I own my own business and got hired by a client who needed people who knew how to work security cameras. I didnt think it would be that hard. They needed security cameras for a national card game held 3x a year in different places all the time. They wanted us to watch or catch possible cheaters or disprove a cheater. I started out with 4 cameras.It was amazing. Loved how it could really zoom from far away and the picture quality. I could read people's suits in their cards from 100 feet away. But when I upgraded to 8 cameras,it started to become a problem.Using the DVIEW CAM program,8 cameras started to freeze or cut out.I was also using a dlink DIR 450 router and had a sprint air card attached to it(since it is what they recommended to use with these cameras)but what they failed to mention is that the more cameras you have,the more problems you will have too.The sprint air card(and any other aircard you buy)only provides a limited bandwidth.And to divide that to 8 cameras will really decrease it a lot which will then give you an unstable connection.The only way for me to solve this is to have a solid internet connection like comcast internet.But since I am always mobile with this system,I cant do that.I wish I knew that before I spent 4 additional cameras.Now I have to buy another router and air card and laptop to split 8 cameras into 2. Their tech support will take you hours. When you first call, you will be helped by a novice and if they cant help you, will transfer you to a higher level tech support, and if they cant help you wil transfer you to another higher level tech. They are quick to say that a product is defective even if it isnt. So you want to be sure you did everything you can. I know more about these cameras than I want to know. I had to change settings for the cameras, the router, ports, static IP's and everything technical. Also, make sure the computer you use is a 32-bit operating system because this is NOT compatible with 64 bit. Anything more than 3GB RAM will be 64 bit.
