Yes, there are many different lockable racks that you can bolt to the floor and or wall. That along with a good alarm system should do the job nicely.

Tell them you are having problems with a poltergeist, who is moving objects around. You had ( a ghost-busters team) install nanny cams throughout the house in order to capture movements. You don't know locations of the nanny cams, so ask them to keep this in mind when having sex or whatever. lol

At work we use a piece of software by the name of rapid eye. Depending on the rights that the users are given you can do this. Besides just being able to see security cameras, you can also setup different zones to give off alarms and so forth. I am not sure how big of a business you are talking about or how much you want to invest, but it works for us and we have over 100 cameras running on it at a time. You can also write the video off to a hard drive for future playback.

The sound is measured in decibels. There should be a tag inside the smoke detector with that information.

I am a paranormal investigator and have caught many things on tape.a cheap emf detector as long as it is used with caution can be found at wal-mart. in their hardware department. I use one called live wire. it is an ac sniffer just turn down the sensitivity way down and stay away from ac lines . and when you come across an emf field the tester will flash and beep.. cost about $10 have video of this in use investigator was standing still aking questions and telling spirit to make the tester beep faster or slower acording to the questions answer.. kind of cool.. \n\nhttp://www.kiestronics.com/nwopis

not a lot of people know this but smoke detectors are one of the biggest scams ever! I had one in my old house, one day it started beeping and beeping like their was a fire every so often. And then it stopped. Three months later a grease fire destroyed my kitchen and that good for nothing smoke alarm didn't even go off.

Go on line and check out surveilance equipment or bugs.  You will find many stores that sell equipment that you can purchase to check your house and phone.  Placing a bug is relatively easy, finding it can be difficult.  They have devices that only require that they be in a location to have a clear path to your home and then point the device in that direction.  It will listen and hear everything going on and no "bug" has to be placed.

How about...."home alone"\nYou could review all the devices that can monitor the safe running of the home whilst not occuppied.i.e. burglar alarms.\nThere is now a device to call you when water is detected from broken pipes.Maybe you could come up with some new ideas not yet available.\nHope this helps.

It helps to spy on the neighbours when they have their windows closed

The factory alarms are documented in the manufacturers literature.  The home-made alarms are all different from each other and reflect the intellect, personality and experience of the installer.  Some alarms are silent in order to provide a better opportunity to catch the thief.\n\nThe best way to learn about alarms?  Install a variety of different alarms on different cars.\n\nIf someone tries to steal any of my cars, I will look forward to handling the issue permanently in a manner that will result in no charges pressed by the DA against me.

I bought a wonderful webcam with motion detector and infrared from Webcams4u which can be found on Ebay, or on the internet. Their prices are great and I think I paid £10.00 for mine, it also has a built in microphone
