Through the use of a SIM card, SingTel also provides connectivity to closed-circuit televisions (CCTVs) which are mounted at locations without fixed Internet connection.
This means video footage from these devices can be streamed back to the main system, the spokesperson said. If the mobile network is congested, users can adjust the video bitrate accordingly to ensure continuous streaming. The low bitrate images can later be enhanced for clearer viewing, he noted.

Both Gemalto and Singapore company Power Automation also worked together to implement M2M-enabled power meters at the National University of Singapore's UTown Residence.
See Gim Kerk, director of engineering at Power Automation, explained the smart meter tracks the use of electricity in the hostel and, by doing so, is equipped to offer residents to purchase electricity credits for air conditioners in their rooms.
The meters display residents' remaining credits, send messages for them to buy more credits when it is running low, as well as display real-time loading and warnings for impending electrical trips, See said.
Lakhi Baug, M2M sales manager for Asia at Gemalto, added the smart meters are embedded with mobile connectivity so they can connect to a server which collects the usage data, enable real-time feedback to the service provider and control parameters to facilitate the efficient distribution of electricity.
Besides efficient power management, the smart meters reduce manpower cost as they eliminate the need for staff to visit the hostel to take physical meter reading.

NUS is also the home of the single-seater, micro-electric vehicle. The university has partnered Toyota Tsusho Asia-Pacific to research the viability of such vehicles for short travel distances.
Richard Lee, general manager for the IT and Electronics Department at Toyota Tsusho Asia-Pacific, explained that M2M is used in this research project to manage the fleet of vehicles as part of a car-sharing scheme. The data transmitted to backend servers helps track and monitor the performance and location of these vehicles, he said.
