This is the wireless video monitor system that delivered the longest range, the clearest images, and offered the most convenient features in testing by The Hammacher Schlemmer Institute. The camera's 2.4 GHz wireless signal reached an unobstructed monitor 550' away--more than twice as far as lesser models with a 250' range. Unlike other monitors that lost video and audio quality when positioned further away from a subject, The Best Monitor consistently displayed crisp 320 x 240 pixel images on a 3 1/2" color TFT display (and black and white night vision) without interference from other household electronics. The only monitor that allows remote viewing from an iPhone or iPad via Skype, The Best Monitor also functions as a wireless intercom, and displays the room temperature. It can automatically record video onto a microSD card up to 32 GB (1 GB card included) allowing footage to be viewed on the monitor or downloaded to a computer. Camera plugs into AC; monitor has a rechargeable battery for up to four hours of untethered use from a six-hour charge in its AC charging dock. Monitor 3" H x 5" W x 1" D. (5 oz.) Camera 6" H x 3 1/2" W x 2 3/4" D. (6 oz.)
