<Blacklotis> alrighty <Blacklotis> here we go <Blacklotis> last time we talked about all hardwire systems <Blacklotis> where you have to physically run a wire from your panel to a door/window <Blacklotis> now what happens if its either not possable, or the customer simply doesnt want wires all over the place? <Blacklotis> there is a neat litle noption on most newer systems to have a wireless device <Blacklotis> now, im going to go over this in sectios <Blacklotis> first I will discuss the types of wireless devices, as I did before with teh hardwire ones :bonusbug!bbug@bu-6459CBA7.l.pppool.de PART #lecture <Blacklotis> then I willl talk more about the methods involved in how they communicate with the panel <Blacklotis> finally I am going to go over how the panel relays wireless data to the central station <Blacklotis> any questions so far? <Blacklotis> none? <Blacklotis> alrighty <Blacklotis> now, basically wireless is almost the same as hardwire <Blacklotis> astetically the only differance being that the hardwire contacts are usually small enough to hide inside a door frame <Blacklotis> not so with wireless <Blacklotis> the contacts are usually about the size of a flash drive, with a bit more gurth <Blacklotis> and the magnets are a bit larger as well <Blacklotis> the motion detectors are about the same size <Blacklotis> so, how do they work? <Blacklotis> well, if you couldnt tell, they are battery operated <Blacklotis> the ones i use run off a 3.6v lithum battery, which will last anywhere from 5-7 years <Blacklotis> ok, so now we know how they are powered <Blacklotis> so what the heck do they do? <Blacklotis> its simple really, they do almost exactly the same thing a hardwire contact does <Blacklotis> reports to the panel when the magnet is removed from the contact <Blacklotis> simulating a door/window opening <Blacklotis> the motions work off the same ideas as hardwire ones also <Blacklotis> IR beams that need otbe triped in order to set off an alarm <Blacklotis> questions? <Ch4r> yeah <nullLink> Same. <nullLink> Ch4r you first please. <Ch4r> why do the most idiotic people always IM me when I'm trying to attend a lecture? <mu-tiger> :P <Blacklotis> hmm, ask the idiots :) <CcSsNET> ^.^ <Ch4r> ok <Ch4r> nullLink, go ahead ;) <nullLink> Lol <nullLink> Anyways, I was wondering I'm sure your going to cover this, But do they use the normal 802.11 or something else? <Blacklotis> its its own protocol <Blacklotis> every panel is different <Blacklotis> all propriotary <nullLink> Okay <Blacklotis> anyone else? <Blacklotis> ok, lets plug on shall we <Blacklotis> now, here is the biggest thing during this lecture <Blacklotis> HOW in fact does the panel and the device communicate <Blacklotis> last lecture we never discussed wireless recievers, so thats where im going to start <Blacklotis> for now just think about the contact transmitting a signal through the air anytime it is tripped <Blacklotis> its up to the panel to catch that transmission, interpret it, and respond accordingly <Blacklotis> in order to catch it there are a few options :bic!biC_@bu-87078F5F.sea2.cablespeed.com JOIN :#lecture <Blacklotis> there are what we call RF keypads <Blacklotis> which stands for Radio Frequency <Blacklotis> there are also recievers that wire directly into the panel, on parallel with a kaypad <Blacklotis> keypad* <Blacklotis> both simply recieve data and send it to the panel. <Blacklotis> questions? <CcSsNET> i got one but its not covered yet, or maybe it was in the last lecture <Blacklotis> ask and ill let you know <CcSsNET> card readers and the cards <Blacklotis> thats a whole other beast <CcSsNET> ok nvm then <CcSsNET> continue <Blacklotis> card access systems are an entirely differeny system <CcSsNET> ok <Blacklotis> alrighty <Blacklotis> now that our panel is capable of reading signals, how does it know which contact is which? <Blacklotis> well, each contact comes prefab with a serial number hardcoded into it <Blacklotis> most are about 7 hex digits <Blacklotis> but ive seen as high as 9 <Blacklotis> now, when someone is installing the system <Blacklotis> they have to manually program each contact into the panel on what we call zones <Blacklotis> a zone is simply