There are over 40 million analog surveillance cameras in operation around the world, the vast majority of them being connected using coax cable. As operators replace these aging cameras with modern digital cameras, they also have the problem of either having to replace the coax cable, or finding a way to reuse the existing cable. The AT-MC606 connects an Ethernet or Fast Ethernet UTP connection over a coax cable at distances up to 2km. Operating in an asymmetrical mode, the high upsteam bandwidth is used to carry the video data, whilst the smaller downsteam bandwidth is used to transport camera commands. Given the bandwidth that a pair of AT-MC606 can transmit, multiple digital cameras can be connected over a single coax cable when used in conjunction with an Ethernet switch.
Extended Ethernet operation
Used as a pair, the AT-MC606 provides up to 100Mbps of data transfer via a BNC connector. Standard Ethernet operation is preserved end to-end, retaining VLAN tags, and Ethernet Mac information across the link, while higher layer protocols are passed transparently. Cable length of up to 2km can be supported by the AT-MC606.
Plug and Play operation
Simply connect to the RJ-45 Ethernet port and the unit will automatically auto-sense and configure for 10T or 10/100TX, as well as full or half-duplex Ethernet operation. The async mode is useful for IP surveillance modes, as it allows downstream information to be sent to the camera - which required minimal bandwidth, whilst giving the maximum bandwidth to the upstream channel for video being sent to the servers. With this amount of bandwidth, a single existing coax cable can support multiple IP cameras, if they are connected via a switch to the AT-MC606.
The AT-MC606 is a perfect fit for the IP surveillance market. Many already installed analog cameras use a coax cable to connect cameras back to the control center or encoder. When these cameras need replacing - they are increasingly being replaced by digital cameras. Digital cameras do not allow connectivity over coax cables, so either the camera and cable needs to be upgraded, or the existing cable can be used if an AT-MC606 is installed at either end of the cable, saving the cost of running all cabling.
Advantages of IP cameras over analogProduct Highlights
Cameras can provide higher quality images up to multi-mega pixel HD type formats. As the data is sent in a digital format, there is no signal quality degradation in transmission. Installation is easier, as the camera can use PoE to power the camera, instead of having to use a separate power cable. Also, analog PZT cameras also need additional cabling, with each function being carried on a separate cable. With IP camera, all info is carried on a single Ethernet cable.
