries are available from multiple convenient sources and cost in the region of £10.
A Multi-Purpose GPRS Device - Can be used as a Site Attendance System
The VXGPRS PIR is perfect for remote sites that not only need security but where it is important that the individual key-holder can be identified, in this way it is also possible to use the VXGPRS PIR as a site attendance system.
The development of the VXGPRS PIR has also lead to the development of a real time monitored man patrol system comprising of a key reader and a GPRS communicator minus the detector allowing customers themselves to check they are receiving the site visits they have contracted for. Also in the pipeline, the technology is being extended to provide a wide range of standalone battery powered web based reporting detectors ranging from temperature detection, flood warning and noise pollution monitoring.
