Low voltage wires

Hello,

I will start by admitting that I am an electrically challenged person! lol

I recently purchased a condo and I am prepping for paint.
I have several land line phone jacks in walls that I would like to remove and patch over. Can I just cut these wires and bury in the wall, or is that a potential fire hazard?

I also have an old alarm system that has similar wiring to a motion detector that I would like to do the same thing with.


One other related question. Can I bury a cable TV wire in the wall? There is no voltage in these, correct?

Any help would be greatly appreciated! Thanks! Frank

Thanks,
