Solar Power Farm - Western Samoa

Snowgrass Solutions was approached to install one of their rental solar powered time-lapse cameras to record remotely, the construction of a solar power farm in Western Samoa.
The system operated on Samoa's mobile 3G network and sent the images back to New Zealand.
Upon completion of the project, the time-lapse movie was created and returned, via the Internet, to Western Samoa where it was displayed at the official opening of the farm.
Two movies were created. Long and short versions were created for the customer.

The above YouTube movie has excessive compression applied. The original 720HD movie was crisp and very clear.


Christchurch's new Justice and Emergency Services Precinct

Christchurch Justice and Emergency Services Precinct

Snowgrass Solutions installed a network of cameras surrounding the Justice Precinct construction site.
A master site was fitted with a Snowgrass 3G router and wireless network that the other cameras communicated back to the Internet via.
Images were saved at regular intervals for the later production of a timelapse movie and a second stream of images were sent back to the Snowgrass server for display within a dedicated page for the customer and later, the public.
In additon to the webcam/time-lapse service, our camera drone was used to test new camera locations as the surrounding buidlings were removed and for producing short videos for display on their Facebook page.

Network of remote cameras to monitor and record Genesis Energy's lining of the Tekapo canal

Lining of Tekapo canal

In 2012, Genesis Energy began the substantial project of remediating the Tekapo canal that delivers the water from Lake Tekapo between the Tekapo A and B power stations.
The work involved draining the canal and preparing and lining sections of the canal with a waterproof liner.
A culvert that allowed a natural stream to pass under the canal, was also rebuilt as part of the project.

Snowgrass Solutions was asked to install a number of their rental cameras along the canal with the purpose of recording the process.
In addition to recording the project with high resolution images, Snowgrass installed a high powered wireless network to interconnect the cameras with one of their 3G Internet connections. The 3G connection allowed the cameras to provide an additional service of uploading 720HD resolution images to a secure web page, also provided by Snowgrass. The web page allowed off-site engineers, many of them overseas, to monitor the project and was also used to display smaller resolution time lapse movies created from the images captured by the cameras.

The entire system was operated remotely. The cameras, wireless hardware and 3G Internet connection, all operated autonomously on solar power and were distributed over a 6km section of the canal. This allowed Snowgrass to provide the entire service without having to liaise with other IT teams, etc.

At the completion of each stage, the images and a series of time-lapse movies created from the images were provided to Genesis Energy and their contractors for reviewing the progress of the project.

HD (1920x1080) PTZ camera above the Franz Josef Glacier

Franz Josef webcam

Snowgrass Solutions was approached by the Department of Conservation about installing a camera at the top of a cliff overlooking the Franz Josef Glacier.
The remote camera was to be a joint venture between the Department of Conservation (DoC) and Franz Josef Glacier Guides (FJGG).
The camera was required to perform the role of a live webcam, capturing multiple views of the glacier and Waiho River, as well as record a series of images of the glacier for monitoring the glacier and for creating a time lapse movie of the glacier's behaviour. DoC and FJGG also had to be able to take control of the camera to make real time observations of the glacier and Waiho River.

Helicopter slings load into camera siteThe isolated location of the camera required the installation of a wireless network into the Waiho Valley, comprising a high altitude repeater station with views of both the Franz Josef village and the camera site. The wireless system provided network access to the camera suitable for streaming live video, but also provided Internet access in the vicinity of the glacier, and has since allowed scientists to place instruments on and around the glacier and monitor them remotely over the Internet.

In addition to being installed in a region where the annual rainfall is measured in metres, another major consideration for the project was Kea, New Zealand's inquisitive and destructive mountain parrot. Their sharp beaks can strip cables, tear plastics and they can generally cause havoc with technology at high altitude.
Snowgrass Solutions designed a solid steel mount for the camera and electronics that ensured no cabling was exposed to Kea.
Any surface large enough for a Kea to land on was interrupted with long plastic rods to prevent such landings from occurring, providing additional protection to the camera and equipment on the structure.

