- CCTV Lens Guide
- Hard Drive Size Guide
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.

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 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.

Battery-Powered Baby Monitor with crying detection, out-of-crib alert, auto-play smoothing music, and 2000 mAh battery
- Detection of baby movement and adjustable detection range: Powered by AI algorithm, this baby camera allows you to observe your baby's movement at any time. You can adjust the detection area (e.g., the cot), and you will be immediately notified when the baby leaves the area.
- Automatic playback of soothing music and cry detection: When your baby cries, you will receive a message, and if you can't reach the baby immediately, the baby monitor automatically plays soothing music to calm your baby. In addition, you can talk to your baby through the camera as if they were right next to you.
- Safe materials and 100% wireless: Made of non-toxic silicone material, this baby monitor has no sharp edges on the body, making it safe to use in the nursery. The 100% wireless setup also protects curious children from dangerous cables.
- No visible red IR light and 2000mAh battery operated: This baby monitor provides clear night vision without disturbing the baby's sleep by using a flashing IR light. Although one of the smallest battery cameras on the market, it optimizes its response time to guarantee the detection of baby activities overnight.
- Flexible memory: The baby monitor is equipped with a microSD card slot that supports up to 256 GB. If additional backup is required, subscription-based, but not mandatory cloud storage options are also available. (SD card sold separately)
