HIGHWIRE Powerstar Base 4 replaces existing analogue video encoders and enables easy replacement of analogue cameras with high-resolution IP cameras. The HIGHWIRE Powerstar product family offers reliable power delivery and long-range extension even over low-grade coaxial cable and now enables direct replacement of existing analogue video encoders to allow cost-effective upgrade to IP cameras.
Existing Video Encoders
Many CCTV installations made the first step to IP video by using analogue video encoders to digitise their existing analogue cameras and stream IP video onto their network. This allowed the analogue cameras running over existing coaxial cables to be used with modern network video recorders (NVRs) and to be streamed anywhere on the network (to a video wall, operator screen or display monitor for example). Video encoders were frequently used to get the video onto a network at the most convenient point thus avoiding having to run coax cable very long distances all the way to the equipment room end. Digitising and networking the video also added some flexibility to the system in terms of how the video data was routed and used, and indeed this is part of the power of IP Video systems.
Legacy Video Encoders
Existing video encoders come in many forms, but by far the most common is the stand-alone four-channel encoder, as manufactured by hundreds of different companies around the world. All have very similar characteristics: Four BNC connections for the coax cables, a network connection and a power connection.
PTZ Control/Audio
Some video encoders also had RS232 or RS485 ports for controlling analogue PTZ cameras. Of course, such serial connections are not required for IP PTZ cameras, as all control signals go through the Ethernet network connection along with the digital video. Likewise, some analogue encoders had audio I/O, but again, separate audio connections are not required for IP cameras, as the signals are incorporated into the network data and recorded by the NVR. HIGHWIRE Powerstar Base 4 directly replaces the analogue encoder unit.
Direct Encoder Replacement
HIGHWIRE Powerstar Base 4 builds on the market-leading HIGHWIRE range of Ethernet-over-coax (EOC) adaptors from Veracity, and is designed as a direct replacement for legacy analogue video encoders.
EOC Base and Camera Units
In Diagram 2 above, the legacy analogue encoder is replaced by a HIGHWIRE Base 4 unit and the coax cables are connected to four separate single-channel HIGHWIRE Powerstar Camera adaptors. Note that Duo and Quad Camera adaptors are also The low-resolution, locally powered analogue cameras are replaced by high-resolution POE powered IP cameras. A Gigabit Ethernet uplink connection on the HIGHWIRE Base 4 ensures there is no network bandwidth limit on image quality and resolution.
Automatic Connection
As soon as the power is supplied to the Base 4 unit, a connection is established automatically with the Camera units, the IP cameras are powered up and the camera IP addresses will be on the network. The HIGHWIRE units require no configuration, do not require IP address settings and are completely transparent to the network.
Power Supply Included
The Encoder Replacement Kit includes a 57V DC, 1500mA power supply for the 4-channel HIGHWIRE Powerstar Base unit. This provides a total power budget of 80W for the Base unit, 4 camera units and powered devices (IP cameras). This power is sufficient to run four full POE 802.3af IP camera devices, or to provide a total POE output budget across the four HIGHWIRE Powerstar Camera devices of 70W, with an individual maximum of 25W per Camera unit.
POE-Over-Coax™ Range
HIGHWIRE Powerstar delivers reliable power at long range, even over low grade CCS cable. No set-up is required and the coax connection is automatically established on power-up. The table shows the range achievable by cable type and camera wattage.
