Dahua's cameras are in loop > login and logout from a NVR

[lukiszyszka 0]

Hi,

I have a problem in one localisation.

 

There are 10 cameras outside. As NVR is Dahua 4116H device.

8 cameras are connected by POE switch, 2 cameras has own power supply and they are directly plugged into switch. 2 cameras, POE switch and NVR are connected to 1 Gb Asus branded switch.

 

From the first days in cameras are these lines in log:

It seems that a NVR (192.168.1.109) is still login and logout from each of camera. After few days working each of camera is hanged and must be disconnected. After powering again a NVR is connecting to the camera and all is working fine by next few days.

What I done?.

- changed an admin password to default "admin"

- changed Motion detection (which works very good) to Continous recording

- checked wires to cameras

- changed POE switch

- changed one 8 POE ports switch to 2x 4POE ports switch

- removed Internet from this network

- checked DHCP settings and range in TP Link router

- replaced switch in this network to Asus 1 Gb 5 ports.

 

When camera is hanged up, I can't login by WWW, sometimes I can login by Telnet.

 

I have few this NVR 4116H in other localisations and there is no problem.

 

What I will do:

- I will replace power supply to a NVR

- I will try to replace an NVR to other one

- I will connect an UPS device

 

On Dahua's site I have found:

message: I have two cameras IPC-HDW4200S (firmware 2.420) and a NVR NVR 4104P (Poe) (firmware 3.2300.VT00.0.R). Cameras are connected both to the NVR integrated poe switch. After some days (5-7) both the cameras lose the connection. In the NVR log i can read the messages "REMOTE INFO" and the cameras starts to LOGIN and LOGOUT. Any suggestion ? Could be a firmware problem ? After a software reboot of the NVR the cameras start to work properly... Thanks

Reply: Solution 1: Check if the network environment is good and the network cable hole plug of IPC end is loose. Solution 2: Check if there is IP conflict. Solution 3: Check if the device is under normal power supply. Solution 4: Check if the device upgraded to a wrong program.

 

A NVR is an English menu. Cameras?. Probably too, but I don't know. But are with an English language. But the same cameras are working correctly in other places from September, 2014.
