Good morning. I have a 3 storied home that I live in here in Kolkata, India. I want to know what are the basic components needed for setting up a CCTV equipment here in my city. What is the camera quality type that records both at night and during the day time too? I need to install a total of 4 cameras. What is the cost of the DVR, the hard drive, power supply,cat6 cable and what to expect? For outdoors are 360 dome cameras essentials that come with anti dust and rain waterproof I want to have a basic idea. People in here are much more experienced than me and I am here to learn so enlighten me on this subject. Any help or advice is welcome. Thanks in advance have a nice day.
