Haydon HAY-FRSH Red Fire Cable Shrouds – Pack of 10 for M20 Fire Cable Glands
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-FRSH Red Fire Cable Shrouds – Pack of 10 for M20 Fire Cable Glands
The Haydon HAY-FRSH Fire Cable Shrouds are a practical accessory designed to improve the appearance, protection and identification of fire alarm cable installations. Supplied as a convenient pack of 10, these high-visibility red shrouds fit over standard M20 cable glands, providing a clean and professional finish while helping to protect cable gland assemblies from dust, dirt and other contaminants during installation and ongoing maintenance.
Manufactured from durable soft PVC (vinyl), each shroud offers flexibility for quick installation while maintaining a secure fit around the gland body. The bright RAL 3020 red finish allows installers and maintenance engineers to quickly identify fire alarm cabling, supporting good installation practice and making routine servicing easier in busy plant rooms, risers and electrical cupboards.
With an internal diameter of 21mm and a length of 138mm, the HAY-FRSH is designed specifically for compatibility with standard M20 threaded cable glands commonly used in fire alarm and life safety systems. By covering the exposed gland assembly, the shrouds help reduce the accumulation of debris around cable entries while enhancing the overall appearance of the installation.
