When the festive season rolls around kids have a fear of being put on Santa's 'naughty list' and not getting their Christmas presents on the big day.
While most are on their best behaviour, some little ones like to push the boundaries, and if the Elf on the Shelf is running out of magic there's a new alternative.
A £2 'Santa Cam' bauble is available from high street store Wilko, which is designed to look like a mini video camera and even has a red flashing light on top, reports the Mirror.
The Christmas tree decoration looks like it's recording and sending the footage straight to Father Christmas at the North Pole.
The product description at wilko.com reads: "Kids are sure to behave with our Santa Cam Bauble.
"The tree decoration is fashioned into a 'camcorder' and features a flashing red light (with on/off switch) to simulate that it is recording.
"The tree decoration comes with a ribbon tie for hanging."
It adds that the product requires three LR44 size batteries, but these are included with it.
Wilko adds: "It's part of our The Night Before Christmas range; a festive story that focuses around the activities at the North Pole on Christmas Eve.
"This is a decoration not a toy. Keep out of reach of children under 3 years. Small parts. Choking hazard. Always read label."
The bauble has been a big hit with shoppers so far, garnering a number of five-star reviews.
One customer wrote: "Brilliant idea the grandkids loved them, Santa keeping his beady eye on them with the flashing light works great."
Another said: "I bought these because they looked lovely and thought they might do the job of keeping and eye on the little ones who think they can take bits off the tree and make them be good so Santa can bring them presents.
"I did not realise they had a red flashing light on that makes them even more realistic. Great fun."
You can purchase the Santa Cam bauble online or in-store.
