Using Wireless Internet CCTV to Detect Fire and Flood
December 23rd, 2020
Wireless internet CCTV cameras are more than just CCTV cameras. Unlike their old analogue predecessors, these cameras allow you to see your property in Omaha, NE from anywhere, over the internet. More than this, they can be used to alert you not only to movement within the camera view, but also to emergencies like fire and flood as this article explains.
Most internet CCTV cameras have the ability to raise the alarm when motion is detected within the camera’s field of vision, giving you the chance to log in over the internet and see what’s going on. However, many of the good quality cameras can raise the alarm when other events happen in the vicinity. They do this by “listening” for signals that are sent from sensors when conditions change, for example in those extreme cases when there is a fire or flood, and by sending text messages or email alerts when such signals are received.
The type of sensor you use will depend on the type of event you want to protect against. You could buy a heat sensor and set it to trigger when the temperature exceeds a certain level. This could be used to detect a room becoming too hot, a freezer breaking down or a refrigerator getting too warm inside, for example. You would use a moisture sensor to protect against flood. This could be placed in a basement or near a washing machine. Normal industry-standard sensors will work with all good makes of camera, but you should check the trigger voltage and wattage of each to make sure. In all cases the sensor will send a change in voltage to the camera so that it can take action, as the next section explains.
To attach sensors to your camera, it needs to have a so-called digital input port. Most of the reputable makes of internet CCTV camera have one. Two wires are attached to connectors that make up the physical exterior of the port, and these wires run to the sensor. The camera is programmed to recognize a change in voltage at its input port caused by a signal from the sensor, and to act upon it immediately. Typically it will send you an email and also an instant SMS text message to your mobile phone or as many mobile phones as you choose. You can then log in over the internet to see what is going on, and if necessary call the emergency services, all within seconds of your sensor detecting a problem. Of course, it takes some technical work to get your camera working in this way, and you will need external service providers to handle things like sending SMS text messages. If you don’t like the thought of setting this up yourself, I always advise getting a pre-configured camera and monitoring service from an internet CCTV provider in Omaha, NE.
Using wireless internet CCTV cameras in this way really broadens their role. Seeing your home in Omaha, NE from wherever you are is just the start. Attaching sensors and programming the cameras to act upon their alerts turns your camera into an all-round automated property monitoring system that keeps you informed about any problem in your property, within seconds of that problem arising.
