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 | Approx Viewing Angle (degrees) | Ideal Distance (metres) | Typical usage/notes |
|---|---|---|---|
| 2.8 | 106 | <6 | 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" |
| 3.6/4 | 83-90 | <12 | 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" |
| 6 | 56 | 6-20 | 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 |
| 12 | 24 | 20+ | Zooms in significantly more to look at a gate, entrance or adjascent building |
| 16 | 19 | 24+ | As above but more so |
The amount of hard drive space you require is dictated by how many cameras, as well as their resolution and frame rate settings. 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.

As a rule of thumb we recommend a minimum of 2 Terabytes per 4 x 2-4MP HD cameras, as this should give you 2 weeks to a month with a few adjustments on motion detected recording. You may only require the full 25 frames per second on certain cameras if things are fast moving.

Hikvisions DarkFighter technology enable these cameras to stay in colour mode for longer than some of their other counterparts. This allows for clearer surveillance for longer and a greater chance of picking up on intruders clothing colours, shoe types etc.
Vandal dome cameras are most ideal for mounting lower down within arm’s reach as they cannot be tampered with and moved in a different direction. This is their main advantage over the other types of cameras and allows for a failsafe security solution in lower down areas of the property. The most common spot for vandal domes is in offices, by porches, and under car ports for example.
Because they’re generally mounted lower down a 2.8mm lens is ideal as it will provide a nice wide field of view of the surrounding area such as your front drive.

This Hikvision camera uses the ONVIF protocol which allows it to be used with third party NVRs that also use the ONVIF protocols. There is no guarantee that these cameras will work on a recorder without the ONVIF protocol.
