Hi,pfred,thank you for your attention on my information. "double encoding" can support two encoding stream, one is used to disk storage and the other for network transmission, which can reduce the request on network brandwidth. we use TI chip, and H.264 compression technology Grace

hi,i suggest you adopt the 4 channel pc-dvr,and you can add the professional dvr motherboard,which is more cheaper than standalone 4 channel DVR. the cost performance is wonderful. Grace feng

Hi,i think the importantant feature of DVR is just like you said:resolution,recording speed,network function, reliability. But i would like to supply another points:real-time video and audio compression,support maximum 64 channels ,support motion detection,support double encoding.
