Simple technology, move on it and let's progress it. No patent on this sort of stuff so competitors and Eyepark themselves need to bring it. The cons will go away as the product is polished, enhanced and improved.
The mention of ONVIF...ooo I have a rant that has been building for a long time for that structure. Soon is all I can say.
Mobile is our next future. I can see beyond that but when I mention those technologies all the sheep just baaaaah. Drop all your plastic, burn your money. Stop using a physical mailbox. Mobile is the new standard, step up all of you dreaming at night seeing parts of the puzzle, gather up and post that which you feel, draw what you have seen, discuss that esoteric tangent that plagues you. Do a back flip.
Our progression is cultivated in our thoughts. -UD #1,2,3,4,5,6 and beyond.
