<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
