Our installers report that about 80-90% of new installations are being wired with CAT-6e now. So, if you’re still running CAT-5e, start changing over immediately. This means you’ll have to order CAT-6e, and you’ll need to purchase new RJ-45 connectors for CAT-6e as well.
The problems we are running into with IP security cameras though, is that the resulting bandwidth and file sizes are huge. A 3 or 5 megapixel camera produces huge pictures that not only cover a wide area, but will allow “zooming in” multiple times without blurring and pixelating the picture. But since each captured image will result in large file sizes, the resulting bandwidth and storage will create problems.