Access to both the camera and wireless repeater sites was by helicopter. The equipment was delivered to each site underneath the helicopter and final assembly was made on site.

Having installed a PTZ web cam for Ohau Snow Fields several years ago (see details below), Snowgrass Solutions was approached about upgrading to a new HD camera. The camera chosen was a full HD camera with a resolution of 1920 x 1080 pixels. The same resolution as an HD TV transmission.
The HD camera was installed in the same location as the original camera, near the top of mountain and the original camera was relocated down to the snow field's facilities.
The combination of the high resolution and 20x optical zoom allows the field's management to zoom in on areas of the field with exceptional detail.
Snowgrass Solutions programmed the camera to perform an autonomous web cam role by sequencing through a series of views and uploading the resulting images to the Ohau web site.
The plan for the camera is to add a network video decoder at the accommodation lodge at the bottom of the mountain. This will allow the camera's live video feed to be 'extracted' from the snow field/lodge's IP network and displayed on a large HD TV/monitor.

Two of the three 5MP cameras located on buildings surrounding the Christ Church Cathedral

With much of central Christchurch cordoned off following the February earthquake of 2011, Snowgrass Solutions was approached and asked to provide a number of 5 mega-pixel cameras for monitoring/recording the Christ Church Cathedral.
The cameras perform several roles, including the recording of images for the production of time lapse movies. The cameras also provide a simple "webcam" role by uploading regular images to a secure web page for viewing by the customer.
The cameras operate on an autonomous network within the cordon, with one camera site acting as a master with a Snowgrass developed 3G cellular router and wireless access point. The 3G router provides secure access to the Internet for both incoming and outgoing data. The other cameras connect back to the master site via the wireless network.
One camera site has no access to mains power, so operates on a solar derived power source, also included provided by Snowgrass Solutions.
Snowgrass Solutions regularly connects remotely to the camera network to download the camera's time lapse images, reducing on-going costs by reducing the number of physical visits to the cameras.
Due to the cameras being located within a demolition zone, occasional visits are still required to clean the cameras, ensuring quality images, a service also provided by Snowgrass Solutions.

HD web camera for Popua Solar Farm in Tonga

Lake Wanaka water front

In 2011 Meridian Energy contacted Snowgrass Solutions regarding the supply and installation of a web cam at one of their projects in the Pacific Island kingdom of Tonga.

"The Popua Solar Farm will be a 1 megawatt photovoltaic solar farm and the first grid-connected renewable energy generation facility in Tonga."

Snowgrass Solutions installed a very high definition, 5 megapixel network camera with the role of sending 1280 x 720 pixel images back to Snowgrass' server at 10 minute intervals, for the creation of a time lapse movie of the project.

The camera can also be polled over the Internet for a full resolution, 5MP image, allowing NZ based project managers to view aspects of the project in greater detail.

The project is an alliance between Tonga Power Ltd, the Government of Tonga and renewable energy developer Meridian Energy, with the support of the New Zealand Ministry of Foreign Affairs & Trade.

HD PTZ camera for Christchurch City

Christchurch City as viewed by the SHF HD webcam

SHF Petroleum is a family owned and operated company that provides a fuel and petroleum product delivery service in the Canterbury and South Canterbury areas.
They contacted Snowgrass Solutions regarding the installation of a camera at a high site they had access to on the Port Hills.
Various camera options were considered, but once the management team at SHF saw the picture quality of the Axis 5534-E HD PTZ camera, they made an easy decision.
The Pan-Tilt-Zoom (PTZ) camera autonomously looks at multiple views around Christchurch and uploads the HD 1280 x 720 pixel images on to their server.
Visitors to their site can see medium sized images from the camera on the web-cam page, but when clicked upon, the images open in clear HD quality. The images are larger than some smaller laptop screens.
Camera has since been removed.

