Some alarm systems are tied to video surveillance systems so that current video of the intrusion area can be instantly displayed on a remote monitor, not to mention recorded. Some alarm systems use real-time audio and video monitoring technology to verify the legitimacy of an alarm.
Pipe(noun) any long tube or hollow body of wood, metal, earthenware, or the like: especially, one used as a conductor of water, steam, gas, etc. Pipe(noun) a small bowl with a hollow steam, -- used in smoking tobacco, and, sometimes, other substances.
Boilers and pipes are sturdy things, but that also means the heating in most buildings is quite old, and age allows things into those pipes that donât belong there. For water pipes, that usually means air, and in steam pipes, ironically, the problem is water. Pipes sag over time. When that happens (or if they werenât installed properly) steam can condense back into water which has no way to drain back down to the boiler. Passing steam then picks up these drops of water and hurls them at high speed into the nearest pipe fitting, causing a loud, hammering sound.
