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.

EDIT: proofreading.

Most wireless systems use 433Mhz.

I would never touch a wireless system unless it was temporary. A wired system is far superior. If you have no knowledge of alarm systems however I would not recommend installing a wired system yourself. It's easy if you know how but there are plenty of things to get caught out by if you don't know what you are doing.

Thanks for this - probably a stupid question but my knowledge of schoolboy physics is now failing me - will this interfere with wifi (2.4 GHz?)? I know there is no overlap in the frequency, but is there any kind of destructive interference? e.g. like the microwave or cell phone messing with all sorts of things? Not sure if that makes sense or not.

Yeah, I figured as much re wired vs wireless. And about doing stuff wrong.

Is it possible to get a wired alarm installed profrossionally that doesn't come with some sort of monitoring contract though?

433Mhz stuff won't interfere with WiFi

As for an alarm without a contract there are plenty of people who would do this but you're going to end up paying a more for it as with many alarm monitoring companies you'll get a subsidised alarm for entering into a term contract. A good basic system like a Micron unit with 4 sensors and internal/external sirens and cable will cost around $350ish incl GST but you would then have to get somebody to install it. The problem is that very few electricians or installers would sell you an alarm at cost price so I'd expect you would probably pay somewhere around the $800ish mark to get a alarm system and installation without a contract.

AlarmNZ do some really good preconfigured Micron panels that are available from Corys/Mastertrade, if you ring one of their stores they're bound to give you some details of electricians or installers who they are selling them to and you might be able to ring around and get a good price.

just got this thread re oppened as we have recently been burgled-another thread on that.
I too have been looking at alarm systems and this thread seemed related.
Been looking at Jaycars for some of there gear.
Points to note is that we are renting-hard wiring systems not an option.
Something we can take away if we move.
Just wondering if the item in their catalogue LA-5145 in there catalogue would suit.
Anyone using this piece of electronic wizadry ?>?

In all seriousness if you did want a wireless system Aliexpress would be the place to look, you're going to pay waaaaay less than somebody selling them locally!

Not sure about your budget, but if you want a really good system then you should look at the Visonic Powermaster systems. They have a range (free sight) up to 2000 meters, the transmitters in the detectors will adjust their power, so that the closest detectors to the central unit uses less power (and battery) than the detectors that are farther from the man unit.

Sends text messages when there is an alarm, and can be controlled via text messages (on and off). Has camera PIR (motion detection + camera) and a huge selection of detectors.

Have sold these kinds of systems for DIY market in Norway for 11 years and very seldom have had any returns because of technical problems. Have had lots of problems with other systems.

More at Visonic.com: http://www.visonic.com/Products/PowerG-Wireless-Property-Protection/pg-control-panels/powermaster10

There is a New Zealand importer of Visonic gear, but I have not found the system on their website - http://www.redlite.co.nz/

Check out this thread for some thoughts. Someone linked to a place that does wireless DIY installed alarms up in Auckland.

I for one have nothing against wireless security alarms. Very little wiring.


My one is over 11 years old and was fitted by previous owners of my house.

I have only had to replace the SLA battery once.

Have to replace the PIR batteries every couple of years when reported on the main alarm control box.

Think it might be an FAI brand.


It achieves all my requirements and better than not having an alarm:

Fob remote access.

Extremely loud internal siren

Very loud external siren and flashing beacon (beacon good to let watchers know the alarm is being set/unset)

PIR detectors (3)

Plenty of warning stickers on doors and windows.


I am anticipating getting a Jaycar wireless alarm when I buy my next house.

Cheers

Gordon

If anyone wants un-biased professional (8+ years experience) with regards to wired vs. wireless alarms, please feel free to PM me.
I'm a Security Tech, and I won't try to sell you anything, I'll just give you accurate advice.

Go wired if you can, otherwise Paradox and DSC do great wireless systems

The stuff you can get at a retailer (jaycar, etc) are pure crap, you definitely get when you pay for.....

Well I guess a opportune burglar does not know if you have a cheap or expensive security system.

A determined burglar will not worry what protection you have.

Mind over matter.

In the end went with an Exodus System

http://www.exodussecurityalarms.co.nz/index.php?route=product/category&path=64_94

I think its a reasonable price and reasonably sophisticated.

just wondering which of the exodus products you endet up getting and how it worked out for you? im in exactly the same position right now, were renting, been broken into, are now looking for a security system but there are so manny ranging from cheap to expensive. Something mid range would be good.

I'm all for wireless (we have a Lockwood so running cables is a no go).

I got mine off Ebay. Came with 3 PIR's, 5 or so door/window sensors, 4 FOB's and a siren. The main feature of the panel I was looking for was GSM and the ability to turn on/off remotely (our previous hard wired alarm used to false trigger all the time).

I think I got the alarm for around $250 but there are loads on Ebay (although AliExpress is getting better I still prefer Ebay). Just make sure it has GSM support or an "App". Search for GSM Alarm and there are loads.

With the GSM I use the on/off acknowledgements to activate my cameras via IFFFT.