PTZ camera for the Globe Progress gold mine in Reefton

Globe Progess Mine near ReeftonLocated on the west coast of New Zealand’s South Island, the Globe Progress is an opencast gold mine that operates seven days a week. The mine is subject to challenging temperature and precipitation conditions. Annual rainfall is 2,100mm. While snowfalls are regular during the winter, summer temperatures can reach around 35 degrees centigrade.
Ore zones are only mined during daylight when on-the-spot visual checking is possible.
The Alliance team of Oceana Gold and Stracon Mining wanted to find a way to ensure the pit operations were as efficient as they could be, in particular the deployment of the haul trucks throughout the mine.
They identified the potential that a rugged surveillance camera solution could have in helping achieve this, and approached Snowgrass Solutions to help investigate this option.

Given the challenging weather conditions of the area and rugged environment associated with gold mines, the camera system would have to ensure protection from the elements and particularly from moisture creep within the camera itself, which would lead to fogging.
Furthermore, the camera would have to be portable - as the mine advances, the camera would have to be relocated.
The locations of the camera would not have access to conventional power sources, so a solar charged battery system with the capacity to keep the camera operating for approximately one week without direct sunshine, was required. A high speed radio link would connect the camera to the mine’s computer network. Image quality would also be important, with the camera having to be capable of zooming from one end of the 1200m long pit to the other.

Solar powered camera assembly in use at the Globe Progress mineSnowgrass Solutions designed a wireless network solution with a long range data radio link and solar derived power system, based on the AXIS 213 PTZ Network Camera, which was chosen for its proven reliability in several of Snowgrass Solution’s previous installations and its ability to operate well on a solar charged battery system.
The camera system was configured to allow the camera to autonomously move through preset views, capturing images for an FTP upload to a remote server. These images will be used to produce a time lapse movie of the long term changes at the mine.

The camera orientation is controlled by the desktop in the Supervisor’s office while eight remote logins have also been set up so that a number of staff can access the camera and manage it remotely, if necessary.

Efficiency was the main driver for implementing the camera system and since its introduction in early August 2010 the solution has already identified deployment methods that are improving the effectiveness of mine operations. The camera enables operations supervisors to see if a project is running as it should and whether the allocation of resources is optimised. For example, the camera can identify if there are multiple trucks being loaded by a digger in one area of the pit, while another digger in different section may have no trucks to load, and quickly balance their deployment.
The IP camera system has proved its worth in other ways as well. With the installation of the large screen outside the Supervisor’s office streaming live video of the site, it increases everyone’s awareness of the pit. When each shift comes into work they can see what is happening in the mine, where the machinery is, which areas are being worked on and get an idea of the status of operations.

This project was featured in an article by Axis, the camera's manufacturer.

Internet and telephone over long range radio link

Radio link installation

Snowgrass Solutions was contacted regarding the possiblity of delivering an Internet connection and telephone line into a remote, solar powered cottage in the foothills of the Mackenzie Country.
The nearest Internet connection was in a village 14km away, but that village was visible from a hill above the cottage.

A long range radio link operating at around 24Mbits/sec was installed between a broadband connection at the village and the hill above the cottage. Power and data for the radio on the hill above the cottage was provided through cable laid in a 90 metre trench from the cottage. An Internet connection and VoIP (Voice over Internet Protocol) telephone system was installed at the cottage. The system was monitored for several months following installation and continued to operate through all weathers, including heavy snow.

PTZ webcam for Roundhill Ski Field - Lake Tekapo

Roundhill PTZ webcamRoundhill Ski Field is set into the base of the Richmond Range, overlooking Lake Tekapo. They first approached Snowgrass Solutions in 2008 regarding the possibility of installing a sophisticated webcam near the top of the ski field, where the views were the best.
In 2010 such a system was budgeted for and the system was designed and installed prior to the 2010 ski season.

The camera is an Axis 213PTZ camera operating on a solar charged battery. The camera is loaded with customised code that instructs the camera to autonomously capture a series of images at a resolution of 704 x 576 and upload them to the Roundhill website.

