Are you curious about the different devices available out there for your DIY wired home security system? While most of the highest quality name brand products and wiring can only be gained from utilizing a professional security company to do your installation, there are actually a number of great options out there for DIY enthusiasts like yourself. From motion sensors to cameras to alarms, you can completely outfit your home in such a way that you will be safe as can be.
Smoke Detectors and More
Environmental alarms like smoke detectors, CO sensors, and flood alarms are great ways to strengthen your home security. While many home security products may be focused on deterring burglars or alerting you to a break-in, it’s important that you don’t forget the dangers of fires, CO poisoning, or water damage. These things can be just as threatening to your home as an invader, so don’t overlook the necessity of installing these types of alarms in your home. Smoke detectors and CO monitors should be installed on every level of the house and near every sleeping area, while flood sensors should be placed in areas near water pipes, such as places with sinks or a laundry room.
Never underestimate the power of this little device! There are a number of motion sensor types out there that can do you a lot of good by giving you warning to the presence of an intruder.
PIR sensors use passive infrared to detect the heat of living creatures. Most of these are calibrated to only sound an alarm when they detect the presence of human heat. These kinds of motion sensors work great when placed outside, as they won’t be disturbed by swaying branches or scurrying wildlife.
Ultrasound motion sensors detect motion using ultrasound. They emit sounds at ultrasound frequencies, which bounce off of the objects within their range and reflect back to the sensor, signaling that all is as it should be. When an object moves, these ultrasound waves reflect differently, and the difference triggers an alarm.
Photo detector motion sensors use two parts. One part emits a small amount of light that is virtually unnoticeable, and the other part, a photo detector, is mounted directly opposite it and is made to detect that beam of light. When the light beam is interrupted, the detector notes the change and sounds the alarm.
Door and Window Alarms
Door and window contacts are a great first defense for your home. Many of these are made up of simple circuits. Closed circuit contacts are mounted to the door and door frame, forming a closed circuit between the two parts. When the contact is armed, if the door opens, the circuit is broken and an alarm is triggered. This kind of alarm works the same for a window that is forced open when the contact is armed.
There are particularly a number of window alarms out there on the market today, most of them aimed at detecting the breaking of a window rather than the forcing of it open. Some of these act much like contacts in the fact that they are small circuits applied to the window that break when the glass is broken. Some of this circuitry can also be crafted into the window screens so as to alert you if the screen is cut open. Other window alarms are acoustic, and they are calibrated to detect the precise frequency of breaking glass, which triggers an alarm.
There are a number of devices out there for you to use in your DIY home security system. Thinking about your personal home security needs will help you determine exactly which ones you should incorporate into your home’s defenses.
