I intend to move from Auckland in 2.5-3 years, so I don't (or think) I want to be laying ethernet cables to outdoor security cameras, since my ONT etc is in the garage, as it was too difficult get the fibre cable to another location which was acceptable to my wife).
I have a Synology NAS (DS216Play, 6GB) and I have played around with their Surveillance Station Software, using my mobile phone as a camera.
My intention is to use the NAS to communicate with 4 cameras (2 extra Synology Licenses will be required).
I thought if I purchased 4 x Wi-Fi cameras and I got the electrician to wire them into the House Mains (I have 12 outside houselights powered by mains power, however, these are on household switches). Some on the wall or under the eaves. I assume all power will be available from within the downstairs hip roofs).
The next issue will be purchasing good quality consumer grade cameras which provide a good picture (4MP?). If I had a choice it would be Dahua, but their wi-fi offering seems limited (see as an example https://www.dahuasecurity.com/products/productDetail/5591).
I would be pleased to hear your advice or suggestions.
FYI - I have had a look at Arlo gear, but want to explore other options first.
