· In "house hold" security systems one control system is used to operate upon multiple entrances. Therefore as the distance between the main control area and the entrance point increases, a hacker will get more choices to find easy access to the wires connecting both of them. The threats may be lessened by implementing resistor supervision, digitally managed inputs and outside digitally manipulated relays.
· Distributed circuits with smart readers may be even easier to break into for hackers if sophisticated protection methods are not implemented. Just by removing the reader from the wall an intruder can gain access to all the wiring.
