These can send motion or sound alerts, I have that turned off because otherwise I’d be getting 1,000 a day as the sheep move around.
I WISH my cameras did that!!! DH picked them out. I think he snags them when Amazon has a sale or something. LOL on the alerts - my main gain is constant on alert - needed. The barn, corrals, stalls, and pasture are scheduled for the same reason as you. Once in a while a door isn't latched good enough and the sheep will pop out into a corral - that's saved us a few times over the years.
$74.30. 
well, buy 2 singles and save! Gotta watch these guys 
Looked up the Wyse cams....Amazon has some discounts. The one you have 33.99 and right next to it is the 2-pk, marked down
I have a set packed "somewhere" from mini horse foaling days. Even ran the cables from barn to house when building. Not the ease of use as now, with apps and all... But they sure cost a LOT back then! Like 10x current. Cams are great -- no matter $$.
I also had a little left on a gift card so I got them for even less. And I got free overnight shipping. I ordered Wednesday evening and they arrived by 0900 on Thursday.
with sleep not happening, I was trolling. There they were -- those V3 cams! 
4, brand new...of course I bid! Ended up with 2 of the 4. $20 each, picking up Wed. Well, other things were attractive and I now have another new toy -- a drone. 
I can practice using it on the still unplanted 12 acres next door. I just wanted one to be able to "walk" my back pastures from the house -- see the animals & all. Has cameras, so pictures can happen but, I just wanted the flyover and watch technology. Zoom, zoom!! 
When Angel was 4 months old she started "playing" with her BFFs. First I separated her from the lambs only allowing her access while I was present. Then I put her in with the rams. They did not allow any nonsense and it worked to stop the behavior. However, she went through a second "play phase" right after she came home from the boarding kennel after her first season. She was in the field with the ewes since the rams were in the small Pen of Celibacy. Had some injuries on the older lambs' legs which required penning them and twice a day doctoring of infected wounds.
Much harder to work with her at that age to stop the chasing/biting/playing. Finally got her through it and she is perfect now. She even stops Ozel (12 months) from running after sheep when they run.
Those cameras sound great. I will look into getting some for my barn in Texas. Here I am only 30' across the driveway to look down into the barn through a window. The barn in Texas is about 500' farther across a field. Those cameras would be so much better for lambing time.

Can you get a crotchety ewe or goat to put with the ewes? He needs one that will "self punish" him. Some people have tried shock collars but unless you are sitting on top of him 24/7 you will not be able to identify the behavior and shock him. I do not like shock collars since the dog learns to recognize when the collar is on and will restrict his bad behavior to times when he is not wearing it. The chasing and play will lead to nipping and pulling wool so needs to be stopped asap.
