Hi Hans, nice to hear from you and thanks for your advice.
Yes, I must take a some pictures. That wouldn’t be worthwhile just yet though, as I’m having to change how some of the cameras are mounted and the re-installation’s still very much a work in progress. I’m hoping that I’ve successfully uploaded a video with images from my first set-up that will illustrate why that’s been necessary: a wavy effect in the two lower images (both cameras rubber-mounted), and vibration in a specific band of revs of the plate steel bracket carrying the camera down by the front wheel. The only one of the four cameras to give a rock-steady image is the rear-facing one bolted to one of the luggage rack mounts. That suggests to me that I should mount all of the cameras as firmly as possible (the Fazer’s engine is very smooth), which is what I’m currently trying to achieve. The issue with resonance of the bracket supporting the camera down by the front wheel I’m going to attempt to solve by damping it with some form of restraint under tension, or possibly by adding some weight to it. BTW, the image from this camera is cropped because I’ve cobbled an acrylic cover to protect the lens against stone chips, whose opaque edge limits the field of view a bit.
As a compromise between image quality and recording time before looping commences I’ve set all four cameras to 1920 x 1080, though the quality of this video must be far below that because I’ve had to compress it below 50MB in order to be able to upload it. It’s not very obvious in the video because of the low speeds involved, but, inevitably, wind noise was initially an issue. I’ve managed to significantly reduce its effect by recording at volume setting 1, and tying a soft braided cord, similar to a shoelace, over the microphone aperture in the dvr/camera 🙂.
