The First Alert 2 in 1 steered clear of the ionization sensor and only went for the photoelectric type. The photoelectric sensor is better suited at detecting larger particles usually from smouldering fires, that don’t erupt immediately into flames by using a light beam inside the detector which doesn’t directly hit the sensor, but will do so in case smoke enters the device and forces the light towards the sensor. Besides the smoke detecting sensor, the First Alert 2 in 1 also has a Carbon Monoxide Electrochemical sensor which has the role of detecting any rising levels of CO inside the room and triggering the alarm when the concentration crosses the safety levels there will be both visual and audible signals – up to 85dB at around 10 feet. If the sensor detects increasing levels of Carbon Monoxide, the CO LED will flash a red colour and the audible alarms will have the following pattern: four beeps, then pause, four beeps and then pause. Otherwise, if the sensor detects smoke in the room, the Power/Smoke LED will flash a red colour, while the audible alarm will beep three times, pause and again three beeps and pause. You can silence any of the alarms by pressing the Test/Silence button: if the smoke alarm has been silenced, then it will remain silent for about 15 minutes before reactivating if the smoke has not been cleared; if the CO alarm has been silenced, it will remain silent for up to 4 minutes before reactivating again if the CO levels haven’t decreased.

Having a security camera or a set of them installed strategically around your property can be a great convenience in a number of ways. If you have nice cars or items on your property such as tools you can use constant video surveillance that can be digitally recorded in case of the event of a loss or theft. As long as you have homeowners, renters, or auto insurance on the items that were stolen or damaged you can get reimbursed for the property. The home security company will then call you to confirm that there has been a break in. If your home security alarm is triggered then you can be sure that local police officers will be there to assist you in a matter of minutes. Many home security system companies provide their customers with signs and sticker to show that they are protected by them. The mere fact that you have an alarm system installed on your property will deter most criminals from attempting to break into your home lowering your risk of possible intrusion. Home security systems offer many other types of protection for you, your family, and personal belongings. Many systems come with sensors that can detect smoke, fire, and even carbon monoxide. With the home security system industry being as competitive as it is, you are sure to find protection at a reasonable price. Do some research and compare not only the price but the levels of protection the company is offering.
