A solid performing industrial grade real time digital video recorder for a great price. Protect your home, office, and business with the Clover 16 channel video security DVR. The installed 500 GB HDD can store recorded events for an extended period depending on the record settings. Receive hard disk drive email status alerts with the installed SMART utility (Self Monitoring Analysis and Reporting Technology). The sixteen video inputs are all BNC connectors that make this unit a perfect choice for any new or replacement application. The Industrial Grade DVR has default settings that allow a simple plug and play operation but is fully programmable and can be customized to your requirements. Recording Set Up - program the image size, frames per second, select from five quality levels, pre-alarm and post-alarm time; Recording Modes - Continuous, Scheduled Recording, Alarm Sensor (the system will begin recording when an alarm is triggered but an external alarm sensor is required for this feature), and Video Motion Detection (this setting breaks the screen into a 15 x 15 Inches grid with five levels of sensitivity and allows you to decide what areas of the screen, or all of the screen, will trigger the system to record once it detects motion). Both the Alarm Sensor and Video Motion Detection settings can be customized as well. These advanced settings will not only save hard drive space, but also time spent viewing recordings. Reviewing recorded video is a breeze. With just a few clicks, the Quick Play selection will play the previous 10 minutes of recorded video. Recorded video can also be accessed using the calendar search and event search. Easily back-up recordings using a USB, external hard drive, stick memory, or through the network. Everything needed to install and use the Clover security system is included in one convenient package. The system is very easy to install and set up but if help is needed just call our friendly technicians and they will be glad to help.
