HD web camera for Lake Wanaka Tourism

Several years ago Snowgrass Solutions installed two web cams for Lake Wanaka Tourism. A fixed camera for providing regular image updates for their web site and a PTZ camera for providing interactive views of the lake in live video.
With the advancement of new HD cameras, Snowgrass Solutions was asked to upgrade the fixed camera to a full HD (high definition) camera. The Axis P1344 1280 x 720 pixel camera has been installed and will shortly be providing 720HD images for their web site.

HD PTZ camera for Christchurch City

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.
One of the views monitored by the camera is the earthquake damaged Grand Chancellor Hotel. The building is Christchurch's tallest building and was badly damaged by the earthquakes that hit Christchurch in 2010-2011. The camera was used to capture images for creating a time lapse video of the demolition process. Because the camera was 6.3km away from the building, significant amounts of zoom were required to provide detail. The amount of zoom was greater than that used by standard binoculars. Such zoom showed up the amount of movement the building experienced when warmed by direct sunlight. While the movement was a tiny fraction of a degree, the movie appeared to suffer camera shake.

PTZ camera for the Globe Progress gold mine in Reefton

Located 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.

Snowgrass 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

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 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.

PTZ webcam for Canterbury's new Pegasus Town

Pegasus 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.

Camera for monitoring of remote construction site

An established South Island based developer approached Snowgrass Solutions regarding a camera system that would allow them to monitor remotely, a major construction project.
In addition to providing them with a live video feed of the site over a simple broadband connection, the camera was also required to capture regular high quality images of the project that could subsequently be used by their customer to create a time lapse video of the building's construction.
For this reason, an HDTV camera was installed with a resolution of 1280 x 800 pixels and capable of transmitting video over the Internet in the very economical H.264 format.

Remote, solar powered video recorder

Snowgrass Solutions was contacted by a reputable Environmental Consultancy company in Auckland, regarding the design and installation of a remote video recording system for monitoring an area of interest, where power and an Internet connection was not available.

A system was designed using a high resolution miniature camera, Digital Video Recorder (DVR), timer, solar panel and high capacity battery.
The system was configured to record up to 2 months of video during daylight hours only.

Approximately once a month the site is attended and the DVR's Hard Disk Drive (HDD) swapped. The HDD is then courier to the consultants in Auckland for review.
The observations are used as evidence to support the requirements of their customer's Resource Consent.