each individual opening or group of openings as it appears on the panel <Blacklotis> for instance <Blacklotis> lets say I have a house with a front and back door, and one window <Blacklotis> chances are I would loop together the back door and window, since they are both perimeter openings <Blacklotis> and leave the front door on its own zone so it will be known specifically to the user when it is open <Blacklotis> so lets say I am now a user. I go to my keypad and I see that it says: zone 2 open <Blacklotis> I know that is either my back door, or my window, wher as zone 1 is ONLy the front door <Blacklotis> questions? <Ch4r> nope <Blacklotis> bunch of geniuses tonight! <Ch4r> lol <Blacklotis> im impressed <Blacklotis> anyways <cleric> Well I came into the middle of it, so i'll wait to ask questions later. <Blacklotis> plug on I shall! <Blacklotis> now, on MOST panels, only hardwire contacts can be on the same zone <Blacklotis> ive never seen one to the contrary but im not going to say one doesnt exist <Blacklotis> so, if the back door had to go wireless <Blacklotis> I would now have zones 1-3, front door, window, and back door <Blacklotis> with 3 being the wireless <Blacklotis> again <Blacklotis> questions? <Blacklotis> well, thats the major part of that section. Now its on to how the panel reports the contact information to the central station <Blacklotis> there are a few different reporting formats in use today <Blacklotis> one being contact ID, which will report the ID number of the contact in specific. Another is zone reporting, which makes the wireless look just like hardwire <Blacklotis> I personally use zone formatting, so it all comes up as zone numbers <Blacklotis> which is much easier for both the user and the operations at the monitoring station <Blacklotis> questions? <Ch4r> not here <Blacklotis> alright, so I believe someone asked as to protocol <Blacklotis> I know only the basics here, because ive never had to actually debug one <Blacklotis> basically, the transmitter will encrypt its serial number, how I have no idea <Blacklotis> and the reciever is capable of decrypting it, again I have no clue as to algorithms <Blacklotis> damm, that was the wireless lecture <Blacklotis> haha, I was expecting a million questions like last time <Ch4r> lol <Blacklotis> any questions anyone? <Ch4r> not from me.. <Blacklotis> alright, well lets go ahead and break into lecture # 3 then <Blacklotis> this one is going to cover some programming, and basically what kind of information is programmable into a panel, and what you ahve to do to get at it <Blacklotis> actually, I lied <Blacklotis> lets change that up a bit <Blacklotis> alright, im going to go ahead and go more in depth as to how certanin devices work <Blacklotis> motions in particualr <Blacklotis> as well as ways to get around them <Blacklotis> a fallacy if you will <Blacklotis> ok, motions are all well and good, but what if someone has a pat, and the pet needs to walk around at night? <Blacklotis> obviously we cant have pets tripping motions all night <Blacklotis> so, we have what we call PIR's <Blacklotis> Pet immume motions <Blacklotis> basically <Blacklotis> now how do they work <Blacklotis> im going to cover one of the more advanced motions I have seen, because it has all the functionality <Blacklotis> there are a few different things the motion is looking for besides the tripping of the IR beas <Blacklotis> beams* <Blacklotis> first off, if the motions senses motion below a certain range (3-4 feet) <Blacklotis> its going to compare the image it sees to one in memory <Blacklotis> these motions are no longer looking in 2d <Blacklotis> this motion is actually capable of taking a 3D image of whatever it is looking at <Blacklotis> by bounding certain types of things around the room <Blacklotis> sound / IR /depends on the motion <Blacklotis> think of it like echo location <Blacklotis> anyways, the motions will take the image they see, and compare it to ones stored in memory <Blacklotis> and if its a pet, discard it <Blacklotis> questions thus far as to the motions? <Ch4r> nope, I'm with you <Blacklotis> alrighty <Blacklotis> now, I believe someone else asked las lecture <Blacklotis> and if they