Hi, I ran across this discussion and decided to register to offer some insight and hopefully learn a little too. I am a co-founder of TimeLapseCameras.com we are the only Brinno Certified retailer in North America. The Brinno TLC2000 camera is a new release and we have one for evaluation. The Brinno TLC200 line of cameras are time tested, proven solutions for long term timelapse.
The BCC2000 bundle includes the TLC2000 camera, it's priced at $550 and the housing accepts up to 16 AA batteries. Due to the cost, design and other factors we will probably offer the camera on a special order only basis. However, until we complete long term testing we are still on the fence with this product.
Regardless, the Brinno TLC200 Pro (BCC200) would be a great camera for your project. You would only need to change batteries every 2 months, the cost is less, the camera is compact and it's suitable for a wide variety of projects.
We have another great camera option with long term battery life, optical zoom, wi-fi app control with full screen preview, motion detection and more. Please take a look at AfidusCam.com for details.
I am happy to answer any long term time lapse questions. Thank you! Marie
