"I bought one of these a few weeks ago on Ebay and for the price I'm really satisfied with it.\n\nHikvision DS-2DE4A320IW-DE 3MP Network IR PTZ Camera, 20× Optical, 16× Digital | eBay \n\nI see how popular the Dahua PTZ with auto-tracking is here, but I wanted a cheap Hikvision PTZ since I use a Hikvision NVR (for now, BI seems to be inevitable). Thanks to you guys, I understand that the 3MP resolution 1/2.8\" sensor size combination is not ideal, but I use it in an area with a floodlight, so it still works well at night.\n\nThe camera came sealed with firmware V5.5.71 build 180725 loaded. The serial number label on the box had a little label I peeled back to reveal the original firmware was V5.4.8 build 170210. In any case, I loaded the latest (and probably last) R7 series firmware V5.6.18 build 210622 with no problems. That didn't add or remove any features or change anything as far as I could tell... I did need to upgrade the firmware for medical reasons (OCD) and more importantly shits and giggles. I'm assuming it's a US region camera as it has the UL listed logo.\n\n\n\nOf course, I'm getting mixed results with the auto tracking, but I'll keep experimenting.\n\nThe eBay listing shows 30 sold and 43 watching and the seller has good feedback. In short, the camera seems like a good deal for someone who wants a Hikvision brand PTZ to experiment with."
