Dahua IPC-HDW3841EMP-S-0360B-S2 8MP WizSense IR Fixed-Focal Eyeball Network Camera (3.6mm, 4K UHD, AI Human & Vehicle Detection)
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 |
| 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.

The Dahua IPC-HDW3841EMP-S-0360B-S2 is a high-performance 8MP eyeball network camera designed to deliver ultra-high-definition surveillance for residential, commercial, and industrial environments. Equipped with a 1/2.8" progressive CMOS sensor, the camera captures video at resolutions up to , providing exceptional image detail for identification, monitoring, and evidence collection. As part of Dahua's WizSense Series, the camera incorporates advanced AI-powered analytics, including human and vehicle classification. Intelligent perimeter protection functions such as intrusion detection and tripwire detection help reduce false alarms by accurately distinguishing people and vehicles from irrelevant motion sources. The camera also supports SMD 4.0 and AI Scene Self-Adaptation (AI SSA) for enhanced detection accuracy and image optimization. The integrated Smart IR system provides night vision coverage up to 30 meters, automatically adjusting infrared intensity to prevent overexposure of nearby objects. Combined with 120dB True WDR, 3D Noise Reduction, HLC, and BLC, the camera delivers clear images in challenging lighting conditions, including strong backlighting and low-light environments.
