I just checked and it looks like their store front is closed but their website shows all their current products. I'd try calling them. It may be related to the supply chain issues.
Just to give you a ball park, I'll tell you what I paid.
This is for their current system, not the older Orion.
Back in 2012, I bought an X7D (their first camera after Orion) for about $600 for the cam and $250 for the PC base. They then came out with an upgraded version (better radio) called the X80. They offered an upgrade to X7D customers and I bought that for another $200. That gave me the basic single camera system for a total of a little over $1K. This includes the basic rubber ducky antenna for the cam and base. I bought upgraded antennas from L-com.
This seems pretty expensive but my older BuckeyeCam Orion system has a PC base and a dozen camera. I added cameras over time. They first came out with the Apollo back around 2008 and I bought one. It is basically an Orion without a radio. I then upgraded it to an Orion and bought more cams each year. The Orion network is still up an running. The reason I bought the X80 was for testing. I figured the Orion system would eventually fail and I wanted to be ready to upgrade without losing data. I've had a few minor issues over the years with the cams and sent them back for repair, No design or fabrication issues. They have been things like connectors wearing out or lexan lens covers weathering over time. I became concerned that the technology was getting so old, it may be difficult for BEC to get parts for the Orion. Then John, (Who used to own Big Rock Trees), retired, moved, and sold me all his Buckeye Orion cams and accessories. I figured I'd uses them as spares over time. Turns out I deployed them rather than letting them sit on a shelf.
Right now, the Orion network is running just fine, so I have no near-term plans to upgrade.
My oldest Orion and PC base is 14 years old now and has been running 24/7/365 since it was deployed. When I amortize the high initial cost over the life span of the system (14 years so far) it was much less expensive than systems with lower up front cost.
Thanks,
