Tell us about your house and glass in any windows and doors. Are individual pieces of glass less thas one sq. foot. Maybe a DIY project is possible. I will sell you parts cost + 10% and shipping (only one guys). Prob. under $500. GE NX-8 w two keypads, 15 watt siren, 30 watt siren 5 door contacts and eight GE glassbreak detectors. If single story home it probably is very do-able. One idea would be secure windows so that one would have to break them to open or get in thru hole. One glass break can cover all glass in typical room. and you can live a reasonablly normal life in house with glass protection on. Second possibility is bidirectional motion/wall detectors. Think about a one foot wide barrier parallel to wall with several windows and a door. WITH motion on you can walk up to door let dog out but someone outside could not come thru barrier. This is one of the latest big guns in our high tech tool box. Don't recall cost on this but it is under 50 and probably closer to 30.Arrow XL
Electronics Line's revolutionary Arrow XL directional curtain PIR challenges the way security systems are perceived today. Utilizing our patented Motion Vector Analysis technology, the Arrow XL provides maximum agility and freedom of movement within the protected area, effectively replacing inferior perimeter protection solutions. The Arrow XL directional detector analyzes the sequence in which the detected signal pulses appear, thereby recognizing the direction from which the protected area has been entered. For example, if a person inside approaches a sliding door protected by an Arrow XL, the system will recognize this as valid motion and will not trigger an alarm. If, however, the Arrow XL senses motion from outside the door moving into the protected premises, it will trigger an alarm after intrusion validation. With a 9m (30ft) solid curtain vision beam, the Arrow XL is ideal for protecting display windows, skylights, sliding doors, attic entrances, and corridors. Moreover, the Arrow XL is as good-looking as it is smart, with the added flexibility of either wall or ceiling mount installation!
