Types of Indoor Alarm
Motion sensors
These sensors are generally placed at entryways and in large rooms. As the name suggests, motion sensors send an alert (or alarm) whenever they detect motion, and they often work hand-in-hand with security cameras (they activate the cameras to record the motion). This way, you’ll be able to see the perpetrator (or the plant that fell from the counter) and even keep a recording of it for evidence or what have you.
Door and window sensors
These are similar to motion sensors, but they only detect if the window or door they are attached to is opened. These can be great for doors and windows that are on the other side of your house, or the rooms you visit less frequently.
Freeze sensors
These sensors will alert you about very low temperatures that could potentially freeze pipes. This allows you to wrap the pipes or take other preventative measures to keep pipes from freezing and breaking.
Heat sensors
Different from smoke alarms, these sensors are set off by rapidly rising temperatures indicative of fire. They do not need to detect smoke to be activated, so if there isn’t much smoke present (or the smoke is blowing the other direction) these sensors will still work to help keep you and your home safe and secure from a potentially catastrophic house fire.
Flood sensor
Most useful in flood-prone areas with basements, flood sensors alert you when water levels are detected so that you can take the necessary action to prevent further damage to your home.
Glass break sensors
These sensors are set off by the high frequency sound of glass breaking, alerting you of vandals or burglars. Needless to say, if someone breaks your window to gain access to your home and valuables, you’ll be the first to know.

Enhanced Security: Deter potential intruders and quickly detect unauthorized entry.
Peace Of Mind: Know that your property is protected whether you’re home or away.
Remote Monitoring: Access your system and receive alerts from anywhere via mobile apps.
Insurance Discounts: Many insurance providers offer reduced premiums for homes with security systems.
Integration: Modern systems can integrate with smart home devices for added convenience.
Fast Response: Professional monitoring ensures rapid response to emergencies.
Property Value: A security system can increase the value and appeal of your property.
