Normally, RG59 coax cable reaches up to 200m in transmission distance, but there are some limitations or extra settings to take note of during system installation. Most 10Mpbs products on the market only have half duplex capability. If users want to send control signals to an IP camera while the IP camera transmitting digital video, the video stream will be interrupted by the control signals and will result in breaks. However, the users might not be aware of these breaks if the 10Mbps bandwidth is not exhausted.
Enconn identified these limitations and began with the motivation to develop the EoC-INB, a passive 10Mpbs EoC converter with Enconn's unique technology, to achieve full duplex transmission dedicated to IP surveillance.
The EoC-INB passive EoC converter will support upto 20Mpbs throughput bidirectional instead of only 10Mpbs in comparison with other similar products. For high quality HD video, "10Mpbs is not enough" said Dr. Lee, CEO of Enconn. "But for recording capacity consideration and other specific usages, 8Mpbs will be enough and accepted by many system installers."
The Enconn's passive EoC converter supports manual 10Mpbs setting. As this feature is a necessity for the device to work with NVRs, Ethernet switches or IP cameras at a forced 10Mpbs link. If not achieved manually, then the auto negotiation protocol will establish that the link cannot set at 10Mbps and will fail to communicate.
A further drawback with other passive EoC that are currently available on the market is the loop back return issue. When a link is unplugged without impedance matching, it will cause the connected switch to crash.
Enconn has a wide experience in helping users to overcome these types of setting issues. Thus, they have invented the unique technique of their own which has been designed into their Eco-net sereies to prevent the above mentioned problems from occurring during system installation. Other than this, Enconn products offer an alternative but cost-effective solution to help better efficiency and performance of an IP surveillance system with limited bandwidth in transmission.
