Productbeschrijving
Met zijn ingebouwde 2 MP CMOS-beeldsensor maakt de PIR-camera snapshots met hoge definitie wanneer hij indringers detecteert en stuurt deze door naar de alarmhub, waar ze vervolgens naar de mobiele app of alarmcentrale (CMS/ARC) worden gestuurd, zodat u visuele alarmverificatie kunt uitvoeren. De camera maakt gebruik van 2.4G RF-HD-transmissietechnologie om de resolutie van beelden en de snelheid waarmee ze worden verzonden te verbeteren. De camera is gebouwd om u veilig te houden en beschermt actief uw privacy door alleen snapshots te maken wanneer er een indringer plaatsvindt.

Clean, comfortable staple for casual business wear
Color: Black, Size: Medium
Every wardrobe needs a sharp black button-down, and this JEMLDL Oxford shirt hits the nail on the head for versatile styling. The fabric has a nice, substantial weight to it—it's classic oxford cotton that feels durable but remains soft against the skin.
The fit is tailored nicely without being a restrictive slim-fit, and the integrated back pleat gives your shoulders plenty of room to move without the shirt pulling untucked. It features a traditional chest pocket and a crisp button-down collar that holds its shape under a blazer or worn casually open over a white tee. It washes up great and doesn't shrink up into a mini-shirt after a cycle in the dryer.
Pros:
Heavy-duty, high-quality oxford cotton weave.
Back pleat offers excellent shoulder mobility for active movement.
Versatile styling that dresses up or down effortlessly.
Cons:
Like all quality cotton oxfords, it requires a quick iron or steam to look crisp.
Fits true to size, but has zero elastane stretch in the fabric.

Nice Quality, Great Fit, and Very Comfortable!
Color: White, Size: XX-Large, Color: White, Size: XX-Large
I ordered this shirt for my husband, and he is very pleased with it. He says it is a really nice shirt that fits true to size and looks sharp. The fabric has a great, quality weight to it that gives it a structured appearance, making it versatile enough to easily transition from a casual day out to a more business casual setting at work.
The biggest selling point for him is how comfortable it is. He mentioned that it feels great against the skin and offers excellent mobility throughout the day, thanks in large part to the classic back pleat design. The chest pocket is a nice, practical addition, and the classic Oxford style looks great right out of the dryer. It is a well made, reliable closet staple that he is already getting a lot of use out of, and we highly recommend it!

An excellent button down that fits well, looks great, and feels as good as it looks.
Color: Navy Blue, Size: X-Large
From the office to dinner and the to church on Sunday, this is a perfect shirt for any situation.
It even looks great worn open over a t-shirt with a pair of jeans and boots or tennis shoes. Who said a nice button down needs slacks and dress shoes?
It is a cotton?polyester blend so it is lighter weight than a standard cotton oxford. It also isn't as crisp or harsh and it doesn't wrinkle nearly as bad either.
The sleeves are a standard long sleeve but they cuff well. The shirt looks great when cuffed too so that helps when it's hot and humid.
There isn't really any stretch to this shirt but that isn't a problem becuase it is perfectly true to size. Just follow the size chart and fit is near guaranteed.
For only 20 bucks, basically, (22 to be exact), this is a great choice for any situation when a nicer than completely casual look is desired.

Husband approved
Color: Khaki, Size: X-Large
I got this one for my husband too, and it is a really nice shirt. It has that classic Oxford look that works for a lot of situations, whether he is wearing it for work, dinner, church, or just trying to look a little more put together.
The fabric feels comfortable but still has enough structure that it does not look sloppy. It is not stiff or scratchy, and the fit looks good on him without being too tight. I also like that it holds its shape well and does not seem like it will need a ton of fussing to look decent after washing.
The style is simple in the best way. It pairs easily with jeans, chinos, or dress pants, so it is one of those shirts that can go a bunch of different directions depending on what he wears it with.
Another solid husband shirt. Comfortable, clean-looking, easy to style, and definitely something he will actually wear.
