Veracity HIGHWIRE VHW-HW
- 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)

- Uses legacy cabling - cuts installation costs
- HIGHWIRE supports HD & Mega-Pixel cameras
- Fully transparent duplex 100Base-T Ethernet
- Simple to install - no IP address or other setup
- Up to 300 metres on RG59, or 500 metres on RG11
- 12-40V DC or 24V AC power input
The Veracity HIGHWIRE VHW-HW is a single Ethernet over co-axial video device. It has a standard RJ-45 network connector one side and a co-axial BNC connector on the other. Used in pairs, one Highwire unit is attached at each end of a co-axial video cable by BNC connectors providing a straight RJ-45 to RJ-45 Ethernet connection from its opposite end.
The HIGHWIRE unit is designed to utilise existing legacy co-axial video cabling allowing you to migrate to digital IP CCTV without having to install any new cabling. This enables your original investment to be retained saving installation time and costs.
Easy to install, the Highwire VHW-HW needs no network configuration and is completely transparent to other devices on the network. Simply plug in and your co-ax video cable becomes part of your Ethernet network offering full speeds of up to 200Mbps.
Veracity HIGHWIRE VHW-HW – Key benefits:
- Legacy co-axial video cabling can be retained and used for new generation digital IP CCTV surveillance applications providing significant cost savings
- High transfer rate of 200Mbps (max.) allows the use of megapixel or multiple IP cameras to run from a single connection
Veracity HIGHWIRE VHW-HW – Key features:
- Uses legacy analogue video cabling cutting installation costs
- High transfer speed allows megapixel cameras or multiple IP cameras to run across a single co-ax cable connection
- Fully transparent. Will fully support any network device. Highwire is non-detectable on the network
- Simple to install. The Highwire VHW-HW requires no network configuration, has no IP or MAC address
- Can operate at a maximum length of 300m, full speed of 200mbps at lengths of 200m or less
- Auto adapts. Where cable length, quality or interference prevents full rate operation (200Mbps) the device will auto-adapt lowering the total bandwidth as necessary
- Compact and low power. Designed to fit inside camera housings and use the camera power supply (please have an electrician check supply voltages before using camera supply to power Highwire unit)
Veracity HIGHWIRE VHW-HW – Typical applications:
- Ideal for migrating from analogue CCTV to digital IP CCTV systems. Allows the use of existing analogue co-axial cables reducing installation time and costs
Veracity HIGHWIRE VHW-HW – Key technical indicators:
- Analogue interface: BNC connector 75ohm, up to 300m (200m for full data rate)
- Data throughput max.: 200Mbps (total up + down). Auto-adaptation to cable conditions
- Ethernet interface: RJ-45, straight-through or cross-over (auto detected), 100BaseT/10BaseT, full/half duplex with auto negotiation
- Operating voltage: Nominal 12V DC (9-24V working range) or 24V AC (type and polarity auto detected)
- Supply current: 200mA (12V), 100mA (24V)
- Operating temperature: -10°C to 50°C