didnt Ill bring it up anyways <Blacklotis> what about heat and cold? <Blacklotis> changes in temprature can make the air move <Blacklotis> which can make a motion false <Blacklotis> so, these motions also detect heat in a few different ways <Blacklotis> twhen someone walks into a room, it can see a thermal image of the person, which it compares to the walls of the room <Blacklotis> if you ahve ever seen a thermal image, you know that blue is colder than red <Blacklotis> it will basically see the shape of a person in red walking around a wall of blue <Ch4r> nifty <CcSsNET> interesting <CcSsNET> question <mu-tiger> i got one, when it's my turn <CcSsNET> can these things tell exact position in a room <Blacklotis> yes, but it really doesnt matter <CcSsNET> and i tried typing something a min ago im guna repost it <Blacklotis> if there is motion, it doesnt matter where <Blacklotis> its just looking for motion <CcSsNET> i work somewhere that has little octagon sensors on every ceiling of every room with a little green light that blinks or some of them the octagon thing turns red durring movement <Blacklotis> the motion im describing isnt a standrd motion <CcSsNET> ah ok <Blacklotis> the standard ones are not so advanced, but im still talking about residential equipment <Blacklotis> this is all avaliable to any alarm company <CcSsNET> ok <Blacklotis> go ahead mu <mu-tiger> two questions or three <mu-tiger> not sure yet <mu-tiger> but, is the resident's motions also stored in mem? <Blacklotis> you mean, are the peoples image stored in memory? <mu-tiger> yes <Blacklotis> ok, maybe I explained not enough <Blacklotis> there is not an exact image of each per /person <Blacklotis> it has general images pre programmed into it <Blacklotis> as to what a dog SHOULD look like <Blacklotis> or what person SHOULD look like <Blacklotis> answer your question? <mu-tiger> ok, then how is that not self-defeating, if a stranger breaches the sensor? <CcSsNET> its probably very dynamic the way the sensor recognized an object <Blacklotis> well, when the alarm is set <Blacklotis> any motion trips it <Blacklotis> when its not set, it doesnt matter <mu-tiger> including a resident's? <mu-tiger> i'm confused <Blacklotis> no motion makes any differance when the alarm is not set <Blacklotis> when the alarm is set <Blacklotis> ANY motion that is not a pet <Blacklotis> will trip it <Blacklotis> so yes, the resident will trip the motion <mu-tiger> so if you have to go pee, you turn off the alarm? <Blacklotis> or dont have the motions on at night <Blacklotis> only the doors and windows <mu-tiger> =/ <mu-tiger> ok <Blacklotis> but yes, you would ahve to turn it off if it was on <mu-tiger> is there a remote? <Blacklotis> motions are generally used when people leave <Blacklotis> there are in fact remotes yes <mu-tiger> ok <mu-tiger> i'm done <mu-tiger> ty <Blacklotis> alrighty :) <Blacklotis> now, I was mentioning a person walking around <Blacklotis> that is another way the motions sence movement, the red contrasting on the blue <Blacklotis> so to recap, we have: <Blacklotis> 1) infa red beams <Blacklotis> 2) 3d imaging <Blacklotis> 3) heat <Blacklotis> 4) pre programmed targets <Blacklotis> all helping the motion decide how to react <Blacklotis> as you can see, these things get much more advanced than first meets the eye <Blacklotis> there is one flaw I have found with ALL motions though <Blacklotis> they will not see through glass <Blacklotis> so, if you are outside a store window <Blacklotis> a motion will not detect you, no matter how much you walk around <Blacklotis> before you all get happy thinking that you can just walk around with a big piece of glass <Blacklotis> remember the heat and 3d imaging <Blacklotis> which is a large reason for why those exist <Blacklotis> questions? <CcSsNET> well what if <mu-tiger> so proprietars <mu-tiger> go on CcSsNET <CcSsNET> you had a very cold piece of glass <CcSsNET> then it would be 3d imaging left no? <Blacklotis> and the heat radiating from your body <CcSsNET> true <CcSsNET> ok nvm <CcSsNET> your right about the sensors not sensing threw glass though <CcSsNET> i notice that all the time at work <CcSsNET> offices and such <mu-tiger> so, what do