I know a supplier where I have purchased Dahua at 4 Channel PoE NVR $155 without a hard drive IPC-HFW1200M $115 I don't know about Hikvision, but dahua's small nvr's dont allow recording at 3mp. Max is 2mp.

I just ordered one from amazon and found the image quality to be almost the same as the dahua 4200 series. Only at night there was a slight difference.

@Boogieman do you mind sharing the firmware update with us? I asked two different distributors in the US and they didn't have an update. This was 2 months ago. It would help tremendously to all the users here.

Joe it cannot be solved b firmware update. I tested that camera and the mic in it is very poor. Don't waste your time with that camera. Most sellers I know are no longer selling it for its audio capabilities.

It's better to spend a few extra bucks and help a company in your own country that will take responsibility.

15fps at 3mp only. 30fps is a misrepresentation. You can get 20fps from a 3mp ip camera camera by dahua. for example a company I recently bought from has it for $140 wholesale: http://www.cctvcameraworld.com/3-megapixel-ip-security-camera-bullet.html Just email them and register a business account. If you want 30fps, then wait later in the year. Dahua and Hikvision should be coming out with something better.

Are you buying Hikvision labeled cameras or oem? I ask because oem/white box hikvision are not supported by hikvision usa. Are you in the US?

Could you please tell me which image sensor it uses?

I don't like hikvision nvrs as much as I like dahua ones. Why are you not getting a Dahua NVR?

What about DWDR? is it gone in the 1200 series?

Has anyone used these 1200S Dahua cameras? http://www.amazon.com/gp/product/B00OAAI8OQ What's the difference from the 4200?

delay is approx 150ms-250ms with most axis products Can you clarify whether the stream is over http or rtsp?

The delay on dahua cameras using mjpeg or h264 is the same, or even worse in mjpeg mode when using rtsp. Can you confirm there is no delay with axis cameras? I guess they also have a http video stream?

The --rtsp-tcp in vlc and ?tcp in the url made no difference. How do I run this command? ffmpeg -rtsp_transport tcp -i "Your RTSP URL in between these double quotes" is it for linux or also possible to run it with the windows version?

Another thing, I heard that the Ambarella DSP vs TI DSP handle RTSP differently. A distributor in the US told me that the ambarella dsp offer three streams, where the third stream is geared for rtsp use in access control and other 3rd party systems. Those streams are optimized for realtime, may be they are tcp forced from the start.
