Oops! Wrong one. This has the same bandwidth, but is rated for only 2 cameras: http://www.qnap.com/pro_detail_feature.asp?p_id=161 That's a good suggestion Matt. I'll call Qnap on Monday.

Thanks for the info Matt. This Qnap network storage unit has over 100mbps bandwidth, yet the data sheet specs it for only 2 IP cameras: http://www.qnap.com/pro_detail_feature.asp?p_id=162 I don't get it.

Hi, I know very little about the workings of a network and I'm having trouble understanding a few things. I have a few questions: Network NVRs seem to be considerably more expensive than Network Storage units. They seem to be similar devices but there must be a reason for the price difference. What am I missing? Also, why do network NVRs have a specific channel number? It seems like you should be able to have as many cameras as the bandwidth permits. Thanks

I just read this. Arecont rates this lens to be good up to 5MP: http://www.arecontvision.com/uploads/product_images/0MPL_Vari_Focal_Lensespdf.pdf

I bought 2 of the Rainbow 4.5-10 lenses you mentioned for use with 2MP Arecont cameras. I later ended up with an Arecont 3MP dome camera. To my surprise, it came with a lens identical to my Rainbow lens. As best I can tell by looking at photos, the Arecont 5MP dome cameras also come with this lens. Arecont also sells this lens: http://www.arecontvision.com/index.php?section=product&subsection=product_details&product_id=49 So either Rainbow is under-rating this lens, or Arecont is including an insufficient lens with it's 3MP and 5MP dome cameras.
