Securing HDB Electric Supply

[SteveN1 0]

Has anyone here put a lock on their outside electrical meter? Just finished a renovation and in the process of installing an alarm system and security cameras, and noticed that the entire units electrical supply can be easily turned off from the outside. Kinda defeats the purpose of having an alarm if it can be turned off by a potential thief. In fact all the electrical boxes in the block are the same. Just walk by, flip the switch and you've turned off the power to any unit.

It looks like small locks could be fitted to the covers. Not the best solution, but better than nothing.

Anyone else tackled this problem before?
