How could I improve the trigger speed on my deer cam?

Hi all,

First, I have to inform you that I am a noob in electronics but am willing to learn whatever is needed. There is a lot of stuff on this site and I must thank all of you guys and girls that take time to put your instructables on here.


I have a couple of deer cam (infrared detection camera) that takes pictures of wild game whenever they pass into the sensor range. The problem is that 2 of my cameras have a slow trigger speed meaning that by the time they take the picture, the ex: deer or bear is long gone or I get only 1/2 of it. They are ok for installing on feeders where the animal will stay for an extended period of time but not fast enough to install on a trail where the deer will be walking through.

Is there a way or do you guys have a suggestion on how I could improve the trigger speed for these cameras. Right now, the trigger speed is around 3-4 seconds, which is wayyy too slow. I would like to improve to at least 1sec or below if possible.

The 2 cameras are Wildviews, one is 5.0mp with flash and the other one is 2.0mp with ir flash

Any imputs are welcomed.

Thanks to all

If I understand correctly the sensor 'beam' does not trigger soon enough to wake the camera and then take the picture. If you cannot move the sensor as you said was difficult -- could you attach perhaps a fresnel lens to the front of the sensor to increase the sense area (should work to widen the field of view of the PIR sensor). Another option is to add a fisheye lens attachment to the front of the camera to give it a 180 degree view. The distorted image then can be restored to properly show a regular looking picture in post-processing.

frollard, "could you attach perhaps a fresnel lens to the front of the sensor to increase the sense area" ------------------------- Good idea, the freshnel lens on the camera is a square one, slightly curved but nothing close to the bubble style ones, that would for sure increase the sense area. Maybe put something on top to prevent it beeing activated by branches on top and to keep the detection to the sides. As for the fisheye lens, do you use a specific software to restore the pictures?
I will look into that, thanks for the idea, it worth a try :) .
Photoshop has the 'distort' tool - -one suboption is a fisheye effect, the opposite (I think pinch) restores the picture.

I think the trigger-speed is just fine, it's reporting to you that is slow. You want the IR detectors to report directly to you in real-time (cameras be-dammed)

True, the sensor does it job and reports as soon there is something walking in front of it, it's the camera itself that takes a long time to "wake up". I like the idea of changing the fresnel lens, it should give a wider sensor range and give time to the unit to take the pics. I have another deercam that takes the pictures in less then 1 second when asleep so there must be a way to improve these 2 to respond faster. As I've stated earlier, when installed to watch a feeder, there is no problems because the deer stays for longer in front of the sensor range but when installed on a trail, they are walking sideways closer to the camera so, most of the time, if for example I set the camera to take a burst of 3 pictures, the first picture will be of its butt loll, and the other 2 wont have the animal on it because it already passed.

Would it be possible, or practical, to partially obstruct the trail to slow the deer down? It might scare them off completely at first, but I imagine that they would get used to it.

Kiteman, Thanks for the reply. It would not be convenient for me to have to predict which way the deer would be comming from and if I am wrong, no pictures taken because of it. The camera is one unit with everything included in the front ( objective, flash, sensor etc) and is ment to be installed on a tree nearby the trail so when the deer trigger the sensor, it takes pics. But in my case, if the deer is walking too fast, the camera does not have time to take the picture. It might be the camera itself that takes too long to activate when it is "asleep" and not a sensor problem. I have seen an instructable with a laser beam that when the beam is cut, the camera takes a picture instantly. That would be perfect but in that case, the camera is already activated. When my camera is "asleep", it takes 3-4 secs to wake up, not good at all. Thanks again for the reply, I will see what others suggest. Lion_Heart

Could you move the sensor, relative to the camera, so that by the time the camera goes off, the animal will have reached the area being photographed?
