Answer
Analog cameras connected to a security DVR: The cameras can be wired or wireless (though that is a strange description because wireless cameras use more wires than wired cameras). The multi-camera DVR records video to a hard drive. The DVR can be part of the computer network and accessed remotely using a smartphone when the network is set up properly. You can also connect TVs around the house... Swann and Lorex make decent residential grade equipment.
IP Network based cameras connected directly to the home computer network. They don't store any video, so you'd need to get a dedicated computer to have the video stored for later access. In this environment, the computer or security hard drive array replaces the DVR used by the analog cameras.
In either case, the decent systems can be triggered with contact-type alarm points or by motion detection in the software or firmware - which can send you an email (assuming your smartphone can get to your email and alert you). That would be your trigger to access the system remotely to see what caused the alarm trigger...

You can use a "server" but that seems a bit overkill. The DVR acts as the "server". The better ones use an embedded Linux operating system that is optimized for this security recording task. That way you have less concern about various operating system malware exploit that look for specific vulnerabilities. And as a *nix variant, it is a much more robust environment as compared to certain consumer computer operating systems.
My 8-camera Swann system has a small 500 gig drive and can store about 30 days of best-quality video. The embedded application automatically deletes the oldest video when more space is needed. I set up the menu item to reboot once each week (takes about a minute). My smartphones can get to it. The analog "monitor" video-out connection is connected to all the TVs through the house so any of them can switch to that AV-input and see whats going on. As well, there is an inexpensive VGA monitor in the closet with the DVR for viewing the various menus and commands and options when I want to make a copy of a certain recorded sequence or if the time needs updating or some other access is needed.
If you go this route, look into getting a decent battery back-up for the DVR, cameras, network router, hub and a couple of the monitors. This way, when there is a power outage, you can still "see" and record the surveillance video.

what is the best house security camera system (outdoor, nightvision, weather proof)?
IRON MAN
iam trying to buy online which models are the best? my budjet is from $250-300.. all i need is 4 channel cameras.
i need it for house.. night vision, weather prooft, long lastings, clear view of the intruders face. and all features a regular home owner would want!..
i want to it last very long!..i dont want it to break apart like * made in china* products.
is it zmodo? samsung? swann?
thanks!
Answer
The *best* one is about 5x your budget. In your price range are essentially entry-level. Personally, I like Swann and Lorex.
"Clear vision of the intruders face" means the intruder is posing for the system. That is not how these systems are designed - and for your budget, that sort of quality is just not available.
And your budget does not allow us any IP cameras (1 decent outdoor IP camera would be your whole budget with nowhere to store the captured video).
I looked at the Zmodo equipment - good features, did not like the build quality and have stayed with Swann and Lorex for residential installations. The cameras that come in the 4-camera kit will not last a long time - I have found the cameras in the $150 range work and seem to last well. We don't know what sort of outdoor weather your cameras will need to endure. Those I install are usually under the eve of the roof and not in direct sunlight or direct rain/snow.
By the way, all these electronics are "Made in China", but it seems Swann and Lorex have more strict build requirements with regard to better components which is probably why they seem to be "better" (in my opinion, anyway...)
I just installed one of these

The extra 4 channels are there, "just in case"...
