    FPS vs. IPS

    Here is what I have gotten from our Engineer, if you are ready for the details: A sensor scans an picture in lines, it scans 240 lines (NTSC) to form an image. then 1 IPS=1 F(frame)PS=1 F(Field)PS=1 PPS Now if the picture is large and requires more than 240 line, the sensor scan the first set of 240 lines (the odd field), then scans the other set (even field) and combines the sets of lines (or fields) to form an image. In this case, 1 IPS=1 F(frame)PS=2 F(Field)PS=1 PPS. VCR Inc. always use frame per second in the specs. I am quite shocked that Field Per Second are being used in some other product specs. This marketing strategy does confuse the market and leads to unfair comparisions by the consumers. One suggestion: if the resolution on the spec is claimed to be 360 x 240, there is no need for further question because it takes 240 lines for an image anyway. If the specs claiming video reolutions of 680x480 or more, please do ask more questions regarding FPS. Confused? yet more to follow: I also have come across some claims regarding the resolution that has no relation to the actual image, but rather the display resolution of the monitor.

    FPS vs. IPS

    IPS (Image per second) and PPS (picture per second) are just common terms used by the general. FPS (frame per second) is a more precise and professional term. There is odd and even field together to make a frame. When the frame size is small, there is no difference between FPS and IPS because one field can form an image. FPS is less used as field per second, only if the frame size is small enough. Yes, one still can say there is no difference among all these terms, only if the frame size is small.

    DVR cards on Ebay

    Sometimes, you can find these knock off cards from those who has a physical store and on-line store. Recently I have been offered a list of these cards at dirt cheap prices from a so-called "distributor". On the price list, there is a physical address and a web site. I recognized some of these cards and contacted the original manufacturer whom I know very well. I were told: this "distributor" is already taken to court and waiting for trial! Always buyer beware!

    Strange object

    It's a balloon with a string attached. It is illuminated by the headlights of a car that's showing up a few seconds later.
