lukiszyszka 0 Posted April 5, 2015 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: 5 admin 2015-04-05 18:40:35 Logout {"Address":"192.168.1.109"} 6 admin 2015-04-05 18:40:18 Login {"Address":"192.168.1.109"} 7 admin 2015-04-05 18:40:07 Logout {"Address":"192.168.1.109"} 8 admin 2015-04-05 18:39:51 Login {"Address":"192.168.1.109"} 9 admin 2015-04-05 18:23:59 Logout {"Address":"192.168.1.109"} 10 admin 2015-04-05 18:23:43 Login {"Address":"192.168.1.109"} 11 admin 2015-04-05 18:17:12 Logout {"Address":"192.168.1.109"} 12 admin 2015-04-05 18:16:56 Login {"Address":"192.168.1.109"} 13 admin 2015-04-05 18:14:53 Logout {"Address":"192.168.1.109"} 14 admin 2015-04-05 18:14:32 Login {"Address":"192.168.1.109"} 15 admin 2015-04-05 18:13:36 Logout {"Address":"192.168.1.109"} 16 admin 2015-04-05 18:13:20 Login {"Address":"192.168.1.109"} 17 admin 2015-04-05 18:07:29 Logout {"Address":"192.168.1.109"} 18 admin 2015-04-05 18:07:09 Login {"Address":"192.168.1.109"} 19 admin 2015-04-05 18:06:13 Logout {"Address":"192.168.1.109"} 20 admin 2015-04-05 18:05:53 Login {"Address":"192.168.1.109"} 21 admin 2015-04-05 18:02:45 Logout {"Address":"192.168.1.109"} 22 admin 2015-04-05 18:02:22 Login {"Address":"192.168.1.109"} 23 admin 2015-04-05 18:01:56 Logout {"Address":"192.168.1.109"} 24 admin 2015-04-05 18:01:39 Login {"Address":"192.168.1.109"} 25 admin 2015-04-05 18:01:09 Logout {"Address":"192.168.1.109"} 26 admin 2015-04-05 18:00:56 Login {"Address":"192.168.1.109"} 27 admin 2015-04-05 18:00:56 Logout {"Address":"192.168.1.109"} 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.

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 by :dahua Time:2015-01-27 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. Share this post Link to post Share on other sites
