Storm

Hello new to the forms I would like some advice on a security camera system for my home on the outside could anyone recommend a good system for 500.00 or less. I would also like it to include the DVR. Is it also possible to set up the system so only devices connected to my home router can use the remote user log in? Also since the dvr is hooked up to the router does it use a lot of bandwidth? I would like the camera’s to be wired. Thanks for any advice.
