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)

The VoiceOFF® "VOX111" is great way to automatically play pre-recorded messages to visitors at your business.
It features a built in PIR that when it detects movement of a person it then plays the pre-recorded message stored in it through a small built in speaker. You can change the message stored in the VOX111 with your own personal one to tailor the message to your particular requirements.
The automatic playing of messages is great reminder to visitors of your policies helping them and your staff to stay safe during the Covid outbreak. It’s non-confrontational and never forgets to do its job!
Ideal for...
- Retail
- Surgeries
- Offices
- Hospitality
- Salons
With the ability to change the built in MP3 message, it’s really easy to then use the VOX111 to play other general messages as times change, so you could use it to welcome guests and take a seat or suggest items you have on special offer.
The VOX111 can also be triggered to play a different MP3 message by triggering its alarm input. This allows you to link it to others devices such as automatic doors, alarm panels, fire alarms etc. Inside the VOX111 it has the ability to store the two MP3 messages, one is played back from being triggered by the PIR, the second being trigged by something external connected to its alarm input.
The VOX111 is an in-ceiling mount design so that it can sit in a ceiling tile or similar for a clean & easy installation. It is 12V powered and requires a suitable PSU such as a POW151. Alternatively you could run a 12V power supply from another 12V system within the premises for a neat installation.
To change the MP3 sound files stored on the VOX111 you simply connect it to a suitable computer or laptop and it will see it as a USB drive. Replace the MP3 files with your own using the correct naming protocol as listed in the VOX111’s instructions.
