I read about adding a second PW-001 battery in another post. If needed, its $20, so a viable is option if the solar can't keep up. I am going to see how the solar works on my 12AA J-series cameras mounted in transition points during deer season and into winter. Hopefully the solar will be a big help.
Here is my follow-up, given I now have one year on both the Cuddeback solar system and the SpyPoint solar system.
1) Cuddeback Cuddelink System
A) The discontinued J-series cameras with solar are working great...the Cuddeback system has been pretty much maintenance free, and both the 12AA (early version using rechargables) and 4D (later version) with PW3600 solar panels worked fine all winter. All J-cameras are in partial shade in the woods.
B) The G-series home cell camera is in full sun, and has not been touched in a year.
C) Summary: No issues over the past year on my five camera setup. I believe this would be a solid candidate for a remote property as a stand-alone or with the cuddelink system. Cost is moderate, with about $1800 invested in this system (cameras, solar, batteries, cards) plus the $120/year fee. In peak picture season I will likely need to upgrade the subscription to more than 2500 photos.
2) SpyPoint: I am running a six camera SpyPoint setup, three Solar Link-Micros, two Link-Micros and one Flex. Their program allows 100 pictures per month free, which is what I have done for the past year. I just discovered the "insider club" cost only $99.00/year ups this to 250
per camera, not just one camera, so I get 1500/pictures per month for $8. Great bang for the buck, and the solar cameras have kept running all year. One is in a shaded area, and went down to 50% last spring, but never quite working. All are at 100% and functioning great. The total cost for this system has been $600 (cameras [built in solar], batteries [for the non-solar, the solar come with LiOn batteries], cards) plus $100 for the one year insider club upgrade. All cameras link to a common app, so you can see all of the pictures from each camera without separate log-ins.
Since, like you, I have some remote properties, I am going to recommend the SpyPoint solar as the most cost-effective option. This summer the Flex Solar is coming out, which provides video, solar, and works on any network.
For a property with a network, or if you want to ensure you have "higher quality" cameras, I would recommend the new Cuddeback L series. You can feel the difference in quality, and having John on this forum to help answer questions is priceless.
