I use the Lorex badged one at my home, with the latest Hikvision firmware installed. https://www.lorextechnology.com/Security+camera+system+Wireless+camera+system/Security+NVR+with+IP+cameras/prod360017.p?skuId=LNR282C4B Which is a version of the HIkvision: http://overseas.hikvision.com/en/Products_accessries_212_i3171.html NVRs usually have two important specs, 1) max incoming data bandwidth and 2) max frames per second This 8 channel Hikvisions specs for this are: 1) 80 Mbps and 2) 240 fps. These have to be divided by the number of connected cameras. I set each camera to be 5 Mbps, some are 20 fps (dark areas) and some are 30 fps (well lit areas). This one can do 480 fps. https://www.lorextechnology.com/HD-IP-security-camera-system/IP-camera-system-with-16-channel-NVR-and-PoE-switch/LNR366.p This one is more capable, see the specs. http://overseas.hikvision.com/en/Products_accessries_210_i2106.html The NVR reads the stream from the camera, the main stream, at what ever speed/bit rate/resolution you have configured it to be. The NVR will use it as is, untouched. It buffers it, examines it and it needed, stores it. This is how Hikvision/Swann/Lorex/LTS/Q-See/AvertX all work. Over and out, the earth is not flat either.

As part of each Hikvision NVR's specs, it lists the max video throughput that each one is capable of processing. The NVRs are more capable than PC running BI at a much lower power usage. The hardware is designed for this one purpose. All video processing and motion detection happens on the NVR. The motion detection in each IP camera is not used. If you want to use the motion detection in each IP camera, you can, and direct the output to another storage device such as a NAS or NFS file share. I have also used their IP cameras with builtin uSD cards to store the motion video alarms internally in the similar way. This would give you two independent locations to store motion detections. I have done this, with two independently controlled motion zones, sensitivities, etc. The NVR records video based on other signals besides the motion control, it is buffering video all the time, so that it can store videos for motion detection, camera tampering, camera disconnects, etc. There are settings in the NVR for pre-alert recording, that is why the NVR continually records on all channels, so that it store pre-event video. I set one of my NVRs to record 5 seconds before any event and 5 seconds after. This is how it is.

Cameras do it. Incorrect. With a Hikvision NVR system with their IP cameras, the motion detection is performed in the NVR, NOT in the cameras. If you connect them on your LAN and not directly to the NVR's POE switch, you can use BOTH, but I'm guessing no one does that.

Good stuff. In the newer firmware of this model with the HIkvision firmware it is different yet again. A true test would be for you to power down the NVR, disconnect power, unplug the first HD's SATA cable, then power up with just the 2nd HD connected, verify the system boots up ok and continues to work. Then reconnect everything.

yep, that is it. A weird way to have this setting in their NVR, I think. Report back if it works ok.

There is an option for each camera to set too. Did you find that option?

I just played with using a name and not an IP address, it accepts it. So I take back what I said above, as I had never used the name before. Yep, as long as you expose/forward the remote address of the camera, you will be ok. You can configure the data bandwidth that will be taken up by each camera via the NVR config screens.

So your saying even the NVR will connect to a WAN camera (bandwidth permitting)? If the WAN camera has an IP address and is accessible, then there is no difference. It needs an IP address, it can not use a name.

Any camera with an IP address/port can be used, LAN/WAN all the same. The WAN bandwidth will be the only limitation and your ability to make sure all the addresses are accessible.

You have the option to use POE or the DC connection. It supports both.

If you want to be happy, get the same brand of camera that the NVR can use.

Should work well, make sure you update all the firmwares.

The foam needs to push right up against the dome. The inside needs to be cleaned with glass cleaner, make sure the silica gel is dry before closing it up.

Is that a dome camera or bullet?
