Protect your home, office, and business with the Clover 16 channel DVR video security system. A solid performing industrial grade video surveillance system for a great price. The system includes 8 cameras but is expandable to 16 cameras. The 16 video inputs are all BNC connectors that make this 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 15x15 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. The cameras integrate newer technology to capture quality images. Each camera has 24 Infrared LEDs that provide up to 45-Feet of night vision and uses a CDS sensor as a light sensor to turn on the Infrared LEDs in low light conditions. Unlike most system cameras, the OC155 terminates with a BNC connector and can be used in most video surveillance applications. The enclosure is made of ruggedized steel delivering years of service and the low profile camera mount allows for a more discreet installation. 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.
