Haydon HAY-RJ45STRAIN50BLK RJ45 Cat5e/Cat6 Strain Relief Boots – Black Network Cable Protection Sleeves – Pack of 50
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 |

| 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-RJ45STRAIN50BLK RJ45 Cat5e/Cat6 Strain Relief Boots – Black Network Cable Protection Sleeves – Pack of 50
The Haydon HAY-RJ45STRAIN50BLK RJ45 Cat5e/Cat6 Strain Relief Boots are professional-grade cable protection accessories designed to improve the durability and reliability of Cat5e and Cat6 Ethernet cable assemblies. Suitable for structured cabling, CCTV, IP surveillance, telecommunications and general networking applications, these black strain relief boots help protect RJ45 connector terminations from excessive bending, pulling and everyday mechanical stress.
Manufactured from a robust and flexible polymer, each boot slides onto the network cable before the RJ45 connector is crimped into place. Once installed, it provides additional support where the cable enters the connector, helping to reduce cable fatigue, minimise stress on the conductors and extend the lifespan of the finished cable assembly.
The black finish offers a discreet, professional appearance that is ideal for data cabinets, patch panels, server racks and network installations where consistent cable identification or colour coding is required. The flexible design ensures quick installation without affecting the performance or accessibility of the RJ45 connector.
Compatible with standard RJ45 Cat5e and Cat6 connectors, the HAY-RJ45STRAIN50BLK is ideal for manufacturing custom patch leads, repairing Ethernet cables and completing new network installations. Whether used by IT engineers, network installers, security professionals or electrical contractors, these boots provide an effective solution for protecting cable terminations in residential, commercial and industrial environments.
