In the last couple of weeks we brought and installed a sensor light come wifi security camera from Bunnings. It a hard wired job and I think the Brand was Orion and was $150. I was a bit sceptical at first, but it's surprisingly good. The video quality is a bit better than 1080P, but not quite 4K from memory. Whatever resolution it is it's pretty good quality video footage, with a zoom feature, that records on a loop to a micro SD.
What I liked particularly was that it uses the 'grid connect' phone app for camera monitoring, that doesn't have any ongoing fees, but I get real time alerts on my phone if the sensor is triggered day or night, can watch live footage from the camera etc whenever I want. The camera set up is via the app also and it's pretty simple in all honesty, even though there's a multitude of set up options and features. There's a number of different types of cameras and security devices that utilise the grid connect app, and I don't think there's any limit to the number of devices you can run through the app. Mine also has a built in two way microphone so you can talk with say a delivery driver if they rocked up to deliver a package.... or better still allows you to ask someone why they are peering into your windows.... From your phone you can set off an inbuilt alarm which is both loud and annoying, which hopefully would be a further deterent.
I plan to buy a second one and mount it under carport to watch over our cars.
