We have 4 cameras in our old barn for calving. Bought many years ago - cheap, wireless, but barn is in 100 ft range. (receiver & 1 camera was about $150 and each additional cameras were $100 each - which we purchased as gifts over a few years).
We built a new arch steel building & using both barns for calving. Been looking for a camera system for new barn, which is 280' from house. Finally found what I wanted from Sportsmansguide. Receiver & 2 cameras, $120. Security Man brand.
I called the Security Man direct & talked to a sales rep. Explained my situation, and he said it would go 330' clear view - no obstructions, but would only go 100' thru buildings. Said I couldn't purchase one & send it back if not happy with results.
So, I figured Sportsmanguide would take back anything, so I ordered it & tried it. I "assumed" it wouldn't work THROUGH the steel building, so we set up both cameras in the door opening, leaving the sliding door open about 8", and put the receiver in our bedroom, upstairs. Works like a charm!!! :banana: :banana:
I'm a happy camper!
Just thought I would share this info because we had a thread about this some time ago and others were looking for a system to use. Security Man tried to sell me a different system that was getting up towards $1000. Not for me!
True - most systems are expensive - but for $120, it is MORE than worth it to me - to lay in bed & click a button to see what's going on out in the barn.
Also, not just the lazyness (and not wanting to leave my nice warm bed for whatever might be waiting for me outside) I find that by not going into the barn to check things, I don't desturb any cow/heifer that is in labor.
Besides - it was Christmas present!
If they had them in infrared that would be a slick deal. Don;t have lights in the calving area unless I turn them on and then it's only right at the building
Well, I'm going to call. Supposed to be -20 deg wind chill this weekend and I have calves coming. Lazy or not, here I come!

These ARE infra-red. Can see the cows without lights. Technologie keeps getting better & cheaper.
What's the number of the cameras?
Have no clue ??? so I cut & pasted info from their website:
but I didn't buy it from them -they were more $$$$ - price was $160 from them.

Are those numbers good bad or indifferent???
I was very impressed with the quality of pic. Better than my old ones that are 1/3 the distance - but they ARE in the old barn with block walls.

Don;t know all the tech crap, but if I can get 200 feet even if the IR distance is only 23 feet I can still cover a lot of our calving pasture.
The only reason I posted this info was because I thought it was such a good deal. I've been keeping my eyes open for something that would work for our new barn since we started that project.
I know I referred to being lazy using it - but, I truly feel it is a good management decision (also :D ) - they get checked much more often - and don't disturb any progress that has been started. Also, you get to make sure calf gets right up & sucks without having a new mom worry about people.
