A small upgrade in order to capture the wildlife walking down my fenceline. The post is 10' tall and the camera arm will hang over the fence, giving me a wide angle (2MP) and a telephoto (4MP) view both north and south. There's a 40A junction box feeding an unused, heated stock waterer at the corral, ~400' from the nearest AP. After adding a 2A in-line fuse, power gets fed to a ZyXel GS1900-8HP fanless PoE switch, which in turn feeds the 4 cams and a EnGenius ECB600 set to client bridge mode with a 16db panel antenna. Everything was bench configured, tested and incorporated into the twin iSpy instances, so everything worked as expected upon installation. But I discovered my existing AP is failing... It's an older dual-band EnGenius EOR7550 set as AP on 2.4 and CB on 5GHz. The 5G was acting up a few days ago so I patched the AP into a switch hard wired back to a Brocade ICX6450 until I could diagnose the issue. The issue became apparent once I powered up the new remote cams: -80db signal. After testing, the old EnGenius AP is not broadcasting or receiving on its external antenna, only its internal, which is on the wrong side of the shop... So I'm limping along using 2 of 4 cams and trying not to kill the connection while looking at a replacement EOR7550 on ebay: only $15USD, but with shipping/ duty that translates to $90 or more Canuckinan pesos. It's time to consider an upgrade... I have several EnGenius wireless devices and really like them; the only failure to date has been the p/s on a 5GHz AP. But they are all old. Can anyone comment on the Ruckus or Cisco wireless systems suitable for a 'campus' of 10 acres? (Expandable to encompass our entire 80 acres via solar charged lithium batteries and the same PoE switch/ AP/ cams. They're on the drawing board, although at our latitude I need >200W of charging capacity per site). Random criteria: The failed EOR7550 has N-connectors for both 2.4 and 5, and I need to keep these external antennas in place, as they're attached to the yard light atop the shop. License should be not required, free, freely available or dirt cheap. I'd like to step up in class, so UBNT may or may not be an option; they make some good stuff along with the junk.
