I guess this would be considered a tamper proof padlock as it packs a 110 dB alarm. Not sure how the alarm is triggered as the specs aren’t totally detailed. However, I like the idea. What thief wants to be tinkering with a padlock that has a loud siren going off. The US Patrol siren padlock is made of 100% aluminum and has the option of being locked with or without the alarm siren engaged. Quite a bargain at under $13 here.
