Foscam cameras are GREAT products, in particular these model FI8905W for long distance observation and models ..04W and ..03W for "average distance" monitoring --- IF you purchase them from the right seller (more below). Get the model FI8905W with the 6mm lens for better coverage, this is the standard version. The 12mm lens is an option, according to Foscam's official web site. I also use FOSCAM outdoor models FI8904W (with 3.6mm) lens and FI8903W (with 3.6mm lens), and indoor model FI8918W (PTZ). If you are setting up a whole-house system consider Blue-Iris (full version) software for MS-Windows, or Zoneminder for Linux. Both work great with these cameras. Also great Android apps are available to control the whole system from your phone or Android Tablet.
CAVEAT choose your seller CAREFULLY (the seller shown above is probably not the one I purchased from, because Amazon rotates sellers per product availability.) Because these cameras are popular, there are clones that look identical but they do not have the functionality when you go to use them. Also, Genuine FOSCAM camera Models FI8903W, FI8904W, and FI8905W are currently manufactured in a "NEW" hardware design that supports encrypted Gmail alerts (smtp TLS/STARTTLS - also called SSL encryption). In three of my purchases from one seller, I received the old hardware, labelled as NEW. This hardware arrived with OUTDATED firmware and outdated Web-UI which I was advised to update. However, email alerts still failed giving the error "This device not support TLS/STARTTLS". NEW FIRMWARE IN THE OLDER HARDWARE WILL NOT SUPPORT TLS/STARTTLS EMAIL ALERTS. I had to return three of four orders from one Amazon seller due to this problem. These were orders fulfilled by Amazon. I AM THANKFUL FOR AMAZON'S GREAT RETURNS POLICY AND EXCELLENT CUSTOMER SERVICE WHICH ALLOWED ME TO RETURN THESE DEFECTIVE ITEMS SO EASILY.
I reordered more FOSCAM's from Amazon, this time from two different sellers. They arrived with Current hardware, Current Firmware and current Web-user interface already loaded, and these Foscam cameras worked PERFECTLY. This poor review reflects upon the first seller I chose, not the product. Check my other reviews of Foscam. I give FOSCAMs Five Stars. If you don't need encrypted email alerts, the old hardware from any seller will probably work fine for you.
