In this instance, I am referring to Lorex systems. Installed/commissioned a bunch of those lately. Yes, Tom they do digitally zoom(a bit). The point I may not have made clearly is: the "zoomed" image is worthless. The manufacturer even admits to this, yet they still keep selling these systems of MP cameras and NVR's that cant provided a usable image in "zoomed mode". Avigilon has solved it for Super Mega Pixel cameras, even in Remote viewing! Yes, they solved it and that's why they are far more expensive. But, it's not rocket science. Basically tom, I 'm just ranting, tired of the client coming to me a saying they can't zoom.
Please don't lecture me about cameras with motorized zooms or vari focus. I know all about it but that's not what the client wants - if a thief parks right in front of their shop window with a new 4MP camera pointed at it, in broad daylight. They expect to zoom in on that image recorded or not, and get a clean license plate when the car is only 25 feet away. But they can't. The police can, by extracting One frame and running through Photo Shop. Camera's aren't wrong, it's the software.
