Hey guys I am new to this forum and I have joined because I do not know much of anything about cctvs. What I do know is that I work from home a lot and often wear noise cancelling headphones in my office....this leaves me completely out of tune in whats going on around me. I am looking for a cctv that I can mount to watch my front door that can transmit the feed (hopefully without running wires all through my house) to my second monitor that for the most part goes unused. I could keep that monitor in my peripheral vision and if anyone knocks I would be able to see them. I am looking for a camera that can transmit live feed to a monitor without running wires all over my house and I was hoping to be able to spend about $100-$150....If this is possible, I would like to see what brands you guys have had good experience with seeing as you're the experts. If you can recommend cameras that may fit this criteria I would love to hear...if my expectations are way too high and something like this setup is going to cost more than I would like to spend let me know that too. Thanks
