Productbeschrijving
vhfBridge is ontworpen om VHF-zenders van derden aan te sluiten om een extra kanaal te creëren voor het verzenden van gebeurtenissen naar het CMS.
Het communicatiekanaal met het CMS dat is aangemaakt met vhfBridge kan worden gebruikt als het enige kanaal of als back-upkanaal voor communicatie met het CMS (aanbevolen, betrouwbaardere optie). Dit betekent dat de hub tegelijkertijd alle gebeurtenissen en alarmen naar de meldkamer van het beveiligingsbedrijf kan verzenden, niet alleen via SIA (DC-09), ADEMCO 685, SurGard (Contact ID) en andere bedrijfseigen protocollen, maar ook via vhfBridge.
Via het Jeweller-radiokanaal ontvangt de transponder informatie over alarmen en gebeurtenissen van de hub. Vervolgens verzendt VhfBridge het via draden naar een VHF-zender van derden. De VHF-zender verzendt op zijn beurt alle gebeurtenissen en alarmen via een radiokanaal naar het CMS.

It’s a win
Size: 5X, Color: Burgundy
I like this shirt. It’s super comfortable I bought 2 sizes to big in order for it to be super loose fit and longer. I bought the red/maroon color and it’s a very nice color. It’s light weight so you aren’t so hot that it stinks. The size seems to be true to size really. It looks super good with a nice pair of leggings. Seems well made. Washes good. It’s a win

Lightweight sweater
Size: XX-Large, Color: Navy
This sweater is very soft and lightweight making it perfect for spring and fall. The colors are beautiful and match the posted images. I have bought several different colors because I like them so much. I have larger arms and the sleeves have plenty of room. They do not wrinkle easily and are holding up well with routine wear and washing. My husband accidentally washed my navy one in hot water and put it in the dryer which made it fade and shrink considerably so be careful to read the label on how to wash and dry the garment and it will be just fine:

Very nice, yet hangs
Size: XX-Large, Color: Ivory
Soft, pretty and cozy. The bright clean color of white is crisp and pure.
Unfortunately, the shoulders are too big and it hangs or is too wide and in turn, the sleeves are too long.
The rest of it is proportionally correct for my body, so a different size would not work.

Lightweight & good price for quality
Size: Medium, Color: Camel Heather
Lightweight as other reviewers noted. I purchased camel color & oatmeal heather color for travelling on long plane ride while wearing with leggings. Ribbed cuffs and hem, which I like. V neck just right on me. Cotton blend knit, good. Color as expected. Sleeves long enough (yay!) Probably will pill eventually, but I'm not worried about it at the moment. Doesn't look cheap, which is nice for inexpensive top. I don't wear leggings a lot, so I don't think these will get lots of use, so until they start looking pilly I'll use them when I need to. I'm 5'7" & weigh 115 lbs, 34 A, and 37 hip. Size small in both colors draped perfectly, looser fit style, not clingy or tight around the bum, which is what I wanted. It doesn't look baggy or boxy on me, but I'm relatively slim so it may not fit as I've described for those with bigger bustline and/or waistline measurements and/or tummy. I think it is flattering on me, so I'm keeping them. I would say the size S it runs slightly big for my body type if that helps. Everyone is different even when we wear the same size! After reading reviews I purchased S and M sizes. I returned the mediums as they'd be way to baggy on me and too big across the shoulders.

Fantastic Sweater for the Price!
Size: XX-Large, Color: Charcoal Heather, Size: XX-Large, Color: Charcoal Heather
I'll admit it, I was VERY skeptical about buying an Amazon Basics Sweater. I was sure the sizing or material or something would have to be off as the sweater was very reasonably priced. I was very happily proven wrong.
This sweater is great. It's a v-neck, the most flattering fit for me and the v is not so deep as to be indecent, I can wear it easily and comfortably to work without a camisole underneath - even as a rather busty gal. The material is nice and soft. It's not cashmere soft, but it feels much better than a $20 sweater. It also washes pretty well, I've washed my sweater a few times and have had no shrinkage. I don't tend to put sweaters in the dryer, I air dry them - so that probably helps as well. After 2 or 3 washes, there is a slight amount of pilling underneath the arms where the sweater rubs against itself, but not a large or greatly noticeable amount.
The sweater is also pretty long. I'm not sure I'd wear it as a tunic (with leggings), but I do wear it with skinny jeans comfortably and don't worry about it riding up in the back.
I found it to be true to size. It's meant to fit a little looser and I like that. It's a great comfy sweater and I get a lot of compliments on it. This is a great value for the price - I will definitely try other Amazon Essentials. I own it in three colors (and counting).
Update a year later - I just purchased 3 more of these sweaters for the upcoming winter. They are some of my absolute favorites. They are flattering even if you have a bit of tummy and not too heavy. These have withheld multiple washing with minimal beading (or whatever you call it when the little fuzzy balls appear at the high friction points). I have done some shaving on the sweater and I'm pretty fastidious about washing them on gentle and letting them air dry (like I do with most of my sweaters).
