The Clover Industrial Grade 4 Channel Video Security System is a fantastic choice for any small business or home installation. The package is complete with indoor/outdoor night vision cameras and all the accessories needed to easily install and operate the system. With all the programmable features including remote access with most smart phones, recording modes, play back, view settings, email notifications, motion detection, and more, the system will provide years of reliable service. Keeping an eye on your home or business has never been easier. Access the DVR remotely to view live video, play back, configure the settings, and even back up the data on a PC and with most smart phones. The DVR can be set to record continuously, on a programmed schedule, or during alarm events. The installed 500GB Hard Disk Drive provides for extended recording time so nothing will be missed (subject to record settings). To maximize the disk space, the system employs the latest H.264 video compression method. The night vision 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. Each camera can be viewed individually, view four at one time, or the camera view can be set to sequence. Unlike most system cameras, the OC155 terminates with a BNC connector instead of a proprietary 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. Whether used for the office, warehouse, retail store, or even your home, you can trust the Clover PAC0420 Industrial Security System for continuous protection.
