The Hikvision DS-2CD8464F-EIW takes the ease and simplicity of what you would want in a consumer grade camera and combines it with all of the power and features of a professional commercial grade security camera. Built in PIR motion detector for true motion detection recording which greatly reduces false recordings. 2 Large Array IR LED's gives this camera superb night vision in complete pitch black darkness. Built in Mic and Speaker for crystal clear audio in which you can listen in and speak to someone at the camera location with your cell phone or PC, all while watching them! No need to use a seperate recorder as this has a built in Micro SD card slot which turns this into a recorder as well. However, if you do want to use a seperate NVR recorder, this camera comes with complete Onvif conformance to work with many different brands of NVR's and recording softwares. Tons of features packed into one great camera!
