What is the best CCTV system to buy?

Question

CCTV

For several days I have been looking for a surveillance system from the Middle Kingdom. For 11 k I found such a copy:
8 ch NVR,
4 x 2MP 1080 P IP camera
there is the same but with 4 ch NVR but already for 8 k.
And the main question is that I am interested in the most optimal option for 10 + -3 k (4 x 2MP 1080P IP camera + 4-8ch NVR).
What parameters should you pay attention to? Surely some of you already have better options.
If there are fresh materials where you can study this matter in detail and / or specific examples of what it is preferable to look at, tell me

Answer 1

Take the hiwatch equipment. With such China there will be a problem and not one

Answer 2

I would choose with the H.265 codec.
H.265/H.264 8CH*1080P 1920*1080 Network Digital Recorder DVR NVR 1 SATA Support Max 6T ONVIF xmeye CMS P2P Cloud CCTV

Answer 3

the proposed registrar is good in price, but please pay attention to the following factors:
1) this registrar has an outgoing bitrate limit of 48 Mbps, if you have many clients, will this be enough?
2) With these cameras, archive recording will be either scheduled (most likely this registrar supports this), or permanent. This registrar has the ability to record on a motion detector, but only on the built-in camera, integrated through the ONVIF protocol. If you optimize archive recording using a motion detector, you must use appropriate cameras, which will be much more expensive. Or use another recorder that has its own software motion detector.
3) Calculate what archive depth you need? This recorder supports one HDD, up to 8TB. If your requirements fit into this size, then there is no problem.
4) And the main question that is most often watched after purchasing equipment is applications for viewing from PCs and mobile devices. Here I would say a matter of taste, but I'm not a fan of CMS and Xmeye, I personally don't like it. P2P (the ability to connect without white IP and port forwarding) is a good thing, but it depends on Chinese servers and their mood. Those. if you set it to someone, and not to yourself using P2P access, then you will have to explain to the client why it worked well yesterday and today it is buggy and it does not depend on you.
Personally, I would prefer a registrar from the Line, it costs much more (13,000 rubles), but it is a Russian manufacturer, there is a real and Russian technical support that you can call and get advice and help with setting up. Also, the recorder has a built-in software motion detector, which allows you to save on the cost of cameras and at the same time record by motion detection, which can also play a significant role in saving disk space.
