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)

Fike 505-0004 TwinflexPro2 2 Wire 4 Zone Control Panel (CPR Compliant)
The TwinflexPro2 panel is an intelligent 2-wire panel that utilises a conventional type cabling format. The system is classed as Analogue non-addressable due to the architecture used within the design. The devices communicate with the control panel using the Twinflex data protocol. The TwinflexPro2 panel is available in 2,4 & 8 zone variants which support up to 32 Twinflex devices per circuit. The TwinflexPro2 is able to recognise and separately identify between smoke detector, heat detector and a manual call point alarm.
The panel also monitors each zone for detector head removal, device fault, End of line fault and open or short circuit fault. The panel provides two monitored outputs that may be configured as conventional sounder circuits, a volt free common fire relay and a volt free common fault relay. There are also two multifunction latching/non-latching inputs and one monitored input programmable with options such as Class-Change and Remote fire. The control panel also incorporates an integral power supply unit and requires 2 x 12V 3.2Ah batteries to provide up to 72-hour standby times.
The panel features a 500-event log, day/night mode, alarm confirmation and delay programming options that can be configured using the keypad or via PC driven OSP software. The TwinflexPro2 panel is no longer only compatible with Fike’s Twinflex devices, with the addition of our conventional zone card a 4 or 8 zone panel can now be configured to accept conventional devices on zones 5 to 8.
Unlike most conventional fire alarm systems, which require separate pairs of cables for detector zones and sounder circuits, the Twinflex system requires one 2-core screened cable for each zone to accommodate both detection devices and sounders when using Twinflex devices.
Key Features:
- 4 line x 20 character LCD display
- Ability to differentiate between smoke detector, heat detector or a manual call point alarms
- Alarm confirmation feature
- Available in 2, 4, and 8 zone panel versions
- RS485 Connection to up to 8 Repeater panels
- Highlighted selection menu
- Event log storing up to 500 events
- 3 enhanced test modes
- Allows detectors and sounders to be installed on the same pair of wires
- Up to 32 devices per zone
- Built-in EOL capability in all devices
- 7 modes of detection
- Zone can be configured to day/night detection mode
- Delay programming options
