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.

Resolution (Megapixels) |
Days of storage provided by 1TB per camera (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (50% motion- 15 frames per second) |
|---|---|---|---|
| 1 | 44 | 11 | 36 |
| 2 | 22 | 5 | 18 |
| 3 | 17 | 4 | 14 |
| 4 | 11 | 3 | 9 |
| 5 | 9 | 2 | 8 |
| 6 | 8 | 2 | 6 |
| 8 (4K) | 5 | 1 | 4 |
| 12 | 4 | 0.5 | 3 |
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.

Pyronix KX 15m Dual Tech Triple LED PIR Detector KX15DT3
Ideal internal detection for any room. Fit the wired KX15DT and the user can rest assured that they have great detection and protection for their property.
Consisting of both a Passive Infrared (PIR) and microwave sensor in one housing, both sensors need to be activated simultaneously to get an alarm condition. This increases stability and makes the KX15DT ready to detect in even the harshest environments
Allows the detector to operate as a standard DT detector in ‘AND’ mode,
or as a microwave detector, in environments where there is risk of the
PIR being blocked, in ‘OR’ mode.
Volumetric detection allows for a large area to be covered by the detector and is ideally suited for living rooms, dining rooms, kitchens, bedrooms and more. On top of this they are discreet and will not look out of place with the rest of the house.
3mm polished finish produces a professional and sleek finish while reducing electrostatic interference on the PIR sensor. On top of this, sealed optics protect the detector from insect infestation, shields air movement, and protects against reflections from inside the detector housing.
Triple LED indication indicates the detection technologies as they detect, with orange indicating ‘microwave, green indicating ‘PIR’ and blue indicating an alarm activation.
Specifications:
- Dual technology detector using PIR and Microwave sensors
- Selectable EOL (End Of Line) resistors
- AND/OR technology
- Patented Independent Floating Thresholds (IFT)
- Blue Wave Technology
- Auto sensitivity feature and digital temperature compensation
- Triple LED indication
- Different frequency options avoiding microwave crosstalk
- Sealed optics
- Tamper proof brackets included
