Sabre Switch Triggersmart Motion Capture System - The Sabre Switch Triggersmart motion capture system is designed for wildlife and high speed photography and can trigger a camera when sound, light or motion is detected.
Once the work of professionals and scientists, high speed photography has been brought into the realms of enthusiast with gadgets like this Triggersmart from Sabre Switch. For £240 this electronic device fires your shutter automatically when its sensors detect sound, motion or light changes. It means you can photograph super fast subjects or timid wildlife. Peter Bargh takes the Triggersmart on a trip into the high speed world of motion capture photography.
Around the back are sockets for the cables used to connect to the two supplied sensors along with a DC in for the supplied power supply and two trigger out sockets for the camera remote cable. There's also a power switch on the back and a sound or beam splitter switch.
The control unit comes bundles with an infra-red sensor and receiver, two mini tripods to support the sensors, two sensor cables and a 3m camera trigger cable with a 2.5mm jack.
- 1/1000sec to 10sec delay
- Light, infra-red and sound sensor modes
- Powered by 4x AA battery or AC PSU
- IP53 waterproofing
- Flash sensor 1- 1500 lumens
The transmitter / sound sensor has a microphone that can detect any sharp sound such as breaking glass, hand clap or balloon burst, while the light detection will trigger when lightening or flash fires.
When recording motion you can use the transmitter and sensor to create a beam that will trigger the camera when split. The beam is about 6 degree angle but can be narrowed using a small 2 degree baffle. This plugs into the receiver and could easily be lost. A slide over cover would be better.
The mini tripods are very light, as are the sensor units. The cable is the heavier item so tends to pull the sensor out of position quite easily. Careful arrangement is needed to avoid any disturbance.
The touch buttons for the various functions click positively so it's easy to turn the modes on and off, but the contrast of colour labels may be hard to see in low light. A lighter colour text would be better. Of course once you are familiar with which button does what you can ignore the labels.
Strobeam DL250 MKIII flash and first did a test exposure to determine the flash distance / position and then loaded the popper with flour to get a nice backlit cloud of powder. Once this was done I switched the Triggersmart on and pulled the popper. The unit performed admirably. Firing every time without any errors. I didn't deviate from the instruction manual's initial settings for this.

I then moved on to a balloon popping. I filled it with water to make the shot more interesting and to pop the balloon I used a barbecue stick with a needle taped to the end. You could use a pellet gun to shoot the balloon. Again the results were spot on on each occasion.

The main flaw was using a flash that didn't have a high flash duration so there's some motion in the shots that would have been frozen with a higher speed flash.
Next I tried using the unit as a beam splitter to record a dripping tap.
The location was a kitchen sink, using the tap as the water droplet source. The transmitter and receiver were positioned at each side of the tap on their mini tripods. I used CD cases to lift the tripods an inch or so. A red chopping board provided the background colour. (this was a just a quick set up. You could do a much higher quality job with the right materials.)
The wine glass was filled with water and positioned under the tap so the drip landed in the centre.
I then had to fiddle around to get the sensors to pick up the drip. The window had to be blacked out as the daylight meant the sensors were not working effectively. This could prove problematic for insect photography in bright light. As the drip was small I also had to add the baffle. It took a while to pick up the motion as aligning the transmitter / receiver was quite precise. A small laser beam in one unit and a target on the other so you could manually align quite quickly would be a worthwhile addition. This shouldn't increase the price dramatically and would make set up and alignment a much easier task. (At the time of writing an alignment aid module has been announced as an optional extra.)
Once in place and working I adjusted the sensitivity knob so that the green light was pulsing in tandom with the dripping of the tap and took a test shot. And it's here where the Triggersmart excels. There's a delay in milliseconds from when the drop breaks the beam of the transmitter / receiver to when it hits the surface of the water in the glass. The trigger delay can be finely adjusted so the camera shutter fires when the droplet hits the water or just after as it bounces back into the air. This means you can record the ideal shape of the splashing droplet. With film it would be trial and error but with digital you can take a test shot, adjust the delay and take another until you have the perfect shape. Again I was troubled by flash duration and in this test, bad lighting / set up, but those are things out of control of the Triggersmart which did its job perfectly.

A video of the Triggersmart in action:
Below is another splash shot - this time dropping a toy into a glass of water. Again I could adjust the trigger delay knob so that I timed the shot with the toy mid way submerged - a millisecond earlier it was hitting the water and a millisecond after floating back to the top with little bubble action.

Value For MoneyAEO Photo produce the Lightning Strike (light detection unit) that sits on the camera's hot shoe. It's small, convenient and, at $137, much cheaper, but no where near as versatile. Similar to Triggersmart is the Time Machine - a US based company with a wider range of accessories, but each bit adds up to a much more expensive product. The Time Machine with sensors and camera cable (no tripods) is $500, but they also produce the drip kit which will make your drop photography incredibly precise.
Well worth buying if this sort of photography rocks your boat.
