This is a 720p Indoor Outdoor HD-CVI Vandal Resistant Dome Security Camera. You will be amazed at the clarity that this dome camera delivers. Imagine being able to zoom into your recordings and see more detail, with less distortion, than with older analog cameras. That's right! HD-CVI blows away analog and is very affordable. In fact, if you have an existing analog system and wanted to upgrade to HD without incurring the high price of re-wiring, you will be happy to know that HD-CVI works over standard coax cable. You can leave your cable and power in place and just replace your cameras and DVR.
