With my older Orion system, I still need to use an SD card for firmware updates and you also need to go to the camera to change routing. I told BEC that these were weaknesses. Sounds like they are fixed in the new X-series cams you guys are using. I only have one X-series cam for testing. The only weakness I've found is that the radio is not as strong and transmission distances are much shorter. I have a very challenging RF environment on a pine farm, so I have elevated towers with big antennas on my system. The big upside of the new X-series is the lower cost and the fact that they went to a 12-volt system which makes solar much easier.
My cams are in the woods. Will solar help much in the woods?
Solar requires sun. How much depends on many factors. All of these cams still use old SLA batteries. These are subject to sulfation. Sulfation occurs when a battery is deprived of a full charge, it builds up and remains on battery plates. When too much sulfation occurs, it can impede the chemical to electrical conversion and greatly impact battery performance. It shortens the life-span significantly. If the charge level drops below the 70% level and stays there for long, I've found the lifespan of the battery shortens significantly.
You can think of the battery as a buffer. It need to be large enough to sustain the system during times when the amount of power consumed is less than the amount of power being fed into the system. So, ideally I would like a battery large enough to handle cloudy stormy days to match my weather without dropping below 70% charge.
The solar panel is the power source. The amount of power produced depends on the size and efficiency of the panel and the amount of sun it receives. So, a large efficient panel needs fewer hours of lower intensity sun to produce the same amount of energy as a smaller less efficient panel.
The camera is the power consumer. Most of the consumption is in RF transmission, and the second is the flash. The rest of the camera operation draws very litte power. So, the amount of power consumed is driven by the camera placement and programming. If you set them to take a burst of high resolution pictures and reset quickly in high traffic areas and/or make them routers for pictures from other cameras, they will consume a lot of power quickly. Your signal strength plays an important role too. When signal strength is weak, packets get dropped and need to be retransmitted.
Most of my camera are in small openings and placed where the panels get good sun. I have one camera that is in the hardwoods. It gets lost of traffic in the fall when there are acorns but light traffic most of the year. All of my cameras are set on the highest resolution so I can zoom in and identify individual bucks. Because I use them primarily for longitudinal population trend monitoring, every camera is set with the same 5 minute delay between pics. I had to change the battery too frequently for this camera. I eventually hinged some trees. Because of the situation, I could only get a few hours of morning sun when it is low intensity. I ended up using a 30 amp hour external battery and a large 60 watt solar panel and an PMW controller. This was enough to balance the power flow for that camera. In the winter when there are no leave on the trees, it is overkill, but in the summer, the panel is large enough that the morning sun is enough to keep the battery easily topped of for the limited number of pics I get from the camera. During the fall, when the picture load increases it is enough to keep it going until the leaves fall. I have a 9 db antenna on it to keep the signal levels up.
I have similar setups on my major routing cameras. The are in open areas that get full sun, but they route pictures from many other cameras.
If the FCC makes the decision to license out the 900 MHZ spectrum you could be in for some trouble. There is a company pushing them to do just that.
I doubt this will happen. There are many many commercial devices that use this spectrum because it is unlicensed.
