About this deal

Power Supply 12 VDC ± 25% *You are recommended to use one power adapter to supply the power for one camera. 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. Hikvision's revolutionary Turbo HD technology brings with it a huge breakthrough in the evolution of analogue transmissions, opening up a whole new range of possibilities using coaxial cabling. The Turbo HD product family includes a comprehensive range of full high definition cameras and DVRs. See in the dark up to 60m with the cameras powerful EXIR night vision. EXIR will provide a more efficient and powerful night vision illumination (up to 30% more effective than tradition IR night vision). EXIR technology allows uniform IR illumination which eliminates traditional issues such as over exposure in the centre of the image and dark areas in the corner of the image. Frame Rate TVI: [email protected], 8MP@15fps, 5MP@20fps, 4MP@25fps, 4MP@30fps, 1080P@25fps, 1080P@30fps AHD: [email protected], 8MP@15fps CVI: [email protected], 8MP@15fps CVBS: P/N

Hikvisions up the coax technology gives simple access to the cameras On-Screen-Display (OSD) & built-in software, allowing customisation of the camera settings including colour, brightness & wide dynamic range for the best video quality every time. The weatherproof DS-2CE78U1T-IT3F-2.8MM can be mounted indoors and outdoors and is built tough enough to withstand whatever the weather throws at it. You can also use the Hikvision online calculator to work out what works best for you specifically: https://tools.hikvision.com/ca... Focal Length & FOV Horizontal FOV: 102.2° (2.8 mm), 79° (3.6 mm), 50.8° (6 mm), 37.73° (8 mm), 23.96° (12 mm)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"

The powerful fixed 2.8mm wide lens allows a large field of view, giving a huge coverage without the need for additional cameras. 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: 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). You may only require the full 25 frames per second on certain cameras if things are fast-moving - ie above a till)Narrows down the angle and zooms in to look past the immediate area a little to gain more detail - down a driveway for example from higher up 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"
