After officially beginning the REDONDO TECHNOLOGY Security Division, the question regarding 720P vs 1080P for high def analog video over coax cameras has come up.  Which one is better?  Per the industry standards, the 720P is being phased out and the 1080P has a much higher pixel resolution, allowing for higher definition and clarity.  It can be difficult to see the difference on smaller screens, you can really tell on larger screens and on devices with image filter software.  Our technology sources are practically giving away the 720P analog cameras as of late 2018, another sign that type is being discontinued.
