Hello from the wild east of the EU After a burglary attempt and some trespassing incidents I decided to install a simple surveillance system around my house. I'm planing to buy 4-5 cameras, probably cheap bullet cams with wide-lenses like IPC-HFW1320S for well lit front of the house and street, a turret for installation on terrace roof in moderately lit area (probably IPC-HDW4431C-A) and a starlight bullet cam (IPC-HFW4231E-SE?) for backyard where it gets really dark. When it comes to NVR I'm leaning against using a NAS due to motion detection problems or PC due to unacceptably high power consumption of i5 system running 24/7. Probably I'll buy something from Dahua and WD Purple 3-4 TB HDD. Questions: 1. Most important: is the camera selection correct or there is a better solution for similar price? Unfortunately I can't afford to buy 5 most recommended starlights now and there aren't many opinions on cheaper cams here. What I need is reasonable night vision to see what's going around and motion detection with e-mail or push notifications, I don't count much on recognizing somebodies face because while working for few years for judiciary I've seen only once or twice a recording of unmasked burglar. 2. Is there any performance difference between NVR4108HS-xx (black box) and NVR4108-xx (smaller white box) and are there sufficient for my system? 3. Would you recommend one of the above NVRs in PoE version or a separate PoE switch (thinking about Netgear GS108PE)? Will I be able to easily separate cams from the internet using non-PoE version and ASUS-WRT based router? If i get non-PoE version because I can place NVR under my TV and don't have extra 5 ugly cables in my living room. 4. Will I get better results using two cheaper cams installed 10 meters apart or one starlight to monitor dark backyard? 5. Is there any PC NVR software, preferably linux one, which can run on machines with power consumption significantly lower than i5 system? Bluecherry maybe? I've read somewhere somebody running it on some old junk with less power than modern 10W Apollo Lake CPU.
