Cheap Infrared modules Edit

Stack multiple InfraRedLeds around a window. It is impossible to breach multiple infrared modules. A StackFrame must be connected a dedicated AtmelMicro transmitting the status of each module via ["RS485"] to the base or to an AlarmBox

Infrared beams on the roof perimeter Edit

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

Using 4-core alarm wire Edit

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 Edit

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. The indoor PIR 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 article: Pic Controlled Intruder Alarm can be adapted to any amount of passives. The whole circuit interfaces via ["RS485"]/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 not correct from the user interface perspective. You want a serial port on the alarm panel so that script can configure it and not push buttons. 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 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 the given 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 433mhz 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. Cableplow around the perimeter with a VibratoryPlow to establish multiple DrillBoxes.

Hide PIR in long grass during day Edit

Mount PIR on pole that extends above bushes on a farm only during the night and retracts out of sight during the day. Using RadioModems a trigger event is sent to the base.

Wireless passives Edit

Use a http://www.velleman.com kit available from Electronics on the 477mhz band to receive passive signals. Each PIR can have a anti-masking ultra-sonic sensor. The 434mhz receiver kits are installed at the DrillBoxes

Microwave detection 10ghz Edit