The camera's enclosure includes a fan forced heater to clear any ice that may be blown on to the dome. The heater is operated by the camera's operating system and activates automatically for 20 minutes twice a day, but can also be triggered manually by a remote connection to the camera.

The connection to Roundhill's web server is through a high speed 900MHz 3G mobile connection. The 3G router was developed by Snowgrass Solutions and has an external antenna for increased signal strength in remote areas. In addition to supporting remote camera connections, the router can also be used to connect any remote computer user to the Internet. With an optional wireless module, the router can share a mobile broadband connection with multiple users.

This installation is refered to on Axis, the camera manufacturer's website.

PTZ webcam for Canterbury's new Pegasus Town

PTZ camera mounted on very top of suspension bridge at Pegasus Town in CanterburyPegasus Town, north of Christchurch, is an exciting project involving the building of an entirely new town, complete with lake and golf course, on the Pegasus Bay coast.
We were approached by the developers and asked to investigate installing a webcam in the centre of the town.
A location on the top of a suspension bridge over the lake was selected and an Axis PTZ was chosen as the prefered camera due to its ability to capture multiple views from a single vantage point.

The camera uses a medium range radio data link to the nearest network with an Internet gateway.
The camera captures a series of images every 15 minutes during daylight hours.

Low voltage airport runway lighting system

LED runway lighting system in use

LED runway lightSeveral years ago we were contacted by a well established aviation company with regard to designing and installing a runway lighting system for their rural airport.

There were several considerations in designing the system.
The rocky terrain would not allow cables to be buried more than several hundred millimetres blow the surface.
The air field was located in an area of light sensitivity, requiring minimal vertical light emissions.

Because of the rocky terrain, a low voltage system was required, as the deep trenching required of a high voltage system, was not possible.
An LED system was chosen and made possible through recent developments in LED (light emitting diode) technology.
The LED's chosen were "night sky friendly" with only 4% of all light emissions emitted vertically.
80% of the light emitted is at 3 degrees above horizontal, the typical glide slope for an aircraft approach to a runway.Runway light installation

 

 

Several essential components were imported and aluminium components were designed by Snowgrass Solutions and manufactured locally.
An energy efficient system was manufactured to provide operation on a power supply of just 32v over a cable length of approximately 2 kilometres.

A system of 23 lights was installed at the airport, comprising of 21 white and 2 red LED lights, one at each end of the runway.

Completed, the entire runway lighting system requires only 80 watts of electrical power to operate. Less power than is required to operate a single incandescent lamp used in a domestic house, but with a horizontal night time visibility of approximately 15km.

Ohau Snow Field webcam and high endurance 230v UPS systems

Ohau webcam installationAs part of a major upgrade to Ohau Snow Field in 2008, Snowgrass Solutions installed a P-T-Z webcam with spectacular views from the upper regions of the mountain.
The camera will be used to capture several views from its location and send them as images to the Ohau web-server, for display on their new webcam page.

The camera is loaded with customised scripts that instruct the camera to autonomously steer through multiple views and upload the resulting series of images to a website via FTP upload.

Ohau Ski Field network and 24 hour UPS equipment

 

 


 

The ski field's 230v power is derived from diesel generation. The camera and its associated network equipment, radio link and the climate monitoring for the field's new snow making system, had to continue operating on 230v for around 24 hours when the generator was shut down.
An 800VA pure sine-wave UPS system was installed along with a high capacity AGM battery to meet the requirement in such a severe climate.
A second UPS was also installed at the generator facility to maintain a second radio link and the generator and snow making auto-start equipment, allowing both systems to be started remotely over the network.

 

Typical alpine conditions the camera must endure

Alpine weather conditions at Ohau required substantial modification to the camera's enclosure to assist in rapidly clearing ice and snow from the camera's dome.


To maintain battery endurance, the resulting heating system only operates when the field's diesel generator is running, usually only when the field is open.

 

This camera has since been upgraded to an HD camera. See info above.

