ConfiguringAlarmSystem

The PIR alarm systems as sold by http://www.inhep.co.za electronics flashes a LED on it's keypad panel everytime motion is detected on a PIR sensor. Connect an OP-Amp where the wires terminate on the alarm box. On reading 12v the signal is read by a PC which sends an SMS to your cell that a passive has triggered. Or connect each zone to a sound byte that indicates which zone has been triggered. Each time the PIR triggers the http://www.python.org program logs the event in a database. Use two seperate alarm systems if more than 10 zones are to be monitored. Or one for outside events and one for internal events.

Cheap Infrared modules stacked around all windows and entrances
Stack multiple infrared modules around a window. See ElecTronics. The modules emits a pulse at 40khz. Mass producing these modules for community use (100 pc boards min order) can be done if we all cooperate. It is impossible to breach multiple infrared modules. A StackFrame must be connected a dedicated MicroProcessor transmitting the status of each module via ["RS485"] to the base or to an AlarmBox (note get correct terminology for this).

Infrared beams on the roof perimeter
Place infrared beams on the roof perimeter. On breaching of the beam the ZoneMinder box in the centre focuses unto the area of interest.

Using 4-core alarm wire
To connect 3 PIR to one 4-core alarm wire use a PC-board with RJ-11 sockets. Connect each PIR, Infrared beam to a RJ-11 jack.

Using indoor passives outdoors
Indoor Petsafe PIR are destroyed if the sun shines on the sensor directly. Place it on a small StepperMotor and timer that keeps the passive to the back of the sun. Outdoor petsafe passives are R1200 compared to R150 for indoor petsafe PIR. They have a max range of 10m. Spacing them at 5m around a house would on average work out to 40 PIR devices at a cost of R6000. The cabling is laid via a walk-behind VibratoryPlow. These indoors won't work during the hot day but are ideal for nighttime intruder detection.

Outdoor passives are the ideal solution but it is expensive to completely cover a perimeter with them.

Everyday Practical Electronics, April 2002 has an article: Pic Controlled Intruder Alarm that can be adapted to any amount of passives. The whole circuit interfaces via ["RS485"] and RS-232 with a Python program that can SMS you which passive was triggered from a http://www.roundsolutions.com GPRS module. Connect the passive to a CctvCamera which takes a snapshot sends it to a MMS gateway server and a few seconds afterwords you receive a picture of the robber before he enters your house on your cellphone. One can only wonder why Chubb owned by the NYSE listed Tyco group a $100billion conglomorate is refusing to provide their clients with a MMS gateway server ...... It makes you think doesn't it? Why don't you phone http://www.chubb.co.za and ask them? Chubb are you people really serious in wanting to really, really solve the crime problem ....?

The alarm systems from http://www.inhep.co.za is a user interface disaster. I just want a serial port on the alarm panel so a script can configure it. Inhep for some unbelievable reason thinks that I have to learn some sort of button pushing programming language. No, all I need is a text file named alarm.conf stored under /etc and a Python script that reads it and a Sqlite database that logs every trigger from the passive, it's that simple. But apparantly not to Inhep and most other alarm manufacturers trying their utmost to annoy their customers. It is better to simply have your own built. The designing and PCB making is trivial to do. Any person reasonably competent in Atmel and PIC chips will be able to adapt the article to my specifications.

Place a tower on the farmhouse roof with camera and ServoMotor. On triggering of the passive the motor focuses on the passive and switches on the spotlight. See CctvCameras for low lux Watec CCD camera.

Use 477mhz immobilisor alarm transmitters to send a signal to the base that the PIR has triggered. This allows the use of battery packs and wireless operation.
