Without a router. It is necessary that the laptop was a router handing out 3G Internet to the LAN cable that will directly link the DVR and the laptop.

Static IP on the map and the DDA.
Laptop 192.168.137.1
DDA 2 ...
At DDA default gateway 192.168.137.1

In the properties of the whistle to the Internet via this connection available to all in LAN. Exactly how is different versions of can't remember
Laptop distributing Internet CCTV is insanity originally - adella.Ste commented on June 8th 19 at 16:42
it is not necessary to be so categorical . the old laptop to the cottage instead of garbage - normal solution.
cost zero. UPS is not needed. you can put on it still evideon server. - Thomas.Swi commented on June 8th 19 at 16:45
thank you for your attention to my question. Tried as you suggest, so far unsuccessfully.
When connecting either a 3G whistle to the laptop on the laptop the Internet appears. Share the mobile Network to the Internet fell in Ethernet and therefore in the DVR. Then..
If I connect to the laptop then the Ethernet cable going from DVR - Internet on the laptop disappears, the DVR reports a failed validation gateway.
Help to understand, what other settings require and exactly how? - Harvey46 commented on June 8th 19 at 16:48
At hand now only smart phone and windows 10.
We need to get into control Panel > Network and Internet > Network connections

the whistle and the cable is already included.
On the modem - right click - properties - sharing tab
[V] Allow to use
in the drop-down list to select the network notebook

and here I forgot (no ..1.1) that the laptop assign IP 192.168.137.1
(when you keep it on it will report)

and the DDA then
192.168.137.2
255.255.255.255
192.168.137.1 gateway
CSN also handles 8.8.8.8 specify if needed - Thomas.Swi commented on June 8th 19 at 16:51
z.s. and cross patch cord instead of the usual may be required if the network in the laptop just too old. - Thomas.Swi commented on June 8th 19 at 16:54
prescribed DVRу IP 192.168.137.2 mask 255.255.255.0, and gateway 192.168.137.1
On the laptop include [V] Allow to use this Internet connection to your Local network

and at this moment Ru network card of the laptop is assigned the IP 192.168.137.1 the Internet on the laptop disappears, but appears on DVRе and DVR accesses the Internet.

Now I need to understand what should I do to the Internet remained on the laptop, because he's there too. - Harvey46 commented on June 8th 19 at 16:57
route print at a command prompt on the laptop make.
Assume that a default route not the or no.
ROUTE ADD 0.0.0.0 MASK 0.0.0.0 Ipatievskaya
perhaps another metric will have to be added to the route
when all was properly applied to the command will add the-p (permanent).
And if the output of the route print will both route,there is most likely the case
in the metrics available.

Usually the modem has a metric (priority) below the permanent network. - Thomas.Swi commented on June 8th 19 at 17:00

Metrics you can see in the route print command on operating systems running Windows. Metrics are assigned in the properties of TCP/IP, by clicking "Advanced". If checked in the "Automatic metric", the different interfaces are assigned different metric that does not always lead to the desired result when working over the network.

try to set manually. does not work, then the entrance will heavy artillery in the form
