The ST-1W2A-3 Fiber Transmission System (Transmitter) from Meridian Technologies incorporates an all-digital encoding technology that transmits one real-time, simplex 10-bit video channel and two, 24-bit audio channels in one direction over one optical fiber. This model uses singlemode fiber. It is well suited for use in intelligent transportation systems, security & surveillance work, access control, among many other applications and settings.

NTSC, PAL and SECAM video formats are seamlessly supported. It uses 3-pin terminal blocks for audio channel interfaces. The SC series is also compatible with Meridian's SpectraSmart Network management and diagnostic PC-based system.

The DigiSlim product family is available as rack mount cards and modules that can be installed in any of Meridian's desk chassis or in 19" racking frames.

Amazing Bilingual Books for Kiddos!
Format: Board book
We are obsessed with the Si Sabo Kids books! We got the first set of Street Vendors and now this is such a great addition. Our daughter loves these and reads them over and over. My husband is a spanish speaker but I am not, so this has been a great way to pass down spanish to our daughter regardless of whether you speak spanish or not. Plus, the case the books come in are so cute and stylish sitting on our bookshelf. Really makes a great present because it's a great set!

Love this set of books!
Format: Board book
As a dual language educator and mother of a bilingual child, I absolutely love these books! The set is bright, colorful and culturally rich; the three books are inspired by Latin American marketplace scenes, which makes learning feel playful and meaningful! Such a wonderful addition to any household or classroom bookshelf!

Q-tips-an all around great thing to have
Size: 500 Count (Pack of 2)
Q-tip brand Q-tips are very soft, thick, easy to use and a good value for the money. I use them with my business as a skin care professional. They’re extremely versatile.The smaller size is perfect for skin care of the eye, or ears for example. At home, I use them to clean my jewelry, to apply makeup, plus several other uses. They are gentle, strong and safe.
