South Africa is plagued with high crime rates and one area that is experiencing significant losses in particular is the transportation sector. But, active monitoring of vehicles that carry high value cargo is now available.
Goods in transit are vulnerable and attract crime syndicates that are able to take advantage of vehicles that transport cargo between two points due to security loopholes.
Traditionally, the challenge associated with monitoring vehicles is the fact that they are moving and even if a CCTV solution is installed with the ability to view live footage remotely, more than often the bandwidth required to stream the video is insufficient and unstable at best. Transportation companies are turning to technology that delivers live proactive monitoring even in low bandwidth areas, enabling swift and preventative action to be taken should an incident occur.
For example, SerVision’s mobile DVRs provide mobile video gateways that make use of cellular and wireless technologies to stream high-quality live or recorded video to mobile devices or centralised control rooms. This ensures proactive security with trucks carrying goods, especially in dangerous areas or environments.
Remote users are able to locate and track vehicles with full GPS support and the anti-shock, vibration resistant DVR chassis ensures complete reliability while on the move. Up to four cameras can be connected to each DVR unit as well as sensors connected to doors of vehicles further improve the monitoring of vehicles from a centralised control room. USB modems allows for video to be constantly streamed while built-in WiFi enables wireless backup of stored video to be sent to a storage server.
‚”Swift and immediate action is essential in this day and age when vehicles are hi-jacked and stock is stolen,” says Mark Chertkow, Managing Director at GIT. “”It is crucial to be able to actively monitor the location and nature of a crime as and when it happens to ensure the capture and conviction of perpetrators. The high compression rate allows for video footage to be streamed using less bandwidth and offers real-time image capture and streaming. These aspects are essential to ensure action can be taken as quickly as possible.‚””
The compression capabilities offered by SerVision allows for DVRs to stream video using any mobile data available, from GPRS to 3G. The compression technology makes transmission of video at four frames per second (4fps) possible at data rates as low as 1 Kilobyte per second (KB/s). This ensures recording and streaming of video even when out of 3G areas where only Edge or GPRS signal is available, making it ideal for the SA market when considering that 3G coverage is restricted to mostly metropolitan hubs. The built-in WiFi has the significant benefit that ensures the cost of monitoring footage does not incur data costs when viewed over the WiFi link.
Transcoding also allows for recording to take place at a high resolution and gives users the ability and choice to view this footage at a high or low resolution on demand.
‚””It is essential that a more proactive approach to security monitoring is taken and furthermore to ensure evidence is available to law enforcement during and after an event,”” says Chertkow. “”Live streaming and surveillance that delivers outside of 3G overage areas enables logistics companies to offer a comprehensive approach to protection as well as improved control to further protect trucks, goods-in-transit as well as people.‚””
Planet Radio TV tune in on any device
Planet Radio TV plans to be Africa’s first online broadcaster that allows its listeners to watch via Internet and satellite TV as well as listen via FM or Internet radio. SEAN BACHER visits its studios.
Planet Radio TV (PRTV) is broadcast much like any other terrestrial radio station, allowing its users to tune into it with a standard FM tuner. But its owner, Planet Image Productions, is about to launch two other means of tuning into the station.
In the coming month, MultiChoice will place a new satellite in orbit that will, by the new year, allow Planet to broadcast to subscribers via the satellite. Planet has also announced the PRTV app, which can be downloaded to Apple, BlackBerry, Android and Windows Mobile devices, allowing users to stream the content to their phones and tablets.
‚”What makes this unique though is that our systems will automatically detect a user’s connection speed and stream content in a format that suits that speed, says Planet Image CEO Wale Akinlabi. ‚”For example, someone connecting through 3G will be able to view high-definition video and hear high-definition audio. A user with a slower connection will still be able to view and listen to the station, but at a lower quality.‚”
This, he believes, will eliminate the buffering issue which discourages many users from streaming video and audio to their devices.
The radio station comprises 80% African music, with the remainder being international, and is targeted at Africa’s youth.
‚”At PRTV we intend to change the way consumers view, listen and interact with television, radio and Internet mediums,‚” says Mabel Mabaso, chief operations officer and director at Planet Image. ‚”It is an exciting platform that synchronises three mediums, providing opportunities for consumers and advertisers alike.‚”
Planet RadioTV differentiates itself from other local broadcasters with its clever use of software and hardware. Planet Image uses a high-definition video-graphics (HDVG) rendering program, designed by Orad, an Israeli company specialising in TV production software. This software suite, combined with four Panasonic high-definition cameras, is able to detect and focus on a person’s voice. When the camera fixes on a voice, that camera is automatically activated and begins broadcasting. Should someone else begin talking, a separate camera will detect the voice and focus on that person.
The software controlling the cameras also performs basic video editing. Mabaso says that, although the initial cost of the equipment was more than that of standard cameras, it will prove well worth it, as it eliminates the need for a dedicated cameraman filming the show in the studio.
‚”Another payoff is that we don’t need that much office space,‚” she says.
Based in Randburg in Johannesburg, the studio is small in comparison to most others and the control room is just big enough for one person.
‚”The control room merely serves as a back-up should one of the cameras fail. It also allows us to control when and where visual adverts appear.‚”
The system is also tightly integrated with applications like Skype.
‚”We can interview someone overseas without having to send a crew there to perform recording. We simply communicate via Skype, making the interviewee’s Internet camera an extension of our own in-studio cameras.‚”
Besides featuring local and international music, the station has regular fashion, food and cooking, music and culture segments, which are broadcast to around 30 000 listeners around Africa.
Rounding up the technology aspect, PRTV has integrated Twitter and Facebook, allowing its listeners to interact with DJs.

The EOS M is available in sleek black, glossy white, stylish silver or bold red colours, and condenses Canon’s EOS imaging heritage into a stylish, compact design. The model launches alongside two new lenses, the EF-M 22mm f/2 STM pancake and the EF-M 18-55mm f/3.5-5.6 IS STM standard zoom, as well as a new compact EX Speedlite the Speedlite 90EX. For those who want to push their images even further, the EOS M can also use Canon’s range of EF lenses with the new Mount Adapter EF-EOS M, for even more creative freedom.
The quality of a Canon DSLR
The EOS M’s high-resolution, 18 megapixel APS-C hybrid CMOS sensor also allows you to blur the background for beautiful portraits, or for close-ups with impact.
With the inclusion of Canon’s DIGIC 5 processor, colours ‚’pop’ and skin tones are beautifully natural, while a super-fast shutter allows you to capture split-second action.
Shoot what you see and easily express your creative vision
Every aspect of the EOS M has been designed to make it simple to capture high-quality images. With the high-resolution, 7.7cm (3.0‚”), Clear View LCD II Touch screen, the EOS M gives you as much or as little control over your photos as desired. Simply select different shooting modes and settings via the on-screen icons, or let Scene Intelligent Auto adjust the camera settings according to the subject and shooting conditions, leaving you free to focus on composition and selecting the perfect moment to hit the shutter release button.
Turn film-maker with EOS Movie and Video Snapshot
When a moment calls for more than a still image, the EOS M lets you switch to Full HD video with stereo sound.
Extending the EOS System with dedicated accessories
In addition to compatibility with Canon’s existing EF lenses, accessories and Speedlites, the EOS M launches with its own range of accessories. Two new EF-M lenses offer portability and high performance when using the new model the EF-M 18-55mm f/3.5-5.6 IS STM standard zoom and the EF-M 22mm f/2 STM pancake lens. Both feature new stepper motor technology for exceptionally smooth AF performance, as well as precision Canon optics, while their compact designs offer the perfect form-factor to complement the camera’s pocket-sized body.