Lake Wanaka Tourism webcams

 

Wanaka interactive webcamTo improve the quality of the original Wanaka webcam, Snowgrass Solutions were contacted by Lake Wanaka Tourism to recommend and supply a high quality fixed webcam to provide high resolution images for the Lake Wanaka Tourism website.
A P-T-Z live video camera has since been installed in a semi-remote location, part way up Lake Wanaka. The installation included a high speed radio data link back to the Lake Wanaka village.
Because the camera was mounted on a picturesque private homestead, a purpose built mount was designed, constructed and professionally coloured to lessen the visual impact of mounting the camera on the roof.
This camera will complement the existing fixed camera by providing live video and the ability to remotely control the camera via their website.

Fishing fleet communications network

Pegasus Fishing vesselWith the demise of Telecom NZ's analogue 025 network and the forecast demise of their current CDMA digital network, A Lyttelton based fishing company required reliable company communications in the harsh and remote environment off the South Island's East Coast.
Snowgrass Solutions supplied an advanced Tait Mobile Radio solution operating through a network of high altitude coastal repeater stations. This provided reliable communications from vessel to shore and vessel to vessel.
The coverage of the network selected by Snowgrass Solution has marine voice and data coverage superior to cellular on the South Island's East Coast and operates around the vast majority of New Zealand's coastline.


Tait mobile radios with vessel tracking module installed

Vessel safety was also taken into consideration with the addition of GPS tracking to enable shore based management to track the vessels and their daily history. GPS position data is stored on a small data logger on the vessel and intermittently transmitted over the same coastal network used to provide the voice communications.
The management at the company is able to log on to a secure Internet based server to view the vessel's position on a map of New Zealand and to view the vessel's track history.
Snowgrass Solutions is currently working with the manufacturer and operator of the tracking service to add more specific maritime features such as bathymetric marine charts and the ability to monitor the fuel management systems on the vessels.

Mt Dobson webcam

Mt Dobson webcamAs part of providing visitors to the Mount Dobson website with a true representation of the current snow conditions, an Axis 221 day/night camera was supplied to upload large 640x480 pixel images to the Mount Dobson website.
In addition to the image uploads, the camera can be viewed in password-protected live video mode by management in nearby Fairlie. Using their network connection with the mountain, video mode allows them to better gauge wind speeds and snow fall to make more informed decisions on whether to open the ski area or not.
In low-light conditions the Axis 211 camera automatically changes to night mode by bringing an infrared filter into the sensor path, bringing the light sensitivity down to 0.08lux.

Snowgrass Solutions did not install this camera. It was self installed by Mt Dobson.

Tekapo Tourism webcam

The Tekapo Tourism webcam after a fall of snowTo help provide a superior Tekapo experience, Tekapo Tourism Ltd wanted to provide visitors to their website with up to the minute information about what it was really like in Tekapo.

 

To achieve this, an Axis 213PTZ (Pan Tilt Zoom) camera was installed on the summit of a nearby mountain and using a high speed radio data link over 3 kilometres to the village, the camera connects directly to a broadband connection for access.
While night capable, the camera is not used in IR (black and white) mode

 

 

The camera operates in two modes.

FTP image upload. The camera uploads regularly updated images of the surrounding area to the Tekapo Tourism website. The views are updated whenever the camera looks in a particular direction.

 > Click to view page

Live video mode. In addition to uploading still images, the camera also provides visitors to the site with live 1 frame per second video. Visitors have a list of twenty views from which they can click on. Once a view is selected the camera will pan, tilt and zoom to a preset view memorised into the camera.
The camera's 26x lens can zoom in on even the most distant objects.
To keep broadband data costs managable, video sessions last 90 seconds and can be restarted by reloading the page.

 > Click to view page

 > Click to view the homepage

The camera has also been used to create a time lapse movie of the conditions in Tekapo over seven months.
Because the camera is a PTZ, the method of capturing the images did not result in a uniform capture interval, but still gives a good indication of how the climate in the area changed over the period.
