Kosin store outdoor sound systems

The mono internal microphone is severely limiting in producing reasonable quality audio recordings. It provides only 1 channel, is sensitive to camera handling and wind noise when used outdoors. I wanted to find a cost effective solution to use with the camera when I needed to get better quality, noise free, stereo sound when using the camera both indoors and outside. Without going to the expensive of buying something like the Rode video mike which really makes the camera very prominent whilst trying to be discrete with filming I set about experimenting with less expensive electret microphones and capsules to see what the quality would be like with the 550D/60D. The 3.5mm stereo input jack of the camera also provides power for external electret mikes so this came as a real bonus as cheap capsules could be used without the need for them to have their own power source and electronics. Surprisingly the stereo tie clip microphone ( available of ebay from several retailers) gave good frequency response and sensitivity without excessive background noise. I am no audiophile and my hearing upper limit is decreasing but for general purpose recording this unit IMHO provides good enough stereo signals for most purposes that i need it for. It is easy to add a "dead cat" type fur windshield for outside use and can be attched to the hot shoe of the camera by means of a plastic adaptor which can easily be made by anyone with a few DIY skills.

This video was made in response to a request we got from an enforcement agency looking to monitor illegal activity from remote locations. They had managed to secure local property owner's permission to install a cctv system but were concerned the cctv cameras they currently used were too large, to the point where some owners were refusing permission. We came up with two solutions, both low cost within their product groups: We suggested a low cost PTZ cctv camera which could be controlled from the agency's office using an internet connection and the virtual control panel of our DVR recorder. This featured a powerful 10 times optical zoom lens. We also suggested a low cost, almost throw away solution using a modified version of our B5 series standard body day / night cctv camera with a 9-22mm manual zoom lens. Both cameras were specified without infra red illumination (hence the modification of the B5 series camera). This is because number plate identification was important in obtaining a prosecution and the infra red illumination tends to glare out UK number plates which are highly reflective.
