Recently I was asked to put together a system to automatically take photos of dogs as they jumped over a small hedge and then could be be easily uploaded to Pedigree’s We’re For Dogs Facebook page.
Safety was my main concern for both the dogs and us humans involved in the affair. Traditionally race line finishes which take photographs use lasers. This is normally fine as the chances of a laser hitting an eye, human or animal is very small due to the positioning height of such devices in relation to the things passing them being relatively constant. Dogs, just like humans come in all shapes and sizes, which leads to uncertainty when positioning possibly eye damaging lasers. To get around this I opted for and Infra Red trigging system. After trawling the internet for a ready made system I came across on made by Cognisys in the US. The Range IR is a clever devise as it is a self contained unit firing out a harmless beam of IR which can be varied in length as desired. When the beam is broken the sensor sends a signal out to the camera and a photograph is taken. Quite frankly I believe its the work of magical Pixies and that’s fine with me. Continue reading
