Something doesnt sound right. If anything the video trigger should be slower than the Pic trigger - which would make sense as there is more circuitry requiring full power-up. Other than that, I concur with SNH's comment above.... Video may be slower for both, but the 1080 is still starting first.
Also, without a real test of trigger times in both pic and video mode, it would be very difficult to say if it is trgger time or PIR sensitivity you are seeing from your "experience".
I understand what you guys are saying, but I tested both cameras before and some after update. The 720P is still faster in picture mode. For what ever reason when they are in video mode the 1080P starts recording first. I have tested these cameras till I am blue in the face and they are both on the way back to Bushnell. The 720 has froze up some in set up mode(not all the time) I have to turn it off and back on again several times to unlock it. Other times it works just fine. I would not be sending it back if I wasn't already sending my 1080 in due to horrible night video and pics. I do like my 720 and am requesting a swap out for another, but I still can't figure out why the video starts first on the 1080. That is what I will be using the most, especially on scrapes. It may be something to do with the sensor, but they are both set on high.
I have been using and testing trail cameras for about 7 years now and this is the first time I have tested two cameras in video mode and picture mode.
