I have the DS-7616-NI-SE/P and it does not have any alarms. Furthermore, it loses network connection all the time (we're a network company ourselves so we know "kind of" what we are doing:). So we're about to take our loss on this one and go for another solution. Hikvision Dome IP cameras are fine, but I would not recommend their NVRs to anyone.

I am not using the POE since the estate is way too big to have direct NVR-to-camera cabling. Instead, I access the cameras over the LAN using 192.0.0.0/24 The POE ports are configured to use 192.168.254.1, 192.168.254.2 etc but as explained, I do not use them. I am now also looking at Synology's Surveillance Station, looks promising and more up to date than Hikvision's software. John

Xeoma also does support Linux. And of course there is open-source ZoneMinder. But I'd prefer to continue using the NVR. What I'll do is try to obtain a login to the Hikvision NVR (http://console-cowboys.blogspot.nl/2013/01/swann-song-dvr-insecurity.html or via other means), and I'll post my results here. Regards John

Update: my setup (now with 6 cameras -- will upgrade to 10 soon) has been working well in the 192.0.0.0/24 range for a few weeks now. I have not experimented with other ranges such as 192.168/16 or 172.16/16 or 10/8 yet apart from my initial attempts. However, the NVR is now losing connection about once daily. It has the ip address 192.0.0.39 which becomes unavailable for some reason. All Hikvision cameras in the same segment (e.g. 192.0.0.20) are still connected. Because there is no debugging/logging whatsoever and I cannot login using telnet or ssh, I will probably automatically reboot the nvr every night to prevent the NIC from locking up. Needless to say, I regret buying this Hikvision NVR and will not recommend it to my customers. Instead, I'll try to work out a solution based on stock Linux with one of the commercial software suites instead. At least on the network level, I have full control in such a setup.

I just solved it. It seems that my range (a perfectly valid /24 private range from 10.0.0.0/8) is *not* supported by Hikvision. When I used their (non-compliant:) 192.0.0.0/24 range, it all worked. John

Hi, I purchased seven Hikvision domes and one Hikvision NVR (7616 NI/SE-P) through Aliexpress. The domes work fine. However, the NVR does not connect on its LAN1 interface to the main LAN here (network 10.17.0.0/24) Whether I give it a fixed ip (10.17.0.39) or use DHCP, no connection is being made. So no ping, no web interface. I did not change anything to the 8 POE ports of the device which use 192.168.254.0/24. I use version 2.3.7 of the firmware. The problem is, as there is no (external) serial connector and no CLI terminal nor telnet, I'm pretty much in the dark and have to use the GUI interface which lets me set the IP address, but then still does not make a connection. Obviously, I tried several switches and network cables and the network itself is ok. The front-side Status LED remains dark but the TX/RX led lights up; also the switch LED lights up. If there any way around, any debugging mode or anything else I could try? If it does not work, my only other option would be to buy a separate server and install Xeoma. I hope someone can shine a light on my problem, thanks a lot! Regards, John
