I recently built one with my raspberry pi and the camera module. It was stupidly easy, all the difficult parts (motion detection, saving short video recordings) are all done for you.

I upload everything to s3, and set notifications on the bucket to my phone. If motion is detected, I get an email within a few seconds.

If you're serious about not being spied on, the only reasonable thing to do is to build it yourself. Luckily, these days, that's very easy and cheap.

How can you be sure you cannot be spied on, if you upload to the cloud?

If I was that paranoid, I'd encrypt the files. However I trust Amazon not to look at the contents of S3 buckets (being caught doing so would severely damage their business).

The threat of bad publicity for his employer discourages Andy from looking in the S3 buckets. But it also stops Bob blowing the whistle if he sees Andy looking in the S3 buckets.

If you're paranoid, you can always encrypt before uploading.

Any chance you could point at the libraries you are using?

There is a Linux program called Motion that I use to monitor my IP cameras.

It records to a location of your choosing and has pre and post motion detection hooks allowing you to email the pictures or videos to yourself when motion is detected.

IME it works quite well. I setup one camera and motion uses about 60% CPU, but there was no noticeable increase when I added camera 2 3 and 4.

There's a program called `motion` that I've used in the past for a similar setup.
