Haven't got the maplin one but one similar that i use to watch the farrowing house, means i'm not in and out disturbing mum to be or the other pigs. Its saved many a piglets life as i've been able to dash outside at the right moment. i'm also a fretter

so it gives me peace of mind. OH bought it for me as he was sick of me disturbing him & the dog

but i know he secretly watches it too
We had a sow last year who just would not settle to farrow and after a long while of watching her trying to nest and flinging herself about i went out, managed to get her laid out and when she next had a contraction, helped her out with the most gi-normous piglet, she had a further 5 with my help, if it hadn't been for the camera she might have likely exhausted herself trying all night to give birth and likely the piglets would have died within. The 6 piglets saved more than covered the cost of the investment in the camera. Same pig has just had a litter of 10 this month again with my cctv supervision.
