"Solar power x Lithium ion battery" to support general purpose demand
Enhanced IT infrastructures have resulted in the recent popularization of network cameras used for monitoring. However, these have up until now required utility power or lead-acid storage batteries as power sources, which have restricted the locations in which these can be installed, as well as usage duration. Additionally, there were various issues regarding costs for permanent operation that needed to be resolved. As a result, TBM established know-how to guarantee a steady and reliable power source by combining solar panels#*1# and lithium-ion batteries,#*2 and transmit video taken using a network camera#*3# using the FOMA#*4# service. This resulted in the PowerNES system for surveillance cameras that can meet all remote monitoring needs.
This combines solar panels with small or medium-sized lithium-ion batteries, as well as 3G mobile communications and network cameras, creating a breakthrough remote monitoring system that is both low cost and general-purpose.
No external power supply needed
-- operates using only solar panels and lithium-ion batteries
This achieves constant operation using 60W solar panels and lithium-ion batteries, with no costs for connected power required.
No telecommunications wiring needed, using FOMA for simplified remote monitoring
The built-in router incorporating a FOMA transmission module means video from the network camera can be viewed on computers. Periodically taken still images can be viewed on a PC, and live video (with time restrictions) can be viewed in real time. Because this uses mobile communications, there is no need for installation of telephone or other wiring.
Provides a low-cost ASP service that stores image data
The PowerNES system for surveillance cameras provides a diverse range of benefits at a low price, including 1) straightforward installation, 2) low initial investment, 3) no need for an administrator, 4) ASP service#*5# that does not require recording capabilities. Furthermore, the ASP service prevents duplicate backups of recorded data.
[System Configuration]
*Solar panel: 60W *Lithium-ion battery
*Charge/discharge device (operation without sunshine: 7 days)
*Camera still image transmission method: FOMA (wireless LAN [under study])
*Data-center image-retention service (ASP service)
Notes
*1)Solar panel: These are panels that connect multiple photovoltaic cells together to obtain the required voltage and current, meaning replacement of batteries and power supply wiring are not needed. These are also referred to as photovoltaic panels and photovoltaic modules.
*2)Lithium-ion battery: These are rechargeable batteries that use lithium ions as the conductor within the electrolyte. These feature 1) low self-discharge rates, 2) no memory effect, and 3) high capacity at a light weight. These are different to lithium primary batteries that use lithium-ion compounds.
*3)Network camera: This is a two-way camera with its own IP address directly connected to the network, and that can transmit image and audio data. This is also referred to as an IP camera (Internet Protocol) camera.
*4)FOMA These use NTT Docomo's third-generation (3G) mobile communication system and are resistant to interference and noise, enabling high-speed access. FOMA can be used anywhere with FOMA service. "FOMA" is an abbreviation of "Freedom Of Mobile multimedia Access."
*5)ASP (application service provider): This is service that rents out business applications over the Internet.
