A customer submitted this ticket today:
Michael programed my cameras system today (13 ip 1.3 mp) and now my internet is extremely slow. This is both when logged into the cameras from home and when logged off and not viewing cameras.

There are only 3 ways to avoid this bandwidth consumption without reducing the quality of the video from the cameras. Each IP cameras at the highest quality setting will require between 3-4 mbps of bandwidth. So 13 cameras will consume between 40-50 mbps of bandwidth. If you only have a standard network, then it will only support a maximum of 100 mbps and typically you should assume that you will only achieve 50% of the advertised bandwidth. Basically you are maxing out your bandwidth with the 13 cameras. When you are accessing the cameras remotely, either inside or outside the network you are using even more bandwidth. For 13 cameras, we recommend you set up a separate dedicated network for the cameras. If this is not something you want to do, then you need to convert your network to a gigabit network which will provide you with 10 times the available bandwidth. This is fairly simple to do. Just replace any switches and routers with Gigabit devices. The last option is to switch to an edge server configuration where you have cameras in close proximity connected through the network to nearby NVRs which will limit the bandwidth travel over your network to short distances. When you connect remotely, be sure to connect only to the substream to reduce the bandwidth consumption as well. Still, my recommendation is for you to have a dedicated network for your cameras.
