Veracity Network Devices include PoE switches, LAN Extenders and PoE forwarders, PoE mid-spans and spitters.
The LAN and PoE Extenders make possible the extension of power and data beyond the 100m limit of the Ethernet and PoE standards.
Veracity Timenet is an NTP master reference clock for CCTV & DVR applications. Timenet provides a low-cost solution to the problem of providing accurate reference time signals for CCTV recording equipment The unit integrates a GPS receiver and master NTP clock server into a single device which can be directly connected to the network.
A new version of Timenet available shortly also provides position data (latitude, longitude and altitude).

[1] Megapixel Cameras
CCTV cable is normally routed to a central point, forming an effective single “star” network topology. Exploitation of legacy video cable with Veracity Highwire Adapters actually solves a major problem with megapixel cameras – that of the high network bandwidth requirements for such devices.
In this application, a high-resolution megapixel IP camera replaces a standard analogue CCTV video camera. The IP camera’s standard Ethernet TCP/IP connection is linked to a Veracity Highwire Adapter with a short CAT5 patch cable (straight through or cross-over). Both the camera and the Highwire Adapter are powered from the same power supply, and both may be fitted inside a standard external camera housing. The Highwire Adapter link runs across the existing installed 75-ohm co-axial video cable, and the rest of the network is connected at the other end (usually, but not necessarily, a control room or equipment room). One, several or many such links may feed into the network to an NVR (network video recorder). As the network link is full speed and fully transparent, the IP camera appears on the network as a completely normal IP connection.
[2] Multiple IP Cameras
In this application, multiple IP cameras replace a single analogue CCTV video camera. The IP cameras are connected to a small network switch. One port of the switch is linked to a Highwire Adapter. Again, the Highwire Adapter link runs across the existing installed 75-ohm co-axial video cable, and the rest of the network is connected at the other end which again, usually includes one or more network video recording systems, which “see” the cameras as if they were connected over Ethernet cable.
[3] General Application
In a completely general application, any network device is connected across a length of co-axial video cable. An example might be a Gatehouse located remotely from the main building, connected only with a video cable (perhaps originally laid-in for a night-guard to view a camera). Now this legacy cabling can be turned into a full 100BaseT network connection and used for any network communication purpose required (IP cameras, PCs, printers, network controllers, voice-over-IP systems in fact any Ethernet equipment of any type).
