The EverFocus 4-Camera and 4-Channel DVR Indoor Dome Kit from B&H is a low-cost solution for residential and commercial security applications.
The four cameras of the kit are color cameras and they capture video at 380 lines of resolution, which is supplemented in the cameras by a host of controls that maintain image quality in low-light conditions. The cameras' lenses are zoomable from 3.8 - 9.5mm for near or distant viewing, and the zoom is manually adjustable.
The DVR has four channels and can record from all four cameras at the same time. It records in H.264 format and saves to 500GB of internal storage space, which is enough to support the footage from all four cameras. An important feature the DVR offers is Pentaplex Operation, by which per a connection to a display screen you can view live footage while simultaneously recording it, and you can as well view recorded footage while continuing to additionally record.
The kit is complete with four power cables and four power adapters and comes to you at a discount over the total cost of its individual items sold separately.
