A very large amount of traffic is leaving the IP camera, how to fix it?

Question

Mikrotik

Good afternoon!
I have a Mikrotik and a HiWatch DSl250 camera in my hands, all this is located remotely and is connected to the registrar in the office.
The camera works through a microt from a Beeline USB modem, the traffic is allocated from the operator for 50GB, but the problem is the following.
In 3 days, these 50GB have disappeared, in detail, it can be seen that every 40 minutes the same number of packets of 400MB is leaving, tell me where to look in which settings, registrar or camera?
no one else is powered to the microt router.
The resolution to the camera is 704x576 the main stream, and it is connected to the registrar through the webcam port (80 or 8000)

Answer 1

It is necessary to look not at the resolution, but at the bitrate. It can be set adequately, but it can be - not quite.
A 1 MP picture (1280x720) with a rate of 25 fps, clamped by the H265 + codec, with an average scene complexity, weighs 832 kbps. Data from the Hikvision calculator. We consider - 832 * 60 * 60 / 1024 = 2925 Mbps, divide by 8 more, we get 365 megabytes per hour. You have a resolution of 0.3 MP, that is, it must be about 3 times less.
In general, the description of the problem is strange - you cannot set such a resolution on this camera! For the main stream, at least 1280x720, and for the secondary, a maximum of 640x480.

Answer 2

H265, less keyframes.

Answer 3

That is, the camera is located remotely from the registrar, right?
Then - turn off the cloud on the camera, it eats like crazy. leave access to a static IP
If they are nearby (local) - turn off the cloud on both devices. and upnp...
You can also cut the frame rate to 12k / s to save money.
If possible, go to unlimited, like an iota)

Answer 4

fps is 1/4
At the resolution of the main. flow 704x576
As for the cloud - off.

Answer 5

Show the firewall rules, maybe you have left traffic through the microt and walks. I had this happen to one of my clients...
