We're using this to monitor our showroom entrance since we don't have a person out there full time. We wanted it as a live view, so don't have it connected to a DVR. Some of my employees initially set it up, but said that the browser view requires a plugin and it wasn't compatible with many of the free software options out there (or maybe it is, but they don't list this brand.) Not that we're opposed to paying for software, but would like to demo it first. One we eventually found is called Sighthound Video and it seems good so far. There is only a 1 second lag. The image is high resolution and sharp except when something is moving when it has a slight motion blur. While I don't need it at night, I still had the software up and noticed that the image in the dark is incredible, grayscale, but otherwise nearly as complete as the daytime image. Since I wasn't using a DVR, I looked at power over ethernet switches, but ultimately got this�ONWOTE DC 12V 1A Security Camera Power Supply�since it was for indoor use and near an outlet. I did confirm with the seller as the specs list it as requiring very high voltage, but that's only for PoE, not a direct power supply. I believe that's because ethernet wires are very small and it requires high voltage to get enough current through them.
