Isn't wear leveling specific to solid stated drives?  There are surveillance specific hard drives, but as far as I know the differences between a surveillance drive and desktop drive is that the surveillance drive is built to withstand the 24/7 constant use of a surveillance system, as compared to a desktop drive which gets intermittent use - read a file, idle, write the modified file.

I find the "WD purples" overpriced, surveillance hard drives (both magnetic and solid state) are available from other manufacturers with similar capacities at more attractive pricing - I'm running Seagate SkyHawks.

Thank you all for the great answers!
I have an old PC that I don't use, so I think I will go with the idea of an IP camera and setting up a server myself.
Other option is to expand the project to cover the whole yard and go with the good old DVR.
Bicurico:
Old PC as a video surveillance Server seems a bad idea to me.
Will you be using a safe and updated OS?
What is the power consumption of the old PC vs dedicated surveillance hardware?
tom66:
Agreed.  My DVR pulls about 5 watts including HDD.  Every camera an additional 2 watts when IR is on, 0.5 watts when IR is off.  So you would be racking up a big power bill.  At 30c/kWh a PC using 60W continuously will cost you $157 per year in electricity alone, so even if you had to buy a $100 DVR you'd be cost neutral by year's end.

How old is old?

The added functionality you're getting is so much better. For example: running BI with DeepStack (https://www.deepstack.cc | AI object recognising) beats a lot of false notifications. Using the built in motion detection of most camera's is not great (to say the least). I had them trigger on basically every thing, cloud (shadows), trees, etc.  |O The Deepstack makes it so much better, I nearly removed all false positives.

An I5 under full load runs ~ 50 watts. Just make sure you use SSD's.

Since the sensitivy of the data, I would always make sure you shield that PC or NVR in proper fashion. Nothing is safe.

Just my 2 cents.
