Audio cameras in common areas

[Sami Gren]

hi, 

I want to install security cameras with audio in a building  in Essex County nj.

Someone claimed that if I put on audio, by law I need to post that in building. 

Is anybody familiar with laws of cameras?

I thought we had it bad in NY, until I read some of the posts from you folks doing business in NJ.

So, lemme get this straight - if I put up a camera on MY property in plain view, indoors, in a common area, and post a sign that says "area under audio/video camera surveillance" or something similar, and I record one word of audio (or a pair of hearing impaired folks signing in my lobby), I can be arrested?

But if a tenant trashes your rental unit and steals all the appliances and you call the cops in NJ, I'll bet dollars to doughnuts (!), that they'll say it's a civil matter...
