Chuango H4 Plus

Acceptable system but only just – Purchased the wifi model as getting to old to crawl around in the roof. Had a few issues connecting it to the wifi but solved that problem after a couple days. Im having the sensors drop off the connection with the main hun which although is easy enough to repair to the hub is a hassle as it's shouldn't be doing it in the first place. I've had several false alarms which again being a wifi unit I expect it. Would I recommend it, prob not as I'm quite disappointed in the unit which wasn't cheap $850 I think. Alarmaustralia have stopped replying to my emails so I guess I just have to suck it up.

Excellent Alarm System - Houses, Motor Homes and Boats – I owned the previous G5W model for a view years using it to protect my motor home. It was able to send SMS in case of alarm. Cons were, full alarm on low battery of sensor, only code configuration by SMS, and at that earlier model/ firmware also notification sounds on 'network loss‘ which was a pain in remote areas. All solved with the new model H4-LTE - it connects to wireless router but works also without (just no camera to add, no web access then). (I use Boost or Aldi for telstra network). Very small data usage through app connection. - easy configurable through app, can be activated deactivated by app or remote control. - no sound when network lost - easy to connect devices like external siren, door and wireless sensors, remotes - door sensors work well in metal surrounding. - sleep mode on motion sensor and solid inexpensive lasting AA batteries in all sensors The outside siren apparently works as stand alone system with motion sensor and remote, no 'hub' needed.

Great technical support by their main supplier in AUS. www.smarthome.com.au So this is an affordable functioning alarm for motor homes and yachts

Update: after 3 years of service, the outside siren was getting quite, and now stopped giving up a sound, strobe still works. As an electrician I had s look inside, all clean, no spider web, nothing to safe… $149 AUD for a new one aliexpress sells 330Mhz, we need 460Mhz here.
