With more benefits than we can mention, the MobiCam DXR has won numerous national awards and high praise. Impressive optics include a high-resolution quad monitor screen, wide camera viewing angle and infrared night vision up to 40 feet. The Communication module features voice-activation and 2-way talk-back to keep families in contact. DXR is expandable up to 4 cameras* with simultaneous viewing. Plus you can record to an SD card via the built-in SD card slot. Each video file from the Digital DXR is recorded with a date-and-time stamp in standard AVI format. It can be easily played and scrolled through like a DVR recording, letting you review what you may have missed throughout the day. You can review footage using either your PC or the MobiCam monitor, and then decide whether to archive or share your recordings on YouTube, Facebook, or via email.
