In a recent post, I introduced firmware with new features for Browning HP5 model trail cameras. This new version adds several more features — each selectable by additions to the camera’s setup menu. These features include date and time format … Continue reading →
Many trail cameras support both internal batteries as well as an external power supply. When there is only one power source, it’s clear where the power comes from. But what does the camera do when both internal and external power is available? If you use rechargeable batteries inside the camera, and a set of primary batteries in an external pack, which set will the camera use first?

The Browning Elite HP5 series trail cameras have a rich set of features. But, like all computer firmware, it’s not perfect. Based on some Facebook feedback, and our own experience, I identified several small additions of interest to the camera … Continue reading →
Black bears (Ursus americanus) currently range more widely than grizzlies (Ursus arctos) in the lower 48, but where both species roam they are sometimes confused. In a national park where animals are habituated to human viewers, you’re probably more likely … Continue reading →

Knowing the detection zone pattern can help produce more “true triggers” and fewer “false triggers.” In an earlier post Deep Tech: Trail Camera PIR Sensors I covered some of the details of PIR sensors. Based on feedback from subscribers, though, I realized that I had missed some subtle aspects of the Fresnel lens optics and detection zones for PIR sensors. In this post, I look more closely at trail camera detection zones, and how they work. I also give a straightforward way to find the detection zones in most cameras. I use this method to measure the detection zones for three camera models.
