the vibration sensor is for the alert when burglar cutting your padlock/padlock ear on the grill which good enough to trigger the alarm. If the burglar intend to remove the sensor go ahead but he need to think twice before decide to remove them which will posibble to trigger the alarm too.

Again alarm is for notification and prevention not a full proof system. Even you subscribe ADT, they will only offer you help to call Police for ya with yours ack.

Really sad right , high end condo with guard ppl break in , gated guarded also ppl break in , the normal non gated need to be fortified like a prison .......I tot adt will come n check if alarm triggers ?

I think what pg84 meant is, the burglar may detached the vibration sensor from the grill. Because the vibration sensor can be easily detached without triggering the alarm.

But your point is correct also bro, I do agree witha ll of your points. so for those who intend to pasang vibration sensor over main door grill, shall put the sensor over the place where it is hard to be noticed in such away, when the burglar will be very hard to remove it

yes my fren thats what i meant .

There are few ways for a person can enter thru ur grill/door vs type of sensor that can detect.
1-use crowbar ( those really big one ）to force open ,i personally have one so i know how powerful these things are - vibration sensor ( that if they did not detach the sensor first)
2-carjack ( put in between window bar and force welding point to break- happens to my house back window grill) - no sensor can sense that
3-bolt cutter ( to cut thru those thin decorative style of grill) - no sensor can sense
4-electric grinder - extreme case they pretend to be a renovation contractor. - vibration sensor
5-arc welder - extreme case they pretend to be a renovation contractor. - no sensor can detect.

these are the things in my mind when picking a alarm system and i think i still cant find a good one to deter 1-3 yet.
Of cos getting a dog ,motion sensors with lights are some deterent . But purely on prying open a grill i think its not that tough...

2-carjack, yes this is very common way, thats y you need to emphasis this with your grill maker about this, so that the "safety" gap size on the grill is welded accordingly:D

well izzit the aromour window tinted will help, kindda curious whats the grill for, since the vibrattor cant sense the break in

I dont think if using car jack, vibration sensor will not be triggered, as when the break of steel, it will trigger the alarm one huge vibration

There won't be one huge vibration , cos car jack extend slowly , so the welding point just slowly gives away

you can always place PIRs outside the house instead of sensors on the grill. those ones will trigger before reaching the grill/window/door.

how about magnetic sensor placed on window wth grilled inside? izit bettter then putting vibration sensor on the grill?

I will do my minor renovation to my new house. And i want to get your suggestion on electrical wiring wiring and cctv/data cabling.

What i have read is someone advice not to have electrical wiring and cctv/data cabling in one same conduit. OK

But can i have one conduit for electrical wiring and another conduit for cctv/data cabling in same 'longkang' at my wall? Both conduit will be in my wall plaster.

Hi Bro...Yes, I think 2 separate PVC conduit is fine...

Thank you bro..

Hey bro...sorry I read wrongly...I tot you were referring to separate Conduit for CCTV and Alarm..only

As for CCTV/Alarm, vs Electrical wiring...it is advisable to be on a different path..sorry for the wrong info...by right CCTV or Alarm cabling will be on a different path and electrical wiring...thats the standard..

oopss...

In simple words. Data cable (Alarm/CCTV) can't be in same path with electrical wiring.

Is it correct?

Yea...as far as i know..recommended NOT to.

How about Amway Home Alarm System ?

PM me as well..

My alarm installer quote me RM 1000 for labour cost such as wiring, telephone line, no hacking or plastering, installation etc etc. Mine is double storey house. Alarm also buy from them.

Is the price reasonable?
