We spoke on Thursday, they said "We will try and have someone out tomorrow". It's now Wednesday and radio silence.

Cost of the industrial quality CCTV HD (4 times larger capacity than the original HD) was $150.00!!! Works great !!!

I will never use anyone else so I really hope he doesn't win the lottery anytime soon. He itemizes and estimates well and clearly.
