Well I presumed that it was just the reader and the LED but if someone got into it could they send serial down one of the wires or something to get it to open. I presume even if this is the case you would need to know the code to be able to send it so you might as well program your own card.
I presume from this analysis, there is no way someone can electrically 'brute force' open the door that you know of by using the connections that there are outside.
Yes if some one opened the outside box and somehow manipulated the rfid reader and figured out which pin was the rx and then some how hooked up to that and then spoof a valid RFID tag that I have in the system...they could gain entry... I suppose...
but for all that the bad guy wouldnt even need to open the outside box...they could just spoof a RFID tag that I have in the system
...then if we explore that even a little further...we could say this is true for ANY of the professional RFID door entry systems out there on the market.
suffice it to say I feel rather safe about it.
The lock itself is activated trough a solenoid, right?
I wonder what'd happen if someone put a really high voltage trough it. Would it blow the entire system up? Would it unlock the door somehow? Or nothing would happen?
Yes. You are correct. the door lock itself is a solenoid. This model of the door lock is a "fail secure" version. that is to say if power is lost or if someone electrically blew it the hell up (which they would need to be inside already to do) it would fail secure. AKA - locked.
