When most people think of monitoring their home security system they think primarily about its ability to alert the police of a break-in. What they aren't aware of is the lesser know capabilities of the modern alarm system, which is environmental monitoring
For example: you can monitor the amount of carbon monoxide that is present in your home. Smoke Detectors, water level sensors and low temperature devices
can also be monitored by home security systems. Although monitoring of these devices is becoming more popular it will be some time before it becomes a regular feature of every system.
News accounts have helped push the awareness of these capabilities. Every time there focus is placed on the effects of radon gas or other dangers such as fires in the home there is an increase demand for this type of monitoring.

Unfortunately it takes a tragedy to motivate most people to take action. Adding environmental monitoring devices to a new security system or existing ones is relatively simple. Once installed, the alarm system is programmed to make an audible sound or silent alarm depending on what type of device is being monitored.

If you have a low temperature sensor to prevent freezing pipes you wouldn't want the siren blasting you out of bed in the middle of the night but you would want to know if there is too much carbon monoxide in your home.
For those who are aware of the full capabilities of an alarm system it may come down to the cost issue whether or not to add extra equipment. Although cost is a valid concern one should also consider all the risks involved.
A break-in takes a human and a conscience decision to target a particular house. Where as fires and other acts of nature are not so discriminating. Think about all of the things that run on electric in a home. Any one of them has the potential for starting a fire.
Don’t get me wrong; I’m not talking about spontaneous combustion but normal wear and tear to the electrical cords etc. A fire or a flooding basement can damage an entire house costing many thousands of dollars. A break-in on the other hand is less likely to reach the same level of damage
When put into this perspective it’s not as hard to justify the cost of the equipment versus the potential risk you can avoid. Check with your insurance agent to see what discounts they give for monitoring your home security system.
