Question 5

Can I have 2 or 3 of these (total of 8 or 12 cameras and 2 or 3 dvrs) set up on the same network and be able to see all cameras via smart phone and interenet?

Accepted Answer

Yes , you can have 2 or 3 of these (total of 8 or 12 cameras and 2 or 3 dvrs) set up on the same network. 
Each DVRs will be assigned an IP address separatedly

I've never be able to see all my camera via smart phone 'cause
I couldn't do forwarding port on my AT&T Router.
But I use TeamViewer or Chromecast to access a PC at home and watch all my cameras from there by going to the IPs assigned to those DVDRs.

Question 6

Does this system send out email alerts in real time?  It doesn't mention it specifically in the information here on the page but it seems like a common feature on similar products.

Accepted Answer

Yes, I have it set up to email me immediately with 3 still pictures attached. I have it send using an email address only used for security systems, and have that email address filtered into a security group in my gmail. I then set my phone to make a special alert sound when an email with that label hits my inbox.

TL;DR Anytime someone is at my front door, within 6 seconds I get an alert to my phone accompanied by still pictures.
