In today ’s populace , modern television camera technology is used in so many ways , from taking snaps during a poolside vacation to surveying the grounds of a vital commercial enterprise . Despite these important uses , not all television camera are made the same , and some are not as weather - resilient as others .
Although there are many utmost atmospheric condition that affect the carrying out of certificate television camera , Methedrine is known to be peculiarly troublesome . It can enfeeble batteries while also obscuring the image .
Axis Communicationsis a web technology and industry leader that offers solutions in video surveillance , access control condition , intercom , and audio system . They determine to push the boundaries of their applied science in a harsh environment by make an strange experiment to try it in the extreme . They went to Ulricehamns Ishall in Sweden to film an ice hockey game match from a seemingly “ insufferable ” angle – inside the deoxyephedrine .

Ice hockeyis a tight - paced , thrilling sport that is one of the most democratic wintertime sports in the public . It is a game between two squad who jade skates and play on an glass skating rink ; the aim is to motivate a rubber disk ( called the puck ) past the goal line that is guarded by a goalie .
Translating the excitement to a blind for at - dwelling house - viewer stand for that footage need to come in from all angles , but is it really possible to film it from inside the ice ?
There were some logistic challenge to this experimentation . first of all , the tv camera itself would have to be workable after being encased in ice . Secondly , the ice in an ice skating rink is less than 40 millimeter ( 1.6 inches ) heavyset , so the camera would have to fit into that space . Thirdly , the ice had to be readable enough so that the photographic camera could shoot the striking footage .
The camera selection
The experimental setup included a sensor and a main unit with audio . The television camera that was chosen wasAXIS F2135 - REFisheye Sensor . This was a full high - definition sensor that had 60 systema skeletale per second at 1080p and could record in color and sound recording . It also supply a 185 ° horizontal field perspective and a rugged sensor unit . Outside the experiment setup , this sensor can be installed practically anywhere ( inside and out of doors ) and is able to defy quivering and temperatures as low-pitched as -40 ° C ( -40 ° F ) and as high as 60 ° C ( 140 ° F ) .
For the main unit of measurement , AXIS F9114was used . This had a rugged design and connection , along with multiple sensor and cable options .
The set up
The team take the tv camera and mounted it horizontally within the methamphetamine , due to the special space . A custom 3D - impress gigue was made to house the television camera . A mirror was rank at a 45 ° slant so the camera could record the above action . Then the whole organization was frozen in the methamphetamine hydrochloride .
“ The big challenge with this project has been the prison term restraint combine with getting vindicated ice , ” Niklas Hansson , expert concept developing technologist of the task , say in a video sent to IFLScience . “ The combination of the two has made it very hard to cycle and experimentation with the different water ice setups we ’ve been doing where it actually takes time to make a liter of shabu freeze . ”
The sensing element had to be optimized to take into account the ice refraction and other impurity . Icerefractionis 1.44 - 2.50 μm , which is the measurement of the bending of a beam of sparkle when passing through unlike mediums . Changes to the index can influence the size and place of an image taken by a lens .
To optimize the frame-up , the mental faculty had to be immobilize and defrosted multiple times to ensure that the relevant pinch work out .
“ We were not indisputable that it would be honorable simulacrum quality . We had to test it out . The piddle could contain different particles . There could be air bubble , cracks in the frappe . And then there is the surface of the methamphetamine itself , ” said Hansson . “ That would affect how the prototype would be . So , we had to do multiple tests to ensure that we get a good effigy quality . ”
Once the optimization was complete , the faculty setup was freeze at the Axis Communications facilities .
Inserting into the ice rink
You might think it would be gentle to position the photographic camera within the ice , but this is not as straightforward as it seems .
An ice hockey rink is firstly made up of a concrete slab that has a chill element in it . Then the ice is built up layer - by - level ( close to an inch and a half ) . For this experiment , a hole had to be create so they could inclose the ready - made puck - shaped photographic camera rig . Once introduce , a Zamboni was driven back and forth to freeze it into place .
The result
The resultant were clear footage of the Methedrine field hockey match from a perspective few but the puck have fancy .

Overall , the experiment was a succeeder . The detector recorded the ice hockey match through the water ice and were able to show exciting footage .
“ It ’s a proof of our quality in the pattern and the build on the television camera . They are try out for vast temperature mountain chain , both from the very cold to the very hot . So , this is proof that it actually work in practice as well , ” Hansson submit .
