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)

DS-PRI120 security radar, which adopts phased array technology, pulse doppler and low-power FMCW modulation technology for intrusion detection. It supports multi-target positioning, tracing and multiple linked camera tracking. Through intelligent algorithm analysis, it can filter out false alarms under various circumstances. It can work properly day and night in various environments, such as rain, fog, and so on. It is mainly used in the military base, prison, power station, railway, museum, airport and other security places.
- Detection angle: 120°
- Detection range: 120m
- Line crossing(Max. 4 trigger lines) and Zone alarm(Max. 16 Zones)
- Selectable frequency band
- Links up to 4 speed domes for auto target-tracking and the speed domes can be mounted separately
- Links multiple network cameras for alarm capturing via iVMS-4200
- Function of radar-speed dome linkage: smooth stream*, mandatory switch of speed dome tracking target , parking action and field of view display for each speed dome
- Multiple radars can link to one-speed dome
- Up to 4 targets can be tracked by 4-speed domes respectively
- User interface optimization: visible zone drawing path, movable zone, addible zone polygon vertex, alterable zone shape
- movable trigger line(whole line or one endpoint), editable trigger line length, and configurable trigger line direction
- Capable to detect ultra-slow movements, squatting movements or creeping
- Displays the distance, direction, and position of the detected object on the client software
- Selectable applications including open mode, shrub mode, and custom mode (with adjustable sensitivity)
- 24/7 all-weather working properly
