Auto-sensing allows the subject to fire the shutter. The shutter fires when the subject trips the the infrared beam. Canon included this as a feature in one of its previous Wireless Controllers – the LC-2 which was compatible with the EOS 1,1N, 5, 600, 620, 650, RT, DCS 1 and DCS 3 – but has not included it in later versions.
Auto-sensing is very useful in circumstances where you cannot get close to a subject. Wild animals are nervous in human company, yet to get the best shots you need to observe them in their natural environment. Often the action happens faster than your reflex can react – take the chance element out of getting the shot by using the Hama IR remote trigger
Transmitter and receiver
A transmitter is positioned to send a continuous infrared beam to a receiver. The receiver is connected via a cable to the remote control socket of the camera. When the infrared beam is interrupted, the camera shutter fires. The distance between the two units for auto-sensing can be around 5 metres (varies with ambient light conditions).
The main cable from receiver to camera is relatively short at only 20cm. If you want to move the camera further away to capture the shot, there is a five metre extension cable available. This increases the versatility of the set-up and will help you frame your shot to better effect.
Both units can be mounted on a tripod or lightstand with a standard 1/4" thread. Alternatively the receiver can be mounted on the camera's hotshoe via a supplied adapter.
Using the IR remote – wildlife
One obvious use for auto-sensing is wildlife photography. Many animals are creatures of habit and follow similar paths at similar times of the day. The advantage of auto-sensing is that you can set the camera quite close to where you expect the subject to be and then move away so that the subject is not scared by your presence.
When the subject breaks the infrared beam the camera shutter fires. With the trigger doing all the work, once you have set up the shoot you can stand well away so as not to disturb your subject. You can use various camera covers to muffle camera noises, such as the Delkin Snug-Its or Heavy-duty rain cover.
We may not all have wild boar wandering through our back gardens, but there's always something of interest to be found in your garden or courtyard, whether it has two legs or four!
Using the IR remote – action
Secondly it can be used for action shots. At sporting events it's a difficult shot to capture the winner across the finish line. With the IR remote trigger you can set up the system parallel with the finishing line, position the camera and sit back for the beam to be broken and the action to be captured.
Check your connection
EOS cameras have one of two remote socket connections – E3 or N3. Whilst the result is the same, you need to make sure that you choose the correct connector to go with your IR remote trigger.

The Hama IR remote trigger also has the following functionality:
– Continuous shooting (only with program, semi-automatic system or manual settings)
– Bulb exposure mode for long exposures
– Timer function with four second delayed shutter release
The transmitter can also be used separately as a wireless infrared remote release (with similar functionality to the RC-6) to fire the shutter.
The two units each run on two x AAA batteries.This frees you up to use the remote system in any circumstance, without worrying about accessing a mains power source.
When setting up your shoot, you need to consider whether the field of action is broad enough. One EOS magazine subscriber has tried to use the IR remote trigger to capture a bird as it emerged from the nest box, but was unsuccessful.
Whilst the trigger is much quicker to react than your finger on the shutter, it cannot be relied upon to capture split-second action. Also the flight of a bird cannot be reliably predicted. We recommend that you think carefully about the intended application.

Hama IR remote
Supplied with either E3 or N3 cable. Ideal for capturing those shots which are too fast for human reflex. Never miss 'the shot' again!
Protect your camera from the elements and help muffle camera noise which can distract or scare away your subject. Fits most EOS cameras with lenses up to 400mm.
Hama IR remote trigger
Auto-sensing was a feature of the Canon Wireless Controller LC-2, but was then forgotten. No Canon remote currently offers auto-sensing. However, accessory supplier Hama has filled this gap with the IR Remote Trigger.
Camera compatibility: all EOS cameras
