Guest sprog Posted November 13, 2006 Posted November 13, 2006 Having always been a tinkerer and up for a challenge, I'm setting out on a new venture! My goal is to design and build, from the ground up, my new home security system. My current objectives are: - PC Control and Monitoring with remote control access from any net equipped device. (Can easily do this securely) - Self contained control unit in case of PC failure. (Likely based on PIC microprocessor(s)). - Capability to add a variety of sensors from PIR to Temperature/Motion/Active IR/whatever. - Capability to add camera's with face recognition algorithms/Biometric sensors. (Particularly usefull at the front door as a "Friend or Foe" system). I'm sure the feature list will grow a bit as I draw up basic designs. However, I could use a little input right now from anyone "in the know". I am looking for some sensors, initially just PIR ones with specifications in terms of input voltage, output signal type (analogue strength or digital "detected/not detected") and ideally fairly low cost. I'm working on a website which will "Blog" the project for anyone who wants to follow I'll post the URL shortly.
Guest sprog Posted November 13, 2006 Posted November 13, 2006 Other information that would be usefull: What is the current "hot technology" in security systems? What kind of issues are commonly encountered and cause the biggest headache? What is most of your (professionals) time spent fixing? If you could make one change to your favourite system, what would it be? Don't hold back here. I'm after design ideas. Even if it sounds ridiculous! (Ok, a system that goes and does the shopping may be overkill, but I'm after ideas here).
arfur mo Posted November 13, 2006 Posted November 13, 2006 Other information that would be usefull:What is the current "hot technology" in security systems? butane powere soldering irons, or a fully charged and shorted 12 amp battery )- smoking technology that is). What kind of issues are commonly encountered and cause the biggest headache? unsecured high level external bell (edited - public forum) nearly killed me! What is most of your (professionals) time spent fixing? (edited - public forum) If you could make one change to your favourite system, what would it be? ATM fited to front so when job is done i get paid promtly, would have a B.P.F (Bad Phrase Filter) so "the cheque will be in the ost on the next cheque run' will be deleted from the lying excuse bank Don't hold back here. I'm after design ideas. Even if it sounds ridiculous! (Ok, a system that goes and does the shopping may be overkill, but I'm after ideas here). no probs, but just don't marry it seriously sprogs, the market is infested with 'clever' security systems, just hunt around the internet, from those that are intruder systems and wanna be fire alarms or access control and visa versy. to be honest there is a point where system integration is just total degeneration, the calls on such schemes often require vastly different equipment as well as installation technique's, and best along with a deep understanding of each technology to get reliable operation. place that thought against some guys who have been in intruder or fire only for many years, and still manage to cod's it up. by all means have some fun, grab your 'building blocks' off ebay, bolt them together and enjoy the b-b-q that might follow, but if this is a serious idea/project i would advise against it. put it this way, you buy a hi fi system it has the usual cd player, radio, tape decks and plynth, one fault on the amplifier and everything is very very silent, so lesson learned not to put too many eggs in one basket. transpose this to you automation, you could have your windows and garage doors openning and closing to he strains of swan lake at 4 in the morning, much to the bemusment of you neighbours. if i were going down this route i would base designs on a pc and a pic 'blower', that way you can mod the program or tweek your idea's. regs alan If you think education is difficult, try being stupid!!!!

Well if you are looking for a panel which can be interogated via a p.c my obvious choice would be a galaxy,but i have to agree with previous comment it is a hard task for some one not in the trade...good luck though
Guest Posted November 13, 2006 Posted November 13, 2006 What is the current "hot technology" in security systems? refinement of what we had 15+ years back What kind of issues are commonly encountered and cause the biggest headache? Subscribers, APCO ACPO (come on Mr Happy let's get it right!) ect..... e the biggest headache?What is most of your (professionals) time spent fixing? alarms If you could make one change to your favourite system, what would it be? links (theve have converted me ) Don't hold back here. I'm after design ideas. Even if it sounds ridiculous! can all be done of the shelf with any half decent set of controls expect maybe.... Capability to add camera's with face recognition algorithms/Biometric sensors. (Particularly usefull at the front door as a "Friend or Foe" system
norman Posted November 13, 2006 Posted November 13, 2006 - Capability to add camera's with face recognition algorithms/Biometric sensors. (Particularly usefull at the front door as a "Friend or Foe" system). Nothing is foolproof to a sufficiently talented fool.

Guest sprog Posted November 13, 2006 Posted November 13, 2006 Few interesting ideas. William of Occam once said "one should not increase, beyond what is necessary, the number of entities required to explain anything". I'm a firm believer in the marrying of technology and the KISS principle (Keep it simple, stupid). What I have observed to date is a few systems are very plain, basic and don't do much other than ring a bell if a sensor is triggered. At the other end of the scale are the hugely expensive hi-tech supposedly integrated systems. However, I have yet to see a modular expandable system targetted at the home consumer with a realistic price tag and the features listed above. I guess I should add to the "requirements" that as well as being secure, it should be easy to maintain and operate both from an "Engineers" perspective and the users. As for e-bay, well I'm not a believer personally I prefer to use products straight from the manufacturer when prototyping - less chance of some incompentent frying them with a few 1000 volts of static and sticking them up on a 99p auction...
Guest Posted November 13, 2006 Posted November 13, 2006 What I have observed to date is a few systems are very plain, basic and don't do much other than ring a bell if a sensor is triggered. in your gaff you have an old 09100 right? At the other end of the scale are the hugely expensive hi-tech supposedly integrated systems. which will cost a wee bit less than the 9100 costed when new........
Guest sprog Posted November 13, 2006 Posted November 13, 2006 in your gaff you have an old 09100 right?which will cost a wee bit less than the 9100 costed when new........ That's probably a good question to ask actually. What is a rough figure for a high end (galaxy or similar) system with PC software, say 5 PIR's, Carbon Monoxide & Smoke detectors and a couple of cameras? (including or excluding installation but specify which please)
