I've been out of the market for quite a long time. Back when I first got my property, I was using the cheap ($200-$300) Chinese cams. It was a constant hassle. They had very good picture quality, but horrible quality control. Many got replaced under warranty and the replacements didn't last long. I spent more time messing with cameras than getting the data I wanted. If you just want to see what is out there and don't care about life span or missing game, most of the cameras made in China will do. If the data you collect is important, these are a poor choice.
I was looking to collect data for QDM decisions. If you have gaps in the data, it becomes hard to find trends. I did a pretty thorough analysis at the time. I came up with two companies that had good QC, good life span, and fast reliable trigger times. They were Reconyx and BuckeyeCam. I ended up choosing BuckeyeCam. At the time my Orion's came out, the company was first servicing the military and once those orders for filled, started selling them to consumers. That meant the design was very well tested and went through shock and vibe. All of the electronics were coated. Even if you get a good Chinese cam off the line, the lifespan is short. The reason is that you need to change batteries so the camera can't be sealed. Any moisture that gets in through the battery compartment vaporizes when the sun heats up the camera and it then condenses when it cools down at night. Without coated electronics, eventually you get corrosion. The only reason I chose BuckeyeCam over Reconyx at the time was they BEC had wireless (well before cell cams).
My cameras have very old, but well proven, technology. The picture quality is "good enough" for my purposes. The reliability is top notch. With solar panels, my Orions run for well over a year with no attention and the pics are sent back to my camp.
These cameras were NOT cheap, but were a perfect fit for my application. I certainly would not choose these cameras for use in a high theft environment. My point is, the best fit camera for you will really depend on your application. It all boils down to trading off characteristics. There is no "best" camera out there. They don't make Orions any more. I bought my last group used from John on this site. I bought them for backup because at some point, one of my dozen orions on the farm is bound to have a failure. None of mine have failed yet and they have been running for many years, but everything fails eventually. The current BuckeyeCam is the X80. I bought one of those to experiment with as a future alternative when the Orion network eventually fails. I like it just as well as the Orions. It is much smaller and 12-volt with somewhat newer technology.
Thanks,
