I have been in the market for a DIY security system. This wasn't what I was looking for but offers some neat features that might appeal to some.
"Kit includes four Smart Plugs, two Motion Sensors, two Window/Door Sensors and one Hub Unit*. Control lights and other appliances remotely and sensor monitor your home. You can receive alerts, arm and disarm system via smartphone/tablet.
*Requirements: 1) A wireless router with the internet connection; 2) iPhone 4 or later, iPad, or iPad mini (iOS 6.0 or later), or an Android device (Android 4.0 or later)"
The actual surveillance cameras can be purchased separately.
Caught my eye because its significantly cheaper than other places:
Myer: http://www.myer.com.au/shop/mystore/panasonic-panasonic-kx-h…
AO: https://www.appliancesonline.com.au/panasonic-kx-hn6032azw-h…
Michaels Camera Store: https://michaels.com.au/products/panasonic-kx-hn6032azw-home…
Can be paired up with Bing Lee ebay deal if you wait till 30/1: https://www.ozbargain.com.au/node/289725
Shipping was cheaper by $1 when I tested my postcode on their website vs. ebay. May not be the case for everyone.
If purchasing from ebay - don't forget cashrewards.
That's a good price, seem to sell for more than double.
