Quotethe power supply isn't the problem from what my experiments have shown. Even when using batteries, the same action still causes the camera brown-out.Because you are not supplying enough current! The problem is you dont know what everything is rated, (what needs what)

Batteries on the other had can output a heck of a lot of amperage but the problem still persists.
Quotethe power supply isn't the problem from what my experiments have shown. Even when using batteries, the same action still causes the camera brown-out.Your power supply can ONLY produce 12V @ 7.5A, whereas your componets may need 8 - 8.5A. It worked correctly last time when you had 2 power supplies because you split the current. Your single power supply can not handle everything.
what else should I test?
but an o-scope only shows instant voltage fluctuations. It would be gone, off of the screen before I could get a chance to look at it..
Capturing Minimum and MaximumValuesThe MIN MAX Record mode captures minimum, average, andmaximum input values. When the input goes below the recordedminimum value or above the recorded maximum value, the Meterbeeps and records the new value. The Meter stores the elapsedtime since the recording session was started at the same time.The MIN MAX mode also calculates an average of all readingstaken since the MIN MAX mode was activated.This mode is for capturing intermittent readings, recordingminimum and maximum readings unattended, or recordingreadings while equipment operation precludes watching theMeter. The MIN MAX mode is best for recording power supplysurges, inrush currents, and finding intermittent failures.Response time is the length of time an input must stay at a newvalue to be captured as a possible new minimum or maximumvalue. The Meter has a 100 millisecond MIN MAX response time.For example, a surge lasting 100 milliseconds would be capturedbut one lasting only 50 milliseconds may not be captured at itsactual peak value. See the MIN MAX specification for moreinformation.To activate the MIN MAX mode, press M. As shown inFigure 6, the Meter displays e at the top of themeasurement page, and the MIN MAX start date and time alongthe bottom of the page. In addition, the recorded maximum,average, and minimum values appear in the secondary displaywith their respective elapsed times.Restart119.81VACStopStart : 06/07/07 7:00 pmMaximum 127.09119.50110.23AverageMinimumAuto RangeVAC 500 VACVAC00:03:1701:10:0900:59:59VAC8:10pm 06/07/07Min Maxest42.epsFigure 6. MIN MAX Record DisplayTo stop a MIN MAX recording session, press M or the softkeylabeled Stop. The summary information in the display freezes,and the softkeys change function to allow saving the collecteddata. Pressing M again or the softkey labeled Close exits theMIN MAX record session without saving the collected data.Measuring Duty cycleDuty cycle (or duty factor) is the percentage of time a signal isabove or below a trigger level during one cycle, as shown inFigure 25.The duty-cycle mode is optimized for measuring the on or offtime of logic and switching signals. Systems such as electronicfuel injection systems and switching power supplies arecontrolled by pulses of varying width, which can be checked bymeasuring duty cycle.
Your fluke should have some features to allow you to see how low the voltage drops either ysing the max/min capture (100ms resolution) or duty cycle (which may have the shortest measurement interval).

It does but why would use that instead of the historical graph? Does the min/max have a much faster cycling time or something?
