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). For 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"

As a rule of thumb, we recommend 2 Terabytes for a 4 x 4/5MP HD camera setup, as this should give you approx 2 weeks using H.265 @ 20fps and that is on continuous, not motion-detected recording. You can also use the Hikvision online calculator to work out what works best for you specifically: https://tools.hikvision.com/ca... 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: Protocols TCP/IP, ICMP, HTTP, HTTPS, FTP, DHCP, DNS, DDNS, RTP, RTSP, RTCP, NTP, UPnP™, SMTP, IGMP, 802.1X, QoS, IPv6, Bonjour, IPv4, UDP, SSL/TLS

A new 3D dynamic noise reduction (DNR) algorithm helps the cameras record additional remote details clearly and deliver sharper images. In addition, cameras with ColorVu technology are equipped with a soft and warm supplemental light that illuminates to guarantee color imaging even in zero-light environments. 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" The newly released cameras with ColorVu technology offer enriched options to the market in both Turbo HD and Network products. The enriched ColorVu series can satisfy a multitude of customer needs, from high performance products to budget friendly choices and smart solutions.

The newly released ColorVu technology lenses have kept the F1.0 super-aperture design, allowing four times more light to enter the lens than conventional cameras (that have F2.0). Focusing high definition cameras with large F1.0 apertures is technically exceptional for the industry, requiring very strict and accurate manufacturing. Hikvision has applied its advanced Active Alignment (AA) Technology in the production of ColorVu to bring the adjustment accuracy to within 4 pixels, even smaller than 1/30 hair diameter.
