I bought my basic set up (NVR + 4 cameras) from this local supplier and he's been very helpful with some problems I've had (plus there's the 3 year warranty.) So I don't mind paying a bit extra for that coverage. He's still trying to get prices for me but even said he understands if I purchase the camera elsewhere.
I've also chatted to Andy a bit and he's very helpful - even though I haven't purchased anything from him yet. I rather stick with Hikvision for the compatibility with my NVR- I've got my one Dahua cam working, but it's not as "user friendly" as the Hikvision cameras.
I'd be concerned people would think I had some sort of drug lab with a camera that big!?
There was a story on the local news about a guy who has been caught and the first footage they showed of his house was some big PTZ cams set up around the house. Then there was a 60yo widower who had a person break into her house- she had a couple of cameras and it's made me wonder if people assume you've got some sort of illegal activity going on if you have a camera set up. I put mine up after a neighbour mentioned some shady character was casing out their cars and looking in the windows in the early hours.
So far I've only discovered that we've got a resident fox that visits regularly (in suburban Adelaide.)
