In the beginning … was the Word 🙂
Way back in eons past when I was first involved with CCTV all the systems were hard wired, which meant you had to run wires all over the place from your cameras to a Analogue VCR somewhere at a central location. I remember one time I had to run wires through a loft in California in the middle of a usual hot day, the temperature was over 121 degrees in that loft, ugh, nasty day.
The cameras needed wires that had a twofold purpose, one line was to carry the video signal and the other line carried 12 volt DC to power the camera, seems almost funny now because most so called wireless cameras now run on 5 Volt DC either from a power supply are even on-board rechargeable batteries.
The Early CCTV systems were the Analogous magnetic tape type, meaning that the storage media then was a VCR which was a magnetic mechanical spinning head which transferred the video images to a magnetic tape, so once one tape was full you had the choice of either removing the VCR tape and replacing it with a new one or over-writing the old videos on the original tape.
Move over VCR it’s digital time.
In the late 90’s things were headed quickly into the digital realm where everything was either on or off, kind of how Digital might be explained that way, it is either a one or a zero there is no in between unlike the analog system where there is a variable quantity, kind of like a dimmer switch (I am of course speaking in simplistic terms to try and get the point across)
So after the VCR we had the DVR or the Digital Video Recorder, these were a better option mainly because of the size of the storage media, you see a DVR can use a hard disk drive a bit like you have in your computer and that can hold far more data than you could fit on an old VCR tape.
The DVR could be placed in a central location in the home and have cameras connected to it either by wires or wirelessly but the second option would involve a wireless network to be up and running in the home. Once you have a wireless network running then you have the possibility to do away with cables all together and start using a NVR or Network Video Recorder.
I said in the previous paragraph that you could do away with wires all together, well, at first the cameras still had to be plugged into a power source, so they may be called wireless cameras but in fact the first ones were not, because they still needed a power source, and it was not until later that true wireless cameras came along that had their own onboard power source or battery. Now it is possible to plonk a wireless camera in the middle of your garden and if you have a solar panel to connect to it you can forget about having to change or charge the batteries making it a truly wireless device.
Going wireless requires a wireless network.
In simple terms a wireless network depends on a wireless router ( like the one pictured below) to keep signals whooshing around your home keeping all your wireless devices happily chattering away to one another. In basic terms, you have the internet out there somewhere and everywhere, and that is usually brought into your home via a cable, that cable is then connected through your computer to your wireless router, your wireless router then throws out signals to your devices like your cell phone, laptop, printer, security cameras etc etc, and vice versa keeping everything connected without wires.
This is all done safely and securely proving you have set up your password for your router properly.

Here is a couple of IP Cameras that i recommend to you for their simple/easy set-up
Pan/tilt (L/R & up down)
Two way audio
