Cheap surveillance project (photo inside)?

Hi all!

I am trying to diy a cheap surveillance system for my home.

I leave in the front of a 2 family house. We have the back wall in common and 3 wall free with a garden all around

I am planning to install 5 IP camera outside and one inside as I show you in the photos below.

The camera on the terrace on the first floor is for someone who try to enter through the roof of my neigh-board ( not surveilled )

Can you tell me:

1) do you thing a video surveillance system would be a good deterrent for bad guys?

2) do you think my project is doable

3) Do you think I can make it with vga resolution or I'll need HD camera if I'would like to have face recognition?

The cameras I was thinking about are these. I know little china - toy camera but i am short on budget for now

Thank you

I would recommend Hybrid NVR / DVR.

This way you can have IP in critical areas like Driveway, Street.

Font door & side of home can be analog to save money.

Thank you very very much for your reply.

Your is a good point

But I am afraid it is not convenient in my situation , My house is already wired with a rj45 cable which I use as home pc network , So I can't use this wires for analog video signalI think that the costs of new wires installation will be easily more than how much I can save with analog vs Ip camera.
