I have a love/hate relationship with PIR sensors. I like that you don't have to mess with a receiver unit that get's in the frame and that they never false from snow or bugs. I hate that they tend to false from other stuff and you never really know if they're going to suddenly ruin your set by draining your camera and melting your flash (if you leave it on full power). Sometimes their sensitivity seems to vary over time too.

I switched to active IR last year and figured I'd never go back to PIR. However, I was running a Cognysis Scout on a stream a couple months back and the stereo plug connection to the main cable corroded during a rain storm, and I didn't have a backup, so I swapped in a new TRLcam PIR . Jeff has told me straight up that his PIRs don't do well next to water, so I was hesitant to set this one up. His older versions had false triggered when I set them on lakes in Alaska. To my surprise, I got literally zero false triggers during the next 6 weeks or so. I had a Browning Trail cam on the same spot, and my slr got a bunch of critters that the trail cam missed, like a mink, Coopers Hawk, and Screech Owl. By snooting the sensor with a 4" tube, I got the same precise triggering as an active IR. I'm pumped about all this because the active IR was getting about 200 shots/week from falling leaves, moths, bat fly bys, and other misc. stuff, but the TRLcam PIR filtered that stuff out. This new unit also has a waterproof gland passing the cable, which the last one didn't ... plus an option to shoot 1 or 4 shots. I don't find the motion sensitivity settings useful because for me they slow the response time. I set it on the most sensitive setting. This got me into trouble with the older units but this one has been really good so far. If it keeps up I'll use this on a long-term winter set for cougar, which I thought I'd have to use my clunky trailmaster for....

I have the PIR out on a new set in a brushy riparian area. I'll report back on how it does.
cheers

Hi there! Good to hear you like the new TRLcam PIR! I am pretty happy with the former version. Is the casing similar to the old one?

Now if Jeff could come up with a clever way to use this 8*8 pixel IR we could get a super smart camera trap trigger...! (power might be an issue though). I am in for prototype testing... ;)

Jeff refurbished my GH4 video camera trap with the newest remote PIR and I can report similar findings. Although nothing seems as a rock solid as the old Trailmaster 1550s, they don't work for video on the newer 4K cameras. I have some cool lynx, hare and coyote footage thanks to the new PIR. There has been some false triggers where you might expect it, along mountain creeks and such, but it is proving to be very reliable. I will have to try that "snoot", however.

LHH- Ooh that grid PIR looks super cool. If I was still making my own stuff I'd try to make a wide angle PIR turn on/off one of these more power hungry sensors, like LIDAR or this one... or just to wake up the cam so you could use cheap ef-s lenses or mirrorless bodies without issue.

AV you got coyote footage!? I'm so jealous. I have a TM 1550 and I love how it resists false triggers so well, but sometimes I miss small'ish critters with it, tried it for fisher and noticed I was getting some on trail cam and not on SLR, but it's probably user error.

Hey Johnny, the Kyle said been getting over the last 4 or 5 years see-through very young. All the older cayots, in fact the entire population these parts has been decimated by parvo. Some of the conservation officers believe the Cougars are keeping the coyotes from regaining the numbers. Still, I was very surprised to see a coyote so comfortable only a meter or two away from my camera and video light. By the way, I'm loving the new lighting you're putting out. I can testify to how difficult it is to juggle camera trapping and parenting.

Interesting! I'm solving the parent-camera trap trade-off by doing all my sets within a 10 minute drive from home. I thought this was a great idea until the fall rains finally arrived and now I wanna drive 3h to get on the dry side of the mountains. I've been camera trapping in suburban green space and I'm surprised by how the different carnivores can coexist. I'm getting gray fox, coyote, and tons of stray cats on my trail cams -- guess there are enough rats for them to share?
Thanks for kinds words on lighting, having fun experimenting
