The HikConnect smart phone app can alert users to event triggers such as Line Crossing Detection, Intrusion Detection and Motion Detection. We recommend powering the DS-2CD2146G2-I by PoE, however it can be powered by 12V DC power supply unit (not included) Smart Event Line crossing detection, intrusion detection, region entrance detection, region exiting detection (support alarm triggered by specified target types (human and vehicle)), scene change detectionFor seeing as much of the immediate area as possible such as above a doorway/low down/garage soffits (edges can appear slightly warped/distorted) - clearly "zoomed out"

AcuSense technology uses deep learning algorithms to focus on human or vehicle targeted alarms. The technology has been proven to greatly reduce the occurrence of false alarms that were previously triggered by subjects other than humans or vehicles, such as wildlife, rain, or falling leaves.The Hikvision DS-2CD2146G2-ISU is one of the latest 4 megapixel dome cameras within the new G2, AcuSense release for 2020. Included is a built-in microphone which can record sounds up to 5m away (depending on environment). A great general purpose option giving great coverage still in the corner of a room or higher up on second floor soffits with less distortion - more of a natural "zoom" EMC FCC (47 CFR Part 15, Subpart B); CE-EMC (EN 55032: 2015, EN 61000-3-2: 2014, EN 61000-3-3: 2013, EN 50130-4: 2011 +A1: 2014); RCM (AS/NZS CISPR 32: 2015); KC (KN 32: 2015, KN 35: 2015)

With a rating of IP66 confirming this dome camera is weather proof and suitable for use externally, the IK10 rating also means the camera is vandal resistant making it a great choice for public spaces.
