The funny thing about model numbers is they sort of make sense, but not always. Fortunately, VoIP Supply is here to help with our dedication to help make the buying process easier! Today we discuss the naming convention of a particular favorite brand of mine, Vivotek:


  • IP (ex: IP8331) — Network. Think of it as IP, like Internet Protocol, even though all of Vivotek’s cameras are network cameras (and most are PoE, though not all), this naming convention tends to be the default for most box, cube, and bullet cameras.


I learned the word ‘tanstaafl’ during my macro-economics class in college.  While it’s used as a word, it’s actually an acronym.  If you don’t recognize it, prepare yourself: There Ain’t No Such Thing As A Free Lunch.

Box chain stores carry surveillance cameras that are a couple bucks.  Here at VoIP Supply you’ll see them run into the several thousands.  Truth is there is a whole lot of quality difference.  Don’t worry, this article shouldn’t be preachy…too preachy.

Simple:  If you want to keep an eye on the house while you’re away or just need to monitor the front door of the office, a good IP camera would be right for you, such as Grandstream’s indoor GXV3615WP_HD or their new outdoor model GXV3672_HD.  …

Vivotek has released a new series of extreme weatherproof speed dome IP cameras.  Aimed at replacing earlier models, the new Vivotek SD83xxE PTZ cameras will of course have IP66 rated enclosures for tough outdoor conditions from snow to desert extremes.

The new Vivotek Outdoor PTZ IP camera series will also provide:

  • Joystick controlled PTZ features with 360° continuous pan and 90° tilt functionality with automatic patrol option.
  • H.264 compression including MPEG4 and MJPEG encoding for flexible video streaming tailored to your needs.
  • Wide Dynamic Range (WDR) Pro support for challenging lighting conditions.
  • IR-cut filter for true day/night functionality.
  • Local data storage on an SD/SDHC card slot.

Model Differences

The main differentiating factors in the new models are resolution and optical zoom capabilities:

  • SD8311E:  18x optical zoom at 720×480 D1
