TheVigil DVR supports recording from
high-resolution network cameras. At right is an actual-size crop of an
image from the featured IQEye IQ-501 camera. To get this clarity with a
standard analog CCTV camera, you'd need a lens zoomed tightly on the
rear of the vehicle, able to see only a narrow area. A high-resolution
digital camera, transmitting over an IP network rather than analog
video cable, captures a broader area in higher detail, allowing one
camera to take the place of two, three, or more regular CCTV cameras. Click here to view the full-size 1.3MP image as captured by the IQ-501.
Shown
here is an analog paypoint camera recording at CIF resolution (352x240
pixels). Most analog DVRs and cameras max out at 4CIF (704x480) or D1
(720x480) resolution, because of limitations of the NTSC video signal -

The
IQEye series of high-resolution IP cameras can be installed in most
housings and locations where a standard CCTV camera would be installed.
Weatherproof, vandal-resistant domes are also available. Resolutions range from 1.3MP (1280x1024) to 5MP (2560x2048) with framerates up to 30fps.
