Product Information

Both of the above variants are current models - the LSU/SL model is not a newer version of the LU. They're the same model but the LSU/SL has two way audio (microphone and speaker) and also the strobe light. So for your numbered queries: Protocols TCP/IP, ICMP, HTTP, HTTPS, FTP, DHCP, DNS, DDNS, RTP, RTSP, RTCP, PPPoE, NTP, UPnP™, SMTP, SNMP, IGMP, 802.1X, QoS, IPv6, UDP, Bonjour Audio Bit Rate 64 Kbps (G.711ulaw/G.711alaw)/16 Kbps (G.722.1)/16 Kbps (G.726)/32 to 192 Kbps (MP2L2)/8 to 320 Kbps (MP3)/16 to 64 Kbps (AAC-LC)

Smart Event Line crossing detection, intrusion detection, region entrance detection, region exiting detection These Hikvision cameras features PoE for easy connection and configuration, via Hikvision NVRs and also 120dB Wide Dynamic range as well as 3D Noise reduction.The DS-2C2347G2-LSU/SL now also draws from the same deep learning algorithm that is featured in AcuSense technology. This enables the camera to focus on human and vehicle classification and reduce the occurrence of false alarms. 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" You can also use the Hikvision online calculator to work out what works best for you specifically: https://tools.hikvision.com/ca...

I've done a search on this forum and discovered that unfortunately, after the feature was introduced, subsequent firmware updates added and removed this feature.