proprietars do? just get the cops to cruise by every so often? <Blacklotis> neat <Blacklotis> ? <mu-tiger> business owners <Blacklotis> the police would be called if the alarm went off <mu-tiger> =/ <CcSsNET> for buisness's it depends if a gaurd is present <mu-tiger> i mean if someone were casing <Blacklotis> ah <CcSsNET> if a gaurd is there the gaurd is called first, second call if no awnser then the cops are <Blacklotis> no, most of them dont work like that <Blacklotis> they call the monitoring station first <Blacklotis> who calls the police as well as the busisness owner and their contact list <Blacklotis> I thought we went over that last time? <Ch4r> yeah <Ch4r> we did <CcSsNET> well the monitoring station is the one that knows in the first place and there the ones making the calls <Blacklotis> yes <mu-tiger> but if there's no guards <mu-tiger> the only time the cops are called is if the alarm is tripped <CcSsNET> im a security gaurd btw <CcSsNET> lol <mu-tiger> if someone's casing at night <Blacklotis> what do you mean, casing? <mu-tiger> and not MESSING <mu-tiger> like, walking around outside <mu-tiger> looking for vulns <mu-tiger> not touching <mu-tiger> just looking <CcSsNET> o ok <Blacklotis> then no, nothing is going to happen <Blacklotis> but <Blacklotis> keep in mind <Blacklotis> most motions are indoors <mu-tiger> that's why they have security cams <mu-tiger> ok <Blacklotis> and there is not always glas fronts to places <mu-tiger> go on <Blacklotis> security cameras are again, another fiels, maybe ill do a lecture on them as well as card access sometime <Blacklotis> field* <mu-tiger> ok <mu-tiger> ty <Blacklotis> alrighty <Blacklotis> so now we know some more about motion <Blacklotis> contacts are simple, on and off <Blacklotis> nothing special <Blacklotis> smoke is the same <Blacklotis> nothing special, detect smoke, sound the alarm <Blacklotis> did I talk about glass breaks last lecture? <Ch4r> nope <Ch4r> I don't think so <Blacklotis> ok <Blacklotis> there are a few types of glass breaks <Blacklotis> all detect the breaking of glass <Blacklotis> the old ones used to be a bunch o foil, which acted as if it were a wire, and if the glass broke, so did the foil, which broke the circuit <Blacklotis> the foil was on the glass <Blacklotis> more advnaced ones use tone to detect the sound of breaking glass <Blacklotis> it simply listens for a certain frequency range <Blacklotis> and trips it if the range is heard <Blacklotis> questions? <mu-tiger> hrm <mu-tiger> what if someone used a glass cutter and suction cup? <Blacklotis> these things trip if I tap my keys on the glass <mu-tiger> ok <Blacklotis> they are over sensitive <Blacklotis> ive even seen a glass breaking on a TV show trip them :) <CcSsNET> nice <Blacklotis> beacuse it sounded close enough <mu-tiger> damn <mu-tiger> that'd be annoying <Blacklotis> indeed <Blacklotis> ok, so now we know some more sensors <Blacklotis> lets talk about programming now <Blacklotis> this is really why the installer knows more than the user, and what seperated the two <Blacklotis> the ability to get into panel programming <Blacklotis> and knowing what to do once you are their <Blacklotis> there* <Blacklotis> unfortunatly <Blacklotis> there are literally hundreds of types of panels out there <Blacklotis> so going into specifics as to how to program one is really a waste of time, unless you actually go install one <Blacklotis> but <Blacklotis> generally im going to just show whats possable <Blacklotis> now, there are codes that turn alarms on and off <Blacklotis> there is a mster code, which is used by the main user <Blacklotis> a user code, often times given to a maid <Blacklotis> and an installer code <Blacklotis> the installer code has both more and less power than thge master code <Blacklotis> if you turn the system on with a master code, usually the installer code is not capable of turning the system off <Blacklotis> to prevent your installer from robbing you <Blacklotis> but, most of the time, the installer code can reset all codes <Blacklotis> so if your alarm is turned off, and somone knows how, then can reset or aff a code to your system <Blacklotis> add* <Blacklotis> questions? <Ch4r> not from