This is a 50 Ohm resistor connected in series with a diode and connected instead of a tube, for example:


●       0.25 W, 51 Ohm, Carbon resistor, Taiwan (chipdip.ru)
●       1N4001, Rectifier diode 1A 50V [DO-41] (chipdip.ru)
(Any analogues will do)

The GND terminal is located in the bottom row of contacts, next to the controller's external power terminal

81.30.195.190
10.2.88.9/32
77.79.161.0/24
81.30.199.0/24
94.41.0.10/32
94.41.80.8/32
81.30.201.150/32
136.169.226.0/24

The controller:
●       Internet access
●       issued IP address via DHCP
should be available:
●       sbc3.ufanet.ru port 5401
●       mqtt.ufanet.ru port 1883/tcp
●       dom.ufanet.ru via https
minimum speed is 128\128 Kbps

The camera:
●       RTSP stream with a white IP address.
●       RTSP stream with a gray IP address in case of installing a controller version 4.0 and higher + Beward (crazy box)
●       minimum speed - 3 MB/s (for one camera)

Check that the LN IN and LN OUT terminals are connected correctly, they may be reversed

Check how many cameras are connected to the router, and what is the Internet tariff (the camera needs 2-3 Mbit/s).
Check the camera settings: in the “Video” section, the “Video encoding” item should be H.264.
Check the cable line connection to the camera.
Check if the camera requires a system update.
Try replacing the camera's POE power supply.
Check the camera's connection to the Internet. There may be packet loss when transmitting them to the video surveillance server.

Check that the intercom model is indicated correctly in the provider’s account

1.  The camera receives an IP address from the router.
2.  The camera sends a request to the camagent.ufanet.ru server (94.41.0.10) on port 80 in order to find out which server it needs to connect to.
3.  After receiving the necessary information (domain name or server address), the camera tries to raise a vpn tunnel to the server vts0.avucams.com (vts1.avucams.com – backup server) on port 5000. Respectively, the Source IP address will be the IP address of the WAN interface of the client’s router . (100.33.44.55 in the example).
4.  At the same time, the server camagent.ufanet.ru (94.41.0.10), via port 80, sends a request to the server vts0.avucams.com (vts1.avucams.com) and adds a camera to the server config.
5.  The server vts0.avucams.com (vts1.avucams.com) looks at the received config and allows the creation of a tunnel from the camera on port 5000.
6.  Flussonic, on which the camera is installed, takes the stream through vts0.avucams.com (vts1.avucams.com). There is static routing between the servers vts0.avucams.ru, vts4.avucams.com and flussonnic servers, and it works in a separate VRF)

Accordingly, there should be no restrictions on port 5000 on your access network from the camera to the Internet.

1.  The camera receives an IP address from the router.
2.  The camera sends a request to our server camagent.ufanet.ru on port 80 (94.41.0.10), in order to find out which server it needs to connect to.
3.  After receiving the necessary information (domain name or address of your server), the camera tries to raise a vpn tunnel to your server on port 5000, respectively, the Source IP address will be the IP address of the WAN interface of your client’s router. (100.33.44.55 in the example).
4.  At the same time, our server camagent.ufanet.ru (94.41.0.10), via port 80, sends a request to your Flussonic server with our application deployed in advance, and adds a camera to your server’s config.
5.  Your server looks at the received config and allows the tunnel to be opened from the camera on port 5000.
6.  The camera inside the tunnel transmits the stream via RTSP.

Works with 4030 and 2028 cameras with special firmware. The cameras are configured themselves; the password on the camera must be the factory password: admin12345

Accordingly, there should be no restrictions on port 5000 on the access network from the camera to the Flussonic server. There should also be an allowing rule on the server for access via port 5000 from the IP addresses of your clients where you want to install cameras.

Check that the controller is connected to power and has Internet access. Connect your computer/laptop with the same wire and check the availability of Ufanet services:
●       dom.ufanet.ru
●       sbc3.ufanet.ru
●       mqtt.ufanet.ru

Depends on the intercom, it is around 120-160 Ohm

It should not be. There is direct current there.

Yes, you can use a separate 5...7.5V power supply, or use Boxer 3.4+ version. It has an output voltage of 6.3V

Boxer up to 5W, Domovoy RS485 up to 2W, Domovoy 2.3-4.0 up to 15W

The minimum voltage for powering RS485 v1.2 is 4.5V; RS485 v1.5 - 6V. The voltage on the Ln, Lu, Ek and Sel terminals depends on the intercom model.
For intercoms with 12V logic (Visit, Cyfral) on information buses must be at least 9V.
For intercoms with 5V logic (Eltis, Metakom) on information buses must be at least 4V.

This is a new feature. Previously, in RTSP, sound was recorded only from the Beward microphone (which happens near the entrance), now, if you check this box, the second track will be a stream from SIP (during a call to which a resident answers from the apartment).

125 kHz
