Productbeschrijving
De Dahua SD1A404DB-GNY-W camera is een hoogwaardige 4MP 4x Starlight IR WizSense Network PTZ-camera, ontworpen voor veeleisende beveiligingstoepassingen. De 1/2,8" 4-megapixel CMOS-sensor zorgt dankzij de innovatieve Starlight-technologie voor een uitstekende beeldkwaliteit, zelfs bij weinig licht. Deze camera beschikt over 4x optische zoom, waardoor verre objecten gedetailleerd kunnen worden gemonitord zonder kwaliteitsverlies.
De camera behaalt een maximale framesnelheid van 25/30 fps bij 4 MP, wat vloeiende opnames garandeert. Met een IR-bereik tot 20 meter en IP66 en IK08-certificering is deze camera bestand tegen weersomstandigheden en fysieke schade. De extra perimeterbeveiliging en gezichtsherkenning zorgen voor een hoge mate van bescherming, ondersteund door SMD 3.0-technologie.
De ingebouwde microfoon breidt de bewakings- en opnamemogelijkheden uit, waardoor deze camera een ideale oplossing is voor beveiligingssystemen. Met zijn moderne design en hoge functionaliteit is de Dahua SD1A404DB-GNY-W een ideale keuze voor de beveiliging van commerciële en zakelijke panden.

Is this the CURE!
Size: Regular, Color: Cream
I have a skin disease called Ichthyosis Vulgaris. Yes, SCALEY FISH! Thanks MOM! This unfortunate crud leaves my heels an embarrassing mess! They are cracked and dry and literally like concrete. I have had this disease all my life and there is NO cure. It's hideous! Anyway, I have tried so many different experiments to help improve my situation. So much time and money I will never get back. So when I saw these, I had to give them a try too because I am a forever optimist and love being disappointed. Here's how it went.
First I put my dermatologist recommended AmLactin on my crusty heels. Then, I put the socks on. By the way, with no problem at all, and went to bed. I was not too hot, which is usually what happens when I sleep with socks on. I never even realized that I had them on. When I woke up, I took them off and immediately used a "Heel File" over a towel removing all the yuck!. Then, I sand papered them to smooth the skin out. Then, I doused them with Shea and Aloe foot lotion I found at the bottom of my experiment drawer in my bathroom. Oh, they felt like someone else's feet. I am very hopeful at this moment! Is this the cure to my embarrassing situation? I sure hope so. Spring is here and I would really like to wear my cute flip-flops when I go to the Waffle House and set at the bar. Wasn't that a picture on Facebook of someone nasty heels? It made me gag. Then, I had to make sure that picture wasn't me! I am going to do this for a week and come back for another review. Wish me luck ya'll!
UPDATE!
So it’s been about two weeks. I wish that I had taken a before and after picture. I guess I figure that this too will be a waste of money. NO! These little socks are a God send for me. I did buy AmLactin foot repair cream and that I highly recommend. It’s the best so far. They also offer an option with heel socks. They are soft and work very well also but one negative. They leave fuzzies on you feet and tools. Guys this is it for me. My search is over! I went to my mani/pedi queen yesterday and she was shocked when she saw my feet. She is spreading the word!

Buy these!
Size: Regular, Color: Cream
I only write a review when I have a strong opinion and want to help others decide. I've been having trouble with cracked heels for months. Previously I had just been using regular socks, but these slip-ons have been game changers! They don't make my feet hot at night. They are comfortable and in the morning my heels feel soft, and I don't need to use them everyday. They look good and fit well even if I want to wear them under socks or in shoes during the day. They really do help if you have cracked heels along with some kind of lotion. Definitely effective!

Cracked heels are gone after 5 applications
Size: Regular, Color: Cream
These moisturizing socks work great. My heels are happy again. The open toe design makes it so my feet don’t overheat at night. It only took 5 times to get rid of my painful cracked heels. Now I wear them 1-2 times a week to keep my heels healthy.

Really nice but needs a few small improvements
Size: Regular, Color: Cream
Super comfortable and the gel lining feels so nice on my feet. They seem to do their job and help with moisturizing and so far the quality has been great. I deducted a star because they can be difficult to clean and may not fit wider feet. Otherwise a great value for your money
