veracity HIGHWIRE POWERSTAR DUO VHW-HWPS-C2
- CCTV Lens Guide
- Hard Drive Size Guide
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)

- Reuses existing coax cable for 2 IP cameras or devices
- Integrated 2 port PoE switch (PoE plus with local power option)
- Eliminates separate power cabling with PoE over Coax
- Compatible with all HIGHWIRE Powerstar Base units (1, 4 & 8ch)
- Instantly check connection and power level with Safeview
- Completely automatic connection, no configuration required
- 100BaseTX performance over 300m of RG59 (500m on RG11)
HIGHWIRE Powerstar Duo makes the most of your legacy cabling and multiplies its capability by connecting two IP cameras or other network devices.
Ethernet over Coax HIGHWIRE Powerstar Duo’s unique ultra low-power design and efficient power delivery enables long range Ethernet over coax. It works even over the lowest grade cable, such as the high-resistance, copper-clad steel (CCS) types found in many legacy installations. This means that legacy coax upgrades can be planned with confidence, while a quick check of the SafeView™ power level display reaffirms that the device connections will continue to be reliable, whatever the cable used.
For predictable network operation with no restrictions, HIGHWIRE technology delivers a full 200Mbit/s of bandwidth at 300m (1000 ft) of RG-59 or 500m (1600 ft) of RG-11 coax. For full information on POE-over-Coax™ distances achievable, please refer to the Range Table in the HIGHWIRE Powerstar datasheet or on the Veracity website.
HIGHWIRE Powerstar DUO The DUO variant of HIGHWIRE is designed for the camera end of the coax and, with an integrated two-port POE switch, enables connection of two IP cameras over a single coax. With no need to configure IP addresses, set DIP switches, or make awkward measurements and calculations, installing HIGHWIRE Powerstar Duo is simple. The Base end of the coax is driven by single-channel, 4-channel or 8-channel HIGHWIRE Powerstar Base unit. The DUO unit can be powered either by POE over coax, delivering a maximum total POE power budget of 25 watts, or by one of the optional local PSUs, delivering 40 or 78 watts.
HIGHWIRE Powerstar Duo features Veracity’s unique SafeView™ display, to provide IP camera installers with an instant and very easy-to-understand confirmation of correct operation from either end of the cable.
POE over Coax or Local Power In the simplest implementation the BASE unit receives power from a standard POE switch or Veracity’s 57V DC PSU and transmits POE over the coax. This is shown in the diagram below. The DUO unit receives this power and delivers up to 25 watts shared between two IP cameras. No external power cabling is required, and all detection and setup occurs automatically. For higher POE power budgets, an optional Veracity 57V DC PSU may be used to power the DUO locally at the camera end delivering 40 watts or 78 watts depending on PSU model.
