Many security applications are on the lookout for a complete surveillance system that they can install with minimal hassle and without having to first confer with a loan officer. A few good examples that come to mind include convenience stores, small retail shops and homeowners. Lorex specifically targeted those types of applications when they designed the L20WD804321 surveillance kit. This is most apparent in the way they incorporated the DVR into the monitor. This unique configuration not only saves you desktop space, it also means you'll have centralized, front panel control for both DVR and monitor functions.
You'll also benefit from the fact that all 4 cameras are designed to be both weather resistant and IR capable. This way, you'll get to install them indoors or outdoors as well as in areas with limited amounts of light.
Should you require broadening your CCTV coverage, you can purchase 4 additional cameras, of any type, and use your existing 8-channel system to manage the viewing and recording of all 8 cameras.
