I went searching for some stats on the Vivitar camera, couldn't find any of 8 or 9 web pages. Doesn't say anything about battery capacity, or memory, very important! But for 40 bucks you can't expect much.
I've used 4 or 5 different cameras on my bikes. Currently using a GoPro Hero 1080p Hi Def. I've run power to it, so I don't have to worry about battery life, and have a 32 gig SD card in it. I can record for just about 4 hours before maxing the SD card. On batteries it is good for about 2 hours. Do you need Hi Def? YES!
The Vivitar says about 1.3 megapixil. If you try to blow up that great still you took, or freeze frame a video it will get very grainy much larger than 3X5 Hi Def is about 8 megapixil!
Here is about 4 minutes of a 2 hour ride through Simi Valley. Shot with the GoPRo and edited using Sony Vegas Editing software:
I know the GoPro is kind of pricey, but we have some great slide shows and videos we've taken of our trips. They really look great on our 16X9 format Hi Def television, kinda like going there again! Remember, the stuff on Youtube is condensed way down for downloading!
Good Luck and happy hunting!
And, here is a picture of my bike with the camera mounted just above the faring.
