Productbeschrijving
Het grootste voordeel van deze camera is de lens met 45 x optische zoom. Deze lens, gecombineerd met een krachtige illuminator, maakt 24/7 bewaking mogelijk zonder extra verlichting, zelfs over een gebied van enkele honderden meters. Dit maakt de camera ideaal voor bewakingssystemen waarbij identificatie van personen of voertuigen vereist is.
Dankzij de "Starlight"-technologie is de camera zelfs bij zeer weinig licht voldoende voor een helder kleurenbeeld. Het door de fabrikant opgegeven bereik van de illuminator is afhankelijk van de omgevingsomstandigheden (luchttransparantie, omgeving, muurkleur, zogenaamde "scènereflectie". Reflectie van de scène).

Best night's sleep ever
Color: 06 - Aqua Gray, Size: Queen (2 Pillowcases)
ABSOLUTELY the BEST pillows I have ever slept on. My husband hates flat pillows and he absolutely sleeps like a dream on these. I HIGHLY RECOMMEND THESE.

Decent Comfort, but Honestly Overpriced for the Quality
Color: 06 - Aqua Gray, Size: King (2 Pillowcases)
I’ve heard a lot of hype about the Beckham Hotel Collection, so I decided to treat myself to this king-size set of luxury sateen pillowcases. Out of the box, they look very nice—the sateen weave gives them a subtle, sophisticated sheen that definitely upgrades the look of the bed. They feel relatively soft to the touch, and the 100% cotton material is breathable enough that I didn't find myself flipping the pillow over for a "cool side" in the middle of the night.
However, after using them for a bit, I’m struggling to see where the "luxury" price tag comes from. While they are perfectly functional pillowcases, the quality feels fairly mediocre compared to other 500-thread-count sets I’ve owned in the past. The fabric is a bit thinner than I expected, and after just one or two washes, I noticed some slight fraying around the inner seams. They just don't have that heavy, crisp, high-end hotel feel that the marketing leads you to believe you’re getting.
The biggest issue for me is the value proposition. There are plenty of other cotton sateen sets available for a fraction of the cost that offer the same—if not better—durability and softness. These aren't bad pillowcases by any means, but they aren't exceptional either. If I’m paying a premium for a "luxury" brand name, I expect the stitching to be flawless and the fabric to feel substantial, but these feel like standard department store linens.
I’m giving these three stars because they do the job and look decent on the bed, but they didn't wow me. If you can find them on a deep discount, they might be worth it, but at full price, I feel like I paid more for the branding than the actual quality of the cotton. I'll keep using them for now, but I won't be rushing out to buy a second set anytime soon.

Great Sheets. Just Not what I was looking for
Color: 01 - White, Size: King, Color: 01 - White, Size: King
I purchased pillow cases which are silky thick and somewhat stretcy.. They felt very high quality to me so i wanted the corresponding sheets as well. I purchased sheets from the same manufacturer but they were made from different materials (my fault for not checking that). The sheets i ended up with very nice in their own way. They are King Size, 100% cotton, and look silky, just not what I thought they would be. They are not that thick but fine. The sheets i wanted were a combination of Cotton, Polyester, and some spandex.

Great sheets and value!
Color: 03 - Gray, Size: Queen
Super soft, cool temperature, grey color matches sample. We got the standard queen for our Murphy bed mattress and it fits perfectly! The fitted sheet stays in place with the elasticity of the banding and the thickness is perfect, not too light, not to heavy.

Soft but very thin
Color: 01 - White, Size: Full
Soft but very thin. Not sure these will last long. Didn’t realize how thin the were until I washed them. They do not come out of dryer wrinkle free. Not horrible but still wrinkled.
