General
Output current	700 mA

The AXIS accessory power supply, type T8003 PS57, is a specific power supply device for the AXIS T8640 Coax Over Ethernet adapter. It provides power to the entire system by supplying energy to the connection between the base and device unit as well as to the connected PoE camera. This eliminates the need for a separate midspan, simplifying installation and reducing the number of required components. The power supply can be connected either at the base end or at the device end of the Coax Over Ethernet adapter, allowing flexible use in various application scenarios.

Applications

The AXIS T8003 PS57 is primarily designed for use in security camera systems, particularly in environments where existing coaxial cables are used for transmitting network data. It enables the integration of PoE cameras into existing surveillance infrastructures without requiring additional power supply cables to be installed. The application is especially beneficial in buildings with already installed coaxial cables, where switching to Ethernet cabling is not economically or technically feasible.

Functions and Features in Detail

The power supply delivers a maximum power output of 30 W, sufficient to power a PoE camera as well as the connected device unit of the AXIS T8640 adapter. Power is supplied via the network cable (PoE), enabling simultaneous power and data delivery to the camera and adapter unit. The connection option at the device end allows for flexible installation, particularly when the base station already has its own power supply. The maximum current output is 700 mA, which is sufficient for most PoE cameras.

Technology Explained Simply

The AXIS T8003 PS57 operates as an AC adapter, converting mains voltage into a direct voltage suitable for PoE technology. Power is delivered through the coaxial cable, which in the AXIS T8640 adapter carries Ethernet signals. This method, known as Coax Over Ethernet (CoE), utilizes existing coaxial cables to transmit network data, eliminating the need for new Ethernet cabling. The power supply ensures that the connected PoE camera and adapter unit are adequately powered without requiring additional power sources.

Compatibility and Accessories

The AXIS T8003 PS57 is specifically developed for use with the AXIS T8640 Coax Over Ethernet adapter. It is compatible with PoE cameras that do not exceed a maximum power consumption of 30 W. The quality and bandwidth characteristics of the coaxial cable influence the efficiency of power transmission, so selecting an appropriate cable is recommended.

Mounting and Installation

Installation is performed by connecting the power supply to either the base or device end of the AXIS T8640 adapter. Power is transmitted via the coaxial cable, supplying energy to the PoE camera and adapter unit. It is important that the coaxial cables have sufficient quality to ensure reliable power transmission. Mounting does not require special tools, but proper cable connections are necessary to ensure stable power supply.

Application in Operation

The AXIS T8003 PS57 enables efficient and cost-effective integration of PoE cameras into existing surveillance systems. Reducing the number of required power supply components simplifies installation and lowers overall costs. Power delivery via coaxial cable reduces the number of necessary cables and simplifies maintenance. The maximum power output of 30 W is sufficient for most PoE cameras, ensuring broad compatibility. The flexible connection option at either the base or device end provides additional flexibility in system planning and installation.
