Dropcam is back with its second and most advanced security camera. Introduced back at CES 2012, the Dropcam HD is finally ready to ship and delivered within 5-7 business days. It’s quite a good bargin, too. Not much has changed since we first looked at the unit in early January. This model does 30 fps, night vision, two-way audio and 16x the resolution as the original Dropcam Echo. The live video is accessible for free through a cloud service and where for $9.99 a month Dropcam also offers a DVR functionality. At $149 it’s priced very aggressively against other products with a smaller feature set.
