How to organize remote video surveillance?

Good afternoon.

Plan to organize remote video surveillance on the property. The scheme is as follows:
Router Zyxel 4g III 4g modem megafon (since there is no way to mount optics or dsl) -> DVR (not yet decided) -> Camera (not yet decided)

A couple of questions:
1) to really get a static IP from the operator?
2) the whole system configuration is reduced to the unification of all devices in one LAN and port forwarding?
3) which applications (for PC, smartphone/tablet) fit to view the video?

Even without static if you take that brand, the type of dssl they have their apps and their cloud. Viewing is possible from any Internet.

1) Really legal. face. Or you can use ddns or similar services. Often the manufacturer of the DVR offers a dedicated and free solution, but sharpened only by their equipment.
2) Depends on your wishes...
3) When buying a DVR You will get a CD with the software.
p.s. The biggest problem is the reliability of "whistles". I don't personally know models that is guaranteed not to crash. :(
Had experience bundles of router and modem. For 3 months has worked without problems. - mireya_Lesch commented on June 14th 19 at 18:31
