Wireless 802.11b and Wireless Alarm system.

Goosey

Hi Guys and Gals,
I've recently moved into a new house. I am currently using Eircom homestarter BB with their Netopia wireless modem/router. May not be the best kit in the world but it works and does what I ask of it. ( plus the company pays for it )

The missus wants to get an alarm in and shes been talking to the sales folk that came knocking.

She has it in her head that we are going to get a wireless alarm system or I can use my fist :eek:

My query is ....does anyone know if the signal used by the Eircom wireless phone watch interfer with 802.11b or G signal to the router?

Thx,

Goosey

It shouldn't. Check that the Wirless Alarm doesn't operate in the 2.4GHz range, and it should be fine.

The phonewatch website doesn't give technical spec of their equipment. Don't believe the salespeople when they tell you it won't interfere with your router (and they will say that). They have no brain and a penchant for barefaced lying.

Cheers Seamus ....that's what I thought when I asked them the quesion and got a blank vacant stare for about 2 secs.

If at all possible AVOID a wireless alarm system. I had the misfortune of 'upgrading' an existing (but older) wired system to a wireless one, hand have been plaugued by a 300% rise if false alarms from the PIR, and the panel reporting loss of conntact with certain receivers.

There isn't an issue with WiFi, as the levels of errors were the same both before and after it was installed. We went back to a wired system but with a new panel and detecttors and all is well.

Wireless is only successful were a wired system would be impractical - for a house alarm or doorbell, it's worth the effort to follow the wired route!

Yea, 2.4Ghz is bad for wireless networks as I found out. I have wireless video senders that I plugged in and my network died. Hence I'm selling the video senders

eircom phonewatch operates around 400 ->430 mhz if i remember, strangely enough those wireless oil tank meters can feck up phonewatch, but phonewatch wont make a difference to your wireless network.

Had the same problem with loss of contact and false alarms, after 5 visits by the engineer he adjusted the antennae in the control box to go diagonally across the box instead of down the side (which btw was against a solid wall) ... since then absolutely no problems at all in 3 months.

Phonewatch wireless works on 4+ GHz - I've had this and a wireless network in the house for 6 months (Phonewatch panel and wireless AP in the same hallway - no more than 30 feet apart) with no problems at all ...

I've had no problems at all with my wireless alarm system (Phone-watch) and my 11b wireless router. I also have wireless audio/video running, and some RF sockets and a microwave.

They all work perfectly well together.. We just need to wear tin-foil hats in the house at all times.

BTW: Phonewatch may not be too keen to install a wireless alarm system if they know you have broadband.. (it certainly is the case the other way around, i.e. installing BB if you have a wireless alarm system). They'll probably try and charge you an extra 150 quid for a 'special' engineer! In my case, I lied, and told my BB provider I didn't have a phone-watch alarm (and everything works fine), but it may not be as easy in your case, where the phone-watch engineer will be performing line tests etc., so it's probably in your interest to tell them up from you have their DSL product.

If your phonewatch is a 'cream' coloured box with a mans voice, it works on 319.5mhz

If its a white box with NO voice, its operating on 433.0mhz ('Piece of white trash' us engineers used to call that one... )

If its a white box WITH voice and two big ugly aerials up the top, it also works on 433.0mhz - or VERY recently 868.25mhz.

They don't use Ghz at all - they're not permitted.

Ah god bless DA Systems :rolleyes:

But The Security Man is correct with the frequencies and they are well away from the sort of frequencies wireless networking uses.

It looks like we might know each other Redshift??

Did they screw YOU in the end as well, like they did ME ??
