HIKVISION DS-2CD2347G2-LU (2.8 mm) 4MP ColorVu IP Turret Camera 24/7 Coloured Imaging with Microphone

Product Information

The second model you linked is a G1 camera. That is an older discontinued model (it has ColorVu but does not have AcuSense). I would advise against that.

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) Lens Type & FOV 2.8 mm, horizontal FOV: 109°, vertical FOV: 55°, diagonal FOV: 138°; 4 mm, horizontal FOV: 94°, vertical FOV: 48°, diagonal FOV: 115°; 6 mm, horizontal FOV: 57°, vertical FOV: 31°, diagonal FOV: 67° Unless selecting a vari-focal camera (with an adjustable lens) It is important to select the correct camera lens option for where the camera is to be positioned. A smaller lens will give you a wider angle but will be “zoomed out more”, while a bigger lens will narrow the angle down and “zoom in more”. See below to give you some idea on angles of Megapixel HD Cameras: Lens in mm Basic Event Motion detection (human and vehicle targets classification), video tampering alarm, exception Protocols TCP/IP, ICMP, HTTP, HTTPS, FTP, DHCP, DNS, DDNS, RTP, RTSP, NTP, UPnP, SMTP, IGMP, 802.1X, QoS, IPv4, IPv6, UDP, Bonjour, SSL/TLS, PPPoE, SNMPStartup and Operating Conditions -30 °C to +60 °C (-22 °F to +140 °F), humidity 95% or less (non-condensing) Smart Event Line crossing detection, intrusion detection, object removal detection, unattended baggage detection, Face Detection

This Hikvision camera utilizes furthermore an impressive range of smart features including line crossing detection and intrusion detection with notifications that can trigger recordings or notify you via your smartphone or tablet.

The amount of hard drive space you require is dictated by how many cameras, as well as their resolution, frame rate settings, and whether you have H.265 encoding enabled or not to save space (We advise turning it on to double the capacity shown below with ease). Exposure Time: support 1/3, 1/6 in Monitoring mode; can only support a maximum exposure time of 1/12 in Smart Event mode. Finally, you can often make your storage space last a lot longer by enabling motion-detected recording rather than continuous, especially if there are long periods of no activity (to perhaps double or more these figures again).
