LINOVISIONIndustrial 5 Ports Gigabit Solar POE Switch with DC9V-54V to DC48V Voltage Booster,4 x IEEE802.3af/at 30W POE Ports @120W, IP40, Compact POE Power for Solar Power/RV Truck/VoIP Systems

must have for 12v systems! got this to take advantage of my lithium batteries in my truck camper. works great!

These switches are really nice. Very small and can witstand high temperatures. I use them for nema enclosures that get extremely hot. It only needs 12volts and powers (4) 48volt IP cameras. I have bought 10 of these so far. Highly recommend.

This switch worked exactly the way it was advertised, we used a simple 12v DC adaptor to power the unit. We connect more than one IP camera to the switch with no problem. We will be purchasing more of these.

I've run 3 of these for over a year, and I can say they just work. From cold winters to the Texas summer, I have had zero issues with these protected only by a basic waterproof enclosure. If you're looking for a good 12v POE injector for use with a solar project, you will not be disappointed.

While a bit expensive for what it does, it is a high quality product and runs on 12-24VDC. Excellent for putting in an outdoor enclosure.

I have used this switch multiple times for solar powered camera setups. Works great for powering PoE cameras from a 12v battery. Runs quite hot but have never had an issue in 2 years.

Needed to power an antenna, two cameras and a wifi access point at a remote site. 12volt battery and 100w solar panel and I was in business. Great product Linovision!

This powered 3 Poe cams with IR (approx 13w) on at night for 1+ day on a 12v 100ah deepcell battery, we are very pleased with the performance and how cool it runs , haven't used it on Poe+ as we don't have 24v to it yet, but will update after we do.
