Security System Wirless or hard wire

[colbra]

Hi I am just about to get a Bosh security system in my shed I spoke to the people selling the system and it was there opinion that a hard wired system, would be easier to calibrate.
I suppose the meaning of that is, if a mouse came in the shed the alarm would not go off but if a person came in they would trigger it.
The senses are infrared and microwave or may be lazier not to sure any advice would be appreciated
Also do you think a cattle fence run around the in side of the shed about 50mm out from the wall would be a good idea that way if the person removed a sheet of iron and tried to step into the shed they would fowl them selves on the live wire and give the alarm a chance to go off before they could take any thing......I HOPE:rolleyes:

I don't have an alarm system as such, I have CCTV with sound and I can set it to be motion activated with alarm. Even though I haven't needed it YET (maybe the sign is a deterrent?), it was explained to me that this way I could prove who the perpetrator was.
The problem I found with wireless was that I needed power for the sensors so, as I didn't have a power point close to each sensor, the wireless part was somewhat lost.
Be careful with the cattle fence, you could be sued for harming the intruders :roll:

Col,

That has made my day, using a cattle fence.....lol, next time when I am outside your workshop refusing to go in, you will know why:U.

I think an alarm is a wise decision, but unfortunately after many years in retail, I have come to realise that if they want to take it, eventually they will find a way, so my suggestion, if you have not already done so:

* Take photos of everything, catalogue what you have, and engrave what you can, photocopy receipt and keep one at home and one at another place with a disk with photos and asset register (in case you have a fire)
* Talk to your insurance company about what you have, and make sure you are covered
* If you can afford it, add video surveillance, it does not have to be an expensive system, I have one, and it is not to catch the criminals, it is to prove to the insurance company what I had and that it was stollen. Catching the criminals would just be a bonus.

As far as wired/wireless, I am definitely no expert, but I have always preferred wired systems for reliability.

Good luck with the cattle fence idea, and make sure your wife knows about it:oo:.

Cheers,

Camo

If possible, use wired, you still need a back up power system , so if the power is cut, it would still record for 30 minutes or so. Amos:)

First make it obvious with signage that you have a system. Better to prevent intrusion than record them being there.

Wireless can have quality problems and with a tin shed this could become a problem. Make sure your recorder is housed in a secure location that is not obvious or they will take it with them - defeats the trouble of fitting it in the first place.

My recorder has a noisy fan and hard drive so it was easy to track down in a quiet house. Think about a UPS as a back up supply.


Like the cattle fence idea. :)

Edited: Sorry just read the post and it is an alarm system you are considering so my post is useless as I am talking about security cameras. :-

A couple of points FWIW.

An alarm system is simply a mechanism to get the message out. Sadly it will not chase the litte b.gg.r down the street. Keep in mind you need a 24/7 response force regardless of wired or wireless even when you are asleep or down the local. Same as CCTV set up in video motion except that video recorded evidence might be useful later on.

Not sure where the calibration thing came from but it will not be associated with the wired or wireless question or the devices. The wireless systems were largely developed for the home installer market. No wires makes for a simple installation but the wireless signal will be degraded if you expect it to go through a tin shed. Read the instructions (wireless or hard wired).

Regardless of how it gets there, all active devices require power. In the case of wireless, everything requires power to transmit alarm status, even a reed switch. In the case of wireless it will be battery power. In the case of hard wired the answer is obvious.

Just remember, if you elect to go with wireless, the remote devices should transmit low battery status back to the panel (and the remote force [you]) before they die otherwise the whole thing becomes a lost cause.

Another point to consider. Put a decent dead lock on the door(s). Then the little b..gg..s will be forced to take what they want out the way they came in rather than via a door they can unlock from inside.

Finally, keep it simple. Do not attempt to overkill with more than one reed switch on each door and one volumetric detector total. Failure to keep to this simple rule is serious sleep deprivation.

Hi Colbra, I use to design, manufacture and install security systems up until about 10 years ago.


With your intended set up, the biggest problem you will strike is that caused by the tin shed walls.


In high wind events they tend to move but the temperatures they generate in summer can actually cause them to blind infra red detectors.


While a lot more work, but it may be far more advantageous to fit passive sensors like reed switches on doors and bars on window and if possible some pressure mats in areas where it is likely to be high pedestrian traffic movement.


There is also the advantage that by using passive devices, you lower the power requirements of the alarm system which mean it’s back up battery will last longer if the power is cut, deliberately or by blackout.

Hi All! First off I must apologise for not getting back to my post and acknowledging all reply’s. At this stage we are nine days into the thread Security Systems Wireless or hard wire this is now the state of play.
As of yesterday I had a hard wired system installed.

Security System.
A Networx NX4 security panel with back up battery, tamper circuit and built in dialler for future monitoring if required. Panel to be fitted in the workshop as discussed.
A code pad at the entry area.
A Duel Tech detector fitted to the centre of the rear wall.
An internal piezo screamer.
An external strobe and siren in a poly tech cover fitted to the rear gable.
Australian made with a 3 year warranty.
Security window stickers & a corf lute sign for the rear fence.
A power outlet for the alarm panel.

I have been sitting at the back window all night waiting and watching to see who was going to break into my shed, so I could see if the alarm worked and how much noise it made and how bright the strobe was. And maybe just a little bit to annoy my next door neighbour who threatened to report me to council for making too much noise in the shed and interfering with the TV reception. Alas nothing…… so now I thinking have I wasted my money if no one ever breaks into the shed although it is early days.....LOL :U
Just to sum up on things and on a more serious note the company is family owed great service…… well so far anyway and is called Centron. CENTRON - Communications and Security - Home security, Home security Central Coast, Wireless security, Wireless alarms, Burglar alarm, Burglar alarm central coast, Home burglar alarm, Home burglar alarm central coast, Back to base alarms.

Thanks for the update, very interesting, maybe you can "accidentally" try the door at 2 AM, !!:D, all in all a very informative thread, thanks to those that contributed. Amos:)
