More home renovate-y type questions:
I want to put a burglar alarm / home security system into my house. I previously had a DIY-kit-jobby from Max Security (like these, but I think it must be an older model: http://www.maxsecurity.co.nz/catalog/max-index-c-DIY_Home_Security_Alarms-cPath-27_170.html). However, the tenants we had in our house have pretty much rooted it (broken aerials, broken sensor things, etc).
The alarm worked pretty well for what seemed to be a fairly basic DIY install (loud sirens, reasonably sensitive detectors etc.)
We're now moving back into the house, and I need to either replace the broken bits and see if I can get it going again, or replace it with something new (whether similar model from same place or a complete alternative).
However, before I get too carried away down the wireless-DIY path, does anyone know what sort of frequency the wireless communications work on (the communications between the sensors and the central unit/siren)? When we last lived in the place, we didn't have a wifi network, but by the time we move in it is very likely we will. Do the wireless sensor units interfere with wifi (or vice versa)? I would assume the unit had to have come with a sticker about frequencies, but the tenants put pay to that theory.
I'd also welcome any suggestions about good alternatives. Basically I am looking for:
- Not monitored (I have no particular desire to be stuck with these charges)
- Must have both IR sensors (the ones that go in the top corner) and reed switches or similar (monitoring when doors get open), less concerned about the glass break thing.
- Big plus if it worked on cell phone network (i.e. send a text/SMS if the alarm is triggered). The old one I had dialled any pre-programmed number over POTS, but I'm currently considering doing away with the phone line all-together and not really sure whether these units are VOIP compatible (alternatively, VOIP compatibility would be a plus).
- Does not matter whether wired or wireless (walls are coming down, so will have the opportunity to run wires). Obviously if wireless will interfere with wifi, then wired is going to be a very much preferred option
- Not too concerned whether self install or professional install (so long as cost not prohibitive)
- Not too concerned whether remote control or pin number key pad control
- And obviously reliable, actually work etc.
- Price is not a defining issue, but I do want reasonable value for money - i.e. I will pay more if I actually end up getting more or a noticeably better product.
Any advice most appreciated.
