Dahua IPC-HDW3649HP-AS-PV-0280B-PRO 6MP WizSense TiOC Pro Eyeball IP Camera (2.8mm, Active Deterrence, Smart Dual Light, Two-Way Audio)
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.

| 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.

Dahua IPC-HDW3649HP-AS-PV-0280B-PRO 6MP WizSense TiOC Pro Eyeball IP Camera (2.8mm, Active Deterrence, Smart Dual Light, Two-Way Audio)
The Dahua IPC-HDW3649HP-AS-PV-0280B-PRO is an advanced 6MP eyeball network camera from Dahua's TiOC Pro (Three-in-One Camera) Series, combining intelligent detection, active deterrence, and full-color surveillance in a single professional security solution. Built around a high-performance progressive CMOS sensor, the camera delivers sharp video at up to 6MP resolution (3288 × 1850), ensuring excellent image quality for identification and evidence collection. As part of Dahua's WizSense AI platform, the camera uses deep-learning algorithms to accurately distinguish humans and vehicles from irrelevant motion, dramatically reducing false alarms. Advanced perimeter protection features including intrusion detection and tripwire detection provide reliable event-based monitoring for commercial, industrial, and residential environments. A key feature of the TiOC Pro series is its active deterrence capability. When an intrusion event is detected, the camera can trigger flashing red and blue warning lights along with customizable audio warnings, helping to discourage potential intruders before incidents escalate. This proactive approach improves site security and reduces response times.
