Earlier today I was caught off guard by a question I should have known the answer to.  I had to get the heads up from Ron Petraca, who has a wealth of knowledge about lots of things, including New York's alarm licensing requirements.  So, thanks Ron.
       The question was, is an alarm license needed for CCTV installation.
