I've got a US version Hikvision DS-2CD2032-I (it has a US UL sticker on it and no CH in the serial). It's currently on firmware version 5.1.6 build 140612. When I try to upgrade to 5.2 it says upgrading failed. I've updated the firmware once, I don't remember where I got the firmware from. Any idea why I can't upgrade it to any version? Thanks!

We've moved into a new warehouse and we want to install about 50 cameras. I don't think I want to deal with the infrastructure of HD IP cameras so I plan on installing non HD cameras. We've purchased DVRs in the past and they were pretty bad quality...bad interface...only work in IE on Windows XP, etc. Any suggestions on cameras and a DVR that is good quality (it would be nice if they had current apps that would work on an iPhone as well)? I'm assuming the cable will be coax with BNC connectors and a red/white wire to power the camera? Thanks in advance!

Thanks for the replies. Looks like that Hikvision NVR has dual gigabit interfaces so I can keep camera traffic on it's own network and interface with our existing internal network on the other NIC. I'll just have to add some POE switches. I've got some Hikvision IP cameras at my house and I like them so I'll probably just go that route. What are the typical focal lengths of cameras? What are the benefits or bullet and turret cameras?

Go with an ip system...that way if you are every unhappy with the interface you can move to a different NVR that supports that camera or a pc based system..you can start with a pc based system from exacq or milestone if you wish or just get a 64 channel nvr...http://www.hikvision.com/en/us/Products_show.asp?id=7701 It will be much easier to wire up an ip system as you dont have to home run all the cameras back to the NVR as you would with traditional coax. if you refuse to, then look at hdcvi which will allow hd over coax..if you buy a regular analog system you will again be unhappy with the poor video quality.. This warehouse is an offsite warehouse connected to our main office via site to site VPN and we just don't have the ports available to support IP cameras. The HDCVI format looks interesting. What are some good DVR's that support HDCVI? What is the best place to shop for HDCVI equipment? Thanks!
