Ubiquiti PBE-5AC-620 PowerBeam AC High-Performance airMAX Bridge Review: Great device - This product pbe5ac-620, an amazing product from ubiquity. I got what i want. I installed 25 cctv cameras of full HD at a distance of 24.5 km from my residence. One device intalled at the site where cameras installed and the other one at the residence. Not a single issue was experienced while monitoring all the cameras remotely. With 20mhz, i got throughput of 90/100 mbps. It was beyond my expectation.Overall, this is user-friendly device. I will always recommend for the new buyers to buy without any hesitation and also suugest to used airlink to get the right device depending on the distance between two points.
