Hi skshl! thanks for your post, really liked reading it! So if you decided on getting a security system (CCTV) I really recommend you to also get AJAX system, they can update your old cameras and it gives you full control on your cell phone of all the cameras that you got installed, I really like it, I've been using it for years! The also have this cool motion sensors and the battely lasts for 7 years or more, I mean, when I asked myself is my security worth it? Well I think you know the answer.
