What is visual compare? Our system takes a snapshot of the area selected and compare it with the snapshot of the same area previously taken.
And web-compare? Here you can select an element of the page to be tracked. Our system monitors and compares the snapshot within the selected element.
Which one is more reliable? Both systems have the same 100% reliability in detecting changes.
Which one generates less false alarms? The element system generates less false positives as is immune to page layout changes.
What are the limitations of element? You can’t have a % trigger (“only alert me when 10% of the page changes”) and doesn’t work will non-HTML or PDF's.
Which system I chose? It really depends which system creates less false alarms. We recommend starting with web-compare and testing visual compare after.
