Productbeschrijving
Dahua DHI-ARC3800H-FW2 is een draadloze alarmhub die geschikt is om de veiligheid van uw faciliteit te garanderen. Het ondersteunt maximaal 150 draadloze apparaten, waaronder 6 sirenes, 64 PIR-camera's, 64 sleutelhangers, 8 toetsenborden en 4 repeaters, waardoor u uw beveiligingssysteem flexibel kunt aanpassen aan uw behoeften.
Het apparaat is uitgerust met een 8-kanaals IPC-video-ingang, die is ontworpen om alarmen te downloaden, zodat er tijdig op eventuele incidenten kan worden gereageerd. Meldingen via sms, telefoontjes en video zijn ook inbegrepen, en een offline cache zorgt voor extra betrouwbaarheid.
De hub ondersteunt Wi-Fi 2.4G voor draadloze verbinding en heeft één RJ-45 Ethernet-poort (10/100 Mbps) voor bekabelde verbinding. Om de betrouwbaarheid en redundantie van de communicatie te vergroten, ondersteunt het apparaat de installatie van twee simkaarten.

Not cooling throughout the night
Size: Standard Size(1 Pack)
The quality of the pillow was great the stitching as well. The one side did feel cool, but it did not last throughout the evening. Also, it was too thick for my neck and caused me headaches. The phone pieces that are inside made me concerned that after time they would flatten and the pillow would get firm. I am a hot sleeper and I expected it to stay cool longer than two hours. Because of that I returned it, but if you like thick pillows, and you’re not a hot sleeper, it may work for you.

Decent pillow
Size: Standard Size(1 Pack)
Nice pillow. When first opening it you fluff it and put it in the dryer for about 10 minutes, comes out exactly how I like my pillows, firm but has a little bit of softness. Used this pillow for several nights now. Holds it's shape at the start of the night, but when I wake up its sorta flat and had a smashed feel to it. Fluffs back to it's original size and shape. Just wish it was more dense with about 1/4 to 1/2 more foam inside. Would probably help firm it up and hold it's shape better.

Firm and dense to the Extreme!!
Size: Queen Size(2 Pack)
I love my pillows, extremely firm and also extremely dense. I hate when a pillow gets worn down in the middle after like a few weeks or a month and then you’re struggling to get it full again. It’s absolutely impossible.
When I got these pillows, it said that it might take 24 hours for them to fully enlarge. I enrolled them and took a look at this flat thin thing and I thought, oh my God, I made a huge mistake in ordering these. Went into the kitchen, made some dinner after dinner went into my bedroom and holy moly, these pillows were massive. I was so excited and I couldn’t wait to sleep on them.
Now mind you, I am a side sleeper, so that’s why I like a very full and firm pillow. I do love how full they are, however, it was a little much. Luckily, you can unzip them and take some of the filling out.
A little tip is to keep the little zipped bag they give you and you can put some extra filling in there and zip it and if you ever want to fill it back up, it’s easy. I took about 15% of the filling out of each pillow which to me was perfect, but I could see people wanting to take much more out. I love that you have the option of taking it out and putting it back in if you ever need to, but I don’t think you’ll need to because these pillows will never get squishy or flat. I love these pillows so much that I don’t know if I could ever exist without them. Please never discontinue these because if I ever need to get another set, I want them available.
Best pillows I’ve ever had in my entire life. Period!

QUTOOL Memory Foam Cooling Pillows
Size: Queen Size(2 Pack)
These pillows are incredible. They are thin and shrink wrapped when they arrive, but once open they warp into a perfectly sizes pillow which can be fluffed to your individual needs. They retain their shape and the memory foam conforms to your head while sleeping. They are cool on one side and warm on the other. I highly recommend them and they have a 100 day money back guarantee. This is the pillow I have been waiting for my entire life.
