Anyone do wildlife or remote photoshoots?
« on: April 11, 2009, 11:02:40 PM »
Just that I have a great idea for remote live view via WiFi so that the whole live view screen can be viewed on a remote tv/monitor :)

cheers

Looks quite possible. Biologists use something similar for remote camera work, but without the radio part, just using a motion detector to trigger the remote shutter release.

The only things you've got to consider in yours is that there is probably that 'screen saver', where it'll go blank out of inactivity after a minute or so, and the drain on the batteries. If you did want to take a photo, you'd have to work out a separate receiver system and trigger for the remote shutter release, too. How is this different to using a video-baby monitor? Or a CC TV-like system?

Thanks for the feedback winjeel ...

PROTOTYPE:
It is very possible ... it's in a prototype stage at the moment ... and it works a treat ... I grabbed the video senders off eBay for 10 pounds (the ones pictured in the block diagram) ... I will be enclosing the 'audio/video transmitter' and separate 'wireless trigger release' into an old knackered flashgun, so the whole lot can be mounted onto the hotshoe ...

NO VIDEO OUTPUT?:
For those who do not have a video output solution, on their camera, you could add a small CCD camera into the modified flashgun 'head' ... that could then be tilted & twisted accordingly and then transmitted the same way as with Live View but without TTL framing and obviously the frame shot information ...

MOTION SENSOR:
A motion detector was thought of but with Live View you would get the subject where you want it, within the frame and not halfway off the screen when the motion detector decides to trigger it ... but it could be added as a fun feature ...

BATTERY DRAINAGE:
The camera battery would not be so much of an issue as the LCD (or Live View) is turned off (by default) when the video cable is plugged into the camera ... so it wouldn't be that much different having your camera on all the time while you were actually there waiting for the subject to appear ...

As for the video sender TX unit the power drain from that would'nt be that much either ... especially if you used rechargable batteries ... a remote controlled car battery gives us a perfect 7.2v at 3500mAh ... if you're that serious about it that would be an option ...

SLEEP MODE:
On the A300 (and others?) you can set the 'sleep mode' (blank screen 'screen saver') from 1min to 30min ... when it goes into 'sleep mode' you would see it on the remote screen (it would go black) so all you do is half depress a wireless trigger remote to wake it back up again ... and you're good for another 30mins ...

LIVE VIEW:
As Sony A300/A350 owners know ALL of the LCD display icons (in Live View), as well as the focusing, are also transmitted over the video output cable ... therefore onto the remote screen ... so you get all the info displayed before your eyes ... that's quite handy ...

FINALLY:
It isn't that much different to a video baby alarm or CCTV system ... the only difference is that they don't have a video input connection that can be easily wired into ... they're all hard-wired into the camera and main board ... I only used the video senders as an example so others could experiment ... if they wanted to :) ...

It was just a thought going through my mind ... along with a thousand other ideas ...

cheers,
Gem

The OneShow (check out iplayer in the UK) featured a dvd case remote. Basically, remote shutter in a case, with peanut butter on top. Weight of squirrel on the case works the shutter and voila, unusual angle shot off a squirrel.

That was quite interesting on the Oneshow last night and he's on every night this week with different animals - might have to enter the odd photo in to their competition :)
