When a look up Hikvision, the price is about USD80. But in our country (from official seller) is price 2 times expensive. So is It original from Hikvision? http://www.aliexpress.com/store/product/Free-shipping-wholesale-Hikvision-DS-2CD2032-I-bullet-Camera-CCTV-camera-IP-camera-nimi-network-camera/1010031_1317354518.html Or It does not matter?

Which models of Hikvison and Foscams do You use?

Sorry, my mistake. I have read his message inattentively. So only way is It buy the camera, which some sellers guarantee functionality with mini NVR (I saw some when I search problem with motion detection).

On the NVR It might be possible (access via telnet), but HW is limited. Better solution could be Raspberry PI or buy camera which support audio. For example: http://www.ebay.com/itm/ABR-H-264-30M-IR-1080P-2MP-HD-IP-network-Camera-Waterproof-P2P-ONVIF-audio-I-O-/371242236627?pt=LH_DefaultDomain_0&hash=item566fc2fad3 (and buy external microphone or find another camera which will have it built-in)

I have not ever heard about it - only the IP cameras has built-in microphone. //Or You can user Raspberry PI to record audio which will be streamed over IP using RTSP

There is new firmware (working - no bricking): Small_mini_8ch_0153_3520d_A_web_nor_2015-01-24 Small_mini_4ch_0152_3515a_A_web_nor_2015-01-24 and other tools (boot recovery and so on) for mini NVR.
