The biggest problem I have capturing images of wildlife is not getting close enough to the subject. I never have enough time to sit and wait for them to come to me or they are easily spooked, and fly away at the first sign of movement. Using an simple, widely-available PIR motion sensor, I can leave my DSLR in the yard to capture images while I run errands, cut the grass, or even leave it out overnight.

Step 1: What Is a Camera Trap?

The Simple PIR Sensor DSLR Camera Trap uses an industry standard PIR sensor to send a signal to a DSLR camera to fire the trigger when it detects motion. I have access to Canon cameras so this Instructable is specific to Canon DSLRs with an N3 connector or stereo connector, but this will work with all DSLR cameras that have a shutter input port. A PIR sensor is what is commonly used in home security motion detectors. Instead of tripping an alarm, we are going to use the PIR sensor to fire a camera.

This Eastern Bluebird was fairly predictable on where he would land, only if the yard was free of people. By placing the Simple PIR Sensor DSLR Camera Trap aimed at his perch, I could set up the sensor, set focus, exposure, shutter speed, and ISO on the camera, and walk away. This image was captured at distance of 10' allowing for greater detail and a pleasing background blur.

<p>Or you could call it &quot;automated National Geographic reporter&quot; :D</p><p>Brilliant idea and stunning implementation!</p><p>good luck with the contest!</p>
<p>great idea and brilliant photos i am going to try this </p><p>you have my vote!</p>
<p>Beautiful. One point though, why would someone need an SLR (Single Lense Reflex) when there is no one to watch through the viewfinder?</p>
<p>Better quality images.</p>
A camera being DSLR does not mean better quality it only means that the camera is digital plus it shows same image through viewfinder that it captures through lens.<br><br>Better Quality is by the pixel and contrast rating of that camera.
<p>I forgot to add my thanks for posting this tutorial. I only wish all of my old lenses for film would work on digital camera housings. I've just finished setting up a trail camera, so I can catch the antics of a pine squirrel, as it uses the feeder I made. I had to modify the feeder by adding swinging doors to block birds from eating all of the food.</p>
<p>If you don't main wait for a mont, you can but a PIR sensor from china for less than a $1 US dollar! http://s.click.aliexpress.com/e/yNRZrr3</p>
<p>Where does one buy a &quot;PIR Sensor&quot;?</p>
Thanks! I've never heard of a PIR before. This is fascinating.
<p>Oops... Your material list shows a 3 AA battery pack, equaling 4.5 VDC, but the photo indicates the pack is 8 AA's, equaling 12 VDC.</p>
<p>Fixed. Thanks for noticing.</p>
<p>I love the shot of the raccoon - wonderful work, thank you for sharing.</p>
<p>Brilliant! Do you know if this could be done for a Nikon camera?</p>
<p>I only work with Canon cameras, but as long as you have a method to trigger your Nikon with a cable, you should be able to use this Instructable.</p>
<p>Super project. I will have to try this. One camera only has a wireless remote. Any easy way to make this circuit operate that remote? </p><p>Thanks</p>
<p>If you want more information about camera traps and wireless remotes there are several different forums. Camtrapper.com will have the most information related to DSLR camera related stuff. Another useful site for camera traps is hagshouse.com and diytrailcams.com You maybe able to find someone on camtrapper.com that has hacked one of the wireless remotes to use for something like this. </p>
<p>Thanks for the tips. I will check out the info. Excellent project.</p>
I've never used a wireless remote for my camera trap photography. I'm not sure how to mod your remote, but I'm sure its possible.
<p>Great project !</p><p>Can you give me more detail on the PIR sensor please?</p>
Great captures; great photos; must be a great proximity trigger. No wonder they say English is the hardest language to learn. The inconsistency is ridiculous.
<p>Nice; with my camera I would have to turn off the power saving, and add a power pack for my camera, but I like this.</p><p>Has this Instructable not been accepted in a contest yet.</p>
Wow nice pictures! <br>It looks so simple this way, good instructable and keep up the good work :)
<p>Nice project! Great pictures!!</p>
A great project if nothing other than for the Red squirrel Picture,... Brilliant,. and so lucky to be able to see a Red Squirrel,.. we only have pesky Grey ones where I live....
<p>Very nice and simple, I like it. I built a similar device a while back, more complicated, I built it for a friend, still did not receive any images from his camera :) (he mentioned that the device is working fine, he has images with his dog, but no wild animal triggered it yet :) ). -&gt; https://www.instructables.com/id/PIR-Sensor-for-DSLR-Photo-Camera/</p>
well done citizen!
