Haydon HAY-PSU-4WAY-SPLIT 4-Way CCTV Power Splitter Cable with 2.1mm DC Connectors
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.

| 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.

Haydon HAY-PSU-4WAY-SPLIT 4-Way CCTV Power Splitter Cable with 2.1mm DC Connectors
The Haydon HAY-PSU-4WAY-SPLIT is a professional 4-way DC power splitter cable designed to distribute power from a single inline CCTV power supply to multiple devices. Ideal for surveillance installations, the splitter converts one standard 2.1mm DC power output into four individual outputs, allowing installers to power several cameras from a single compatible power supply.
The cable features one female 2.1mm DC input connector that connects directly to a compatible Haydon inline power supply, together with four male 2.1mm DC output connectors for connection to CCTV cameras, video transmitters or other compatible 12V DC equipment. This straightforward plug-and-play design reduces installation time while eliminating the need for additional wiring or junction boxes.
With an overall cable length of approximately 400mm (40cm), the splitter provides sufficient flexibility for neatly routing power leads within CCTV installations. It is particularly suitable for applications where several cameras are installed in close proximity, such as retail premises, offices, warehouses, reception areas and residential properties.
