Look at webcams such as those manufactured by Axis.
Also, to be honest, you don't just want something to record and store for ten days because :
(a) that will require a lot of storage space
(b) that will require a lot of post-processing time looking for interesting footage
You want something more intelligent that will record 5/10 minute clips on a trigger event (movement / sound / sensor etc.).
Oh, and if there's the possibility you might want to show the footage to the Police, take the time to ensure your recordings are made and stored in a legally admissible form otherwise they won't be interested in it.
