Hello there, I'm looking to get a PTZ camera so that I can identify faces and number plates when they arrive at the front gate of my property. The front gate is approximately 50m away from the house and acts as the entrance to a driveway. The PTZ camera will be mounted at the house facing the driveway. I already have a few Hikvision and Hiwatch IP cameras. I'm very pleased with the quality with these cameras, however I need to be able to Zoom up close. For this reason, I doubt a 4X camera will be good enough so I'm looking at 20X optical cameras. It must support POE and RTSP. Some kind of AI and patrol function would be a nice bonus. So far I have found the following: SUNBA 3MP IP PoE+ PTZ Camera Outdoor, 20x Optical Zoom@H.265, Motion & Human-Shape Detection, 24x7 Automatic Patrol, up to 100m Night Vision and ONVIF (405-D20X ECO Edition) There are also some cheap ones on Ebay for about 110GBP. What does everyone recommend without spending too much money?
