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, frame rate settings, and whether you have H.265 encoding enabled or not to save space (We advise turning it on to double the capacity shown below with ease).
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 (to perhaps double or more these figures again).

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 2 Terabytes for a 4 x 4/5MP HD camera setup, as this should give you approx 2 weeks using H.265 @ 20fps and that is on continuous, not motion-detected recording.
(You may only require the full 25 frames per second on certain cameras if things are fast-moving - ie above a till)

Double Electric Gate Automation Kit
The Roger Technology H21 underground motor is the largest belowground electric gate motor in the Roger Technology fleet. The Heavy duty underground gate kit is capable of automating 5m per wing. Features steel cut gears for long life maintenance-free motors. The positive drive system enables full control of the gate throughout the opening and closing cycles.

Electric Motor Features
Reliable and robust: The new gear motor completely made from aluminium die casting with IP67 protection, designed to meet very important installation requirements for swing gates with particular weights and dimensions.
Indestructible and almost invisible: Due to its robust foundation box and the development of the movement of the motor all based on a rack with an adjustable mechanical stop, allows completely linear movement of the suspended completion motor.
The kit uses a hot-dipped, galvanised foundation box with an internal opening and closing limit switches
Foundation box is compact and designed specifically to not intrude on the ground or the public area, available with a cover made from cold-dip galvanised steel and a cover made from AISI 304 stainless steel.
A mains filter should be fitted on the supply to the control panel.
It reduces mains interference and prolongs the life of the PCB.
If you have wooden gates then we strongly recommend the use of our adjustable bracket set as these commercial grade motors come with standard weld-on brackets.
