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)

Hikvision DS-2DT6223-AELY Anti-Corrosive IP PTZ Camera
Hikvision Anti-Corrosion series DS-2DT6223-AELY smart PTZ Cameras is able to effectively avoid acidic and neutral salt fog corrosion. DS-2DT6223-AELY is also able to capture high quality colored images in dim light environment with its low illumination level down to 0.002 lux (color). The embedded 1/1.9" progressive scan CMOS chip makes the true WDR (120dB) and 2.0 MP real-time resolution possible. With the 23× optical zoom day/night lens, the camera offers more details over an expansive area.
The Anti-Corrosion PTZ camera features a wide range of smart functions, including face detection, intrusion detection, line crossing detection and audio exception, benefitting users with a great improvement on security efficiency. These features, combined with smart tracking, enable the camera to detect any progressively moving object and follow it within the camera’s area of coverage without fault. Smart Defog and EIS (Electronic Image Stabilization) are further supported to improve the image quality in challenging conditions
Key Features
- 316L stainless steel enclosure, protecting cameras to be used in corrosive environments, providing reliability and longevity compared to standard cameras
- A built-in heater allows for start-up in ultra-low temperatures to -40℃
- IP67/IK10: water resistant and vandal proof, preventing water ingress for outdoor use
- DarkFighter technology enables the capture of high quality color images in even the dimmest lighting environments
- PTZ: pan-tilt-zoom ability allows the camera to move to view zones of interest
- Up to 23X zoom: zoom to examine subjects of interest within expansive scene