me <mu-tiger> nope <Blacklotis> ok, so now we know the installer code, which ADT's standard is **** <Blacklotis> yes I did that on purpouse <Blacklotis> anyways <Blacklotis> bad humor sorry <Blacklotis> now we know the instaler code <Blacklotis> so we need ot get into system programming <Blacklotis> this is only avaliable once the system has been turned off <Blacklotis> as in not armed <Blacklotis> and only accesable usign the installer code <Blacklotis> now, we go ahead and get into programming <Blacklotis> what the heck can we do now? <Blacklotis> well, most panels have a system of fields set up <Blacklotis> where each field has certain bits of data which tell that panel what to do <Blacklotis> lets say for instance field 41 (*41) is the phone number to callcentral station <Blacklotis> we can go ahead and get into field 41, and change the phone number <Blacklotis> everyone following so far? <mu-tiger> yes, and you said all this is done in hex? <Blacklotis> certain fields are in hex <Blacklotis> most are done in decimal <mu-tiger> ok <mu-tiger> i'm good <Blacklotis> reporting options are usually hex <Blacklotis> but its panel specific <mu-tiger> oh? <mu-tiger> what kind of options? <mu-tiger> for example? <Blacklotis> as in weather or notto report <Blacklotis> im getting there next <Blacklotis> ;) <Blacklotis> ok, mu brings up the next part of programming <Blacklotis> zone programming <Blacklotis> this is where the zones are basically created <Blacklotis> you can specify reporting options, which ill cover ina minute <Blacklotis> the type of zone, weather its an entry exit zone, or a perimeter, motion, smoke. . . .etc <Blacklotis> and eather or not it is a wireless zone <Blacklotis> if it is further programming is needed <Blacklotis> ok, now reporting options <Blacklotis> lets say you dont want a certain zone to call central station when it goes off <Blacklotis> you jsut want it to set off the siren and make all kinds of noise <Blacklotis> you can go into zone programming and zero out the repoting options, which makes it a "local zone" or one that wont report <Blacklotis> questions? <mu-tiger> why would you do that? <Blacklotis> if you have somehting you dont want to report <Blacklotis> for instance <Blacklotis> ADT has said that wireless remots are no longer allowed to report <Blacklotis> because they got too many flase alarms on them <Blacklotis> after novermber 15th of 2005 installers were told to make them local only <mu-tiger> hrm <Blacklotis> I can still make them report, and ADT wouldnt be able to tell the differance <Blacklotis> but we were told not to <mu-tiger> i bet that makes rich homeowners happy <Blacklotis> well, when something reports <Blacklotis> ADT gets teh device type <Blacklotis> which is mainly used for wireless <Blacklotis> and they get the signal type <Blacklotis> so if I program it as a normal signal <Blacklotis> I can make it report with them not knowing the doifferance <mu-tiger> hrm <mu-tiger> so my old dude neighbor needs to be aware of this, if he's wireless <Blacklotis> how long has he had it? <Blacklotis> if it slonger than november 15th of 2005 its alreadty reporting normally <mu-tiger> ok <mu-tiger> yeah, he's had it a few years <Blacklotis> ok, no worries then <mu-tiger> i'm done, ty <Blacklotis> alrighty <Blacklotis> alright, those are the major parts of programming, usually the installer code can only be changed from programming <Blacklotis> meaning you need the code to change the code <Blacklotis> actualy, if no one else has any significat questions <Blacklotis> or anything else they want to know. Thats pretty much ALL of the securiy information I was planning on sharing <Blacklotis> we have gone over hardwire/wireless/and programming <mu-tiger> hrm <Blacklotis> as well as some more <Blacklotis> and how it all works <mu-tiger> well <mu-tiger> in wireless <Blacklotis> the rest of the information is much too panel specific to get into <mu-tiger> again, the signals can be scrambled? <Blacklotis> like I said last lecture. The only time I have seen them scrambeled was a large van filled to the brim with equipment <Blacklotis> and all it did was block them <mu-tiger> ok <mu-tiger> i'm good, then <mu-tiger> thanks
