If you are using Cisco switches and they are older, meaning 3550's they only support Pre-standard cisco POE, and your cameras will not work with those switches. if they are switches which support 803.1af you will be OK

I have a 2811 router that is running my ip voice phones, the cameras are connected to a 3750 switch...........all is working well now....thanks

I am using a Cisco router as my NTP server, I have all the camera's and the NVR pointed toward this router. All the camera's have DST set. this is the only way I got things to work correctly

Did some more testing, and bp2008 you are correct if you are pointing the camera's at a specific NTP server set DST on each camera, but if you are pointing the cameras to the NVR, and it is set with DST, you do not set it again on the cameras. i have pointed both the NVR and camera's to a...

I played around a bit. The NTP server should be set with DST, and the severs clients only need the timezone configured. Since I am using the NVR as the NTP server, I configured DST there, and not on the Camera's.

Just would like to get some info on setting up NTP on the NVR and the camera's connected to the system. I do not have a NTP server on my network, and do not have so I was wanting to use the NVR as the server. I have tried to confirure the camera's to use the NVR as their NTP server, and with...

I purchased a dahua 16 channel NVR, but it seems when I place a 9th camera on the system, it doesn't work. Under system info it tells me it is a 16 channel record, I can also display up to 16 camera, but think that doesn't mean anything I only have 9 camera, and waiting for delivery of my...

I have 2 0f them in the same lighting conditions, and one looks good, the other is black. on the K100W how do I turn on the light?

I am new to this and am not sure if I am missing something with the config, or the camera's are just not working like I expect. I purchased a few DH-IPC-HDB4300C's and one of them, it seems that the IR functionality does not seem to be working. 3 of them go to B&W when the room goes dark, the...

Been Playing with my new Dahua NVR and cameras, and have a question. I have gone into my camera and changed the admin passwords so they are secure, however now I am getting a "Invalid password" message on the screen. How do I change the password the NVR uses to access all the cameras. I do...

There are other extensions I would like to know about. Thanks

wHAT ABOUT IPC-HDB4300CE?

What is the difference between ipc-hdb4300c, cn, cp?i have downloaded the data sheets and can't see any difference. Can someone enlighten me

no I am looking after an 93 old mother with dementia, which has made me crazy, and I can't read anymore

33%n of 100 is 33Mb and you say you can get to 12.5, that is average. Cheers,

the conversion between gig and 100MB Ethernet requires memory buffers and cpu cycles to disassemble and assemble the different packet structures. 100Mb Ethernet crashes at 33% or about 32.5Mbps once there is more data than that on the wire it will crash. The most any 100 Mb camera can send to...

Even though the Gigait Ethernet is faster, there are no Gigabit cameras as far as I know, they are all 100Mb. the only way to converge these streams into a Gigabit signal is to go through a router which will have to process this signal.

I have just started down this road and I am not an expert by any means, however if you were to look at an NVR internally it is a router, a PC which processes then video signals and a switch, or switch port which connects to the switch where cameras are connected. 100Mbit Ethernet does not give...

the 4216 is too small, I would like to get the 4416, i will purchase it from Ali, thanks guys you were a big help

Would any of you buy from: Alibaba? CCTV-Mall China?

The 4XXX series is ONVIF 2.3 compliant and the 5XXX is 2.0 compliant. That's why the 4XXX supports more camera's it has newer firmware

the reason I started down this road, in the last month I have caught 2 punks putting graffiti on my parents place one was arrested, my dad had a heart attack earlier because of graffiti notice because in our city has a stupid bylaw that says the owner of the property is responsible to clean up...

I just read this, and looked up the 4XXX series I think I am missing something here. Above you compared then 4416 to the 5216. What if you compare the 4216 to the 5216? or the 4416 to the 5416? I choose the 44XX because I am looking for more storage, actually was looking at the 48XX because...

I read somewhere here that the NVR4XXX is newer than the NVR5XXX, is it not in ordermeaning that NVR3XXX is older than NVR4XXX and then NVR 5XXX?

What suppliers would you suggest in Canada for dahua NVR's? Searching the web i have found the NVR5416 without a internal POE switch, but no one seems to carry it. I have found a supplier for the NVR5816, but I believe this is overkill
