The problem with most "ghost hunters" is that they use substandard equipment, which they don't really understand. But yes, I've met some other folks who actually know what they're doing when it comes to AV equipment, and who are using high end stuff, that report similar issues.
Hi Paul, in your experience and those that you know about, does the piece of equipment get drained when it is 'on' / being used, or does it get emptied when it is 'off' or on 'Standby'.
I wonder if an experiment could be devised using a battery taken into an 'active'/haunted area with a specially designed 'power' monitoring system.
Maybe using chemicals like they do on a packet of Duracell batteries, where you can roughly check/test the remaining battery life by means of a visual indicator on the packet that changes colour according to the power remaining.
I think it works a bit like a litmus paper and the reason I suggest it as being part of the monitoring system is because it does not require a power source to operate itself.
I am just throwing this out so I might not explain every thing well, please tell me if I become unclear.
My experience with rechargeable batteries used in a low range/amateur handheld digital video cameras is that: the on screen battery indicator is quite unreliable especially after a lot of use over time, sometimes it may indicate more or less 'battery time remaining' than it actually has, although this also happens with 'recording time' i.e how much space on left on the HDD/memory card it is less noticeable. My understanding is that all sorts of factors can change both, for instance zooming uses power from the main battery to power the motors etc
I would expect that in pro kit this would be less of an issue, but the point is that the indicator are calculations rather than exact numbers. What I am suggesting is a kind of 'dipstick' rather than relying on the dashboard petrol gauge.
If it was a tyre (inner tube) with a 'slow' puncture I would put it underwater and see where the air was escaping from by looking for the bubbles of air that came from the leak/s.
I am trying to imagine away to do the same with an electric circuit that leaks into the 'ether'. Maybe buy using the same principal as the on-packet battery tester (but maybe in gas or liquid form) as a substitute for water.
Now I have just thought of this, does the complexity of the equipment effect the phenomana's interest in it? or if it can meddle with it at all? for example is it more likely to want to play with a digital camera than a 'film' camera? maybe it could find old equipment easier/harder to mess with because it relies on the 'work' being generated manually? (as in cranking the arm of the movie camera). As funny as it sounds maybe a modern 'movie camera' (using modern materials and design techniques like plastics and hydraulics ((yes a pump up camera))) employing film and a crank shaft could possibly reveal/capture something a digital one wouldn't.
I think the more moving parts the more that can be interfered with or go wrong. And if the phenomena is electric maybe by using low conductive materials like plastic for the inner workings of the camera could help.
out of time but will add more in a bit
