Get a smarter home surveillance solution with the REVO Indoor/Outdoor 4-Channel Surveillance System. Capable of connecting to your smartphone or home computer (PC or Mac), these surveillance cameras are supplied with four 60' Quick Connect RJ12 cables. The built-in DVR comes equipped with a 500GB HDD, 10.5" display and multi angle desktop stand. Plus, it's VESA-compatible for quick wall mounting. Though the surveillance system is small, it still comes packed with REVO's exclusive, powerful, integrated systems. REVO EZLink networks your system to the Internet — this allows your DVR to automatically notify you with Push Notifications when any or all of the cameras detect motion. In addition, you can set your surveillance system to email you with a picture of the camera's view when motion is detected.
