The Reolink PC820AD4K01 is a powerful 4K surveillance camera with 8-megapixel resolution (3840 × 2160 pixels), designed for both indoor and outdoor use. With its Ultra HD resolution, it offers significantly clearer image quality than 1080p systems — 4 times more detailed than Full HD — enabling precise monitoring of details during live streaming and recording. The camera features intelligent person and vehicle detection, which reduces unwanted alarm triggers caused by movements such as falling leaves or flying insects through modern algorithms. This makes security more efficient and reliable. Another advantage is the full-color night vision with integrated spotlights, which automatically activate upon detecting an intruder to warn the perpetrator while simultaneously capturing the scene in color. The spotlights can also be triggered manually to proactively prevent incidents. The camera also supports time-lapse video recording, allowing time-intensive processes such as construction work or sunrises to be documented in a compressed format. Remote access is always possible and available anywhere via the free Reolink app for iOS, Android, Windows PC, and Mac, without any subscription fee. The intuitive interface enables quick setup and flexible control of camera functions.
