Trail Camera Placement Tips
How trail cameras trigger, where to place them (trails, beds, water, food), no-glow vs. flash, false triggers, cellular cameras, batteries, checking them quietly and the rules on cameras, following Wikipedia and Penn State deer research.
A trail camera, or camera trap, is a camera triggered automatically by motion. Wikipedia notes hunters’ use of them for scouting helped build the commercial market and drive many improvements. This guide covers how they work, where to put them, settings, and checking them without spooking deer, following Wikipedia’s camera trap article and the Penn State deer research team. Rules on trail cameras differ between states and land managers, especially on public land, so check them before you set one.
How they trigger (Wikipedia)
- Motion sensors: most use a passive infrared (PIR) sensor, or an active infrared beam; many trigger on movement and/or a heat signature.
- False triggers: anything the wind moves within the sensor’s range, such as plants, can set it off, so clear branches and tall grass from in front of the camera.
- Burst and video: some cameras take several pictures per trigger; video is an option for recording behaviour.
Where to place them
Wikipedia’s advice for camera-trap studies is to target the places an animal uses: runs, beds, feeding areas and other sign, using knowledge of its habits and seasonal behaviour. For deer, that can mean trails, the edges of food and water, rub and scrape lines, and funnels between bedding and feeding. Our reading animal sign guide helps you find them, and our whitetail deer profile covers habits.
Flash type
- Visible flash: Wikipedia notes a camera flash may scare animals so they avoid or even damage cameras.
- Infrared: usually not detectable by mammals or birds, and “no-glow” cameras use 940 nm infrared, outside visible light, so neither people nor wildlife see it.
Cellular or card
Wikipedia notes wireless (cellular) cameras send images over cellular networks so you can see activity without visiting the camera. Card cameras must be visited to collect images. Fewer visits means less disturbance.
Power
Battery life matters: bigger batteries run longer but are heavier to carry in and set up (Wikipedia). Plan battery checks with your card or camera checks.
Checking cameras without pressure
Penn State’s deer research team reports that in one study, using scent-masking when deploying and checking cameras gave some evidence of more white-tailed deer detections, but only at one of two study sites. Whatever you use, keep visits few and short, approach with the wind in your favour, and avoid the early-morning and late-afternoon hours the Alaska Bowhunter Safety Course calls prime time for spotting game; see our wind and scent control guide.
What the pictures tell you
Pictures show which deer use a spot and when, which helps you choose stand sites and timing. Our field judging guide helps assess what you see.
Mounting the camera
A tree or post that offers a perfect mounting position is rare, as Tactacam puts it on its mount page. Two kinds of mount deal with that, described here from the maker’s own pages.
- Adjustable tree mount. Tactacam’s REVEAL Tree Mount adjusts both up and down and left and right, so the camera can be aimed straight from a leaning trunk or a narrow spot over a scrape. It is made of UV-resistant polymer with oversize wing nuts and is built to be adjusted with one hand; its page lists the REVEAL models it fits (Tactacam).
- A post where there is no tree. Tactacam’s T-Post Camera Mount clamps to a fence T-post, so a gate, fence or post can carry the camera. A ball-head gimbal turns 360 degrees, and a ¼-inch, 20-thread stud fits REVEAL cameras and a wide range of standard trail cameras. To stop a camera shaking on a post in high wind, Tactacam recommends mounting the bracket as low on the post as your line of sight allows, since a post sways less near the ground (Tactacam).
