home security tips

Cameras using CMOS technology usually have poor light sensitivity and produces poor quality images. The larger the chip the better images it may produce but you should expect that it is more expensive. The picture resolution of the security camera image can be measured by the number of TV lines. The larger the number of lines, the better resolution and picture quality you can expect. If you will use the security camera in places with poor light conditions, then you should choose the B/W chip cameras that produce better light sensitivity and greater resolution. Security camera systems are categorized into different types. Types of Professional Grade Security CamerasThis type of security camera has box type body that can use different sizes and types of lenses. This enables monitoring objects in any distance. This is ideal for indoor use, but is also recommended for outdoor as long as it has weatherproof housing. These cameras are widely used for commercial installations due to its flexibility. It generally offers great performance along with important features including the backlight compensation, lens control output and many more.

Which type of sensors are equipped on the smoke detectors?Smoke detectors can have two types of sensors: ionization sensors, photoelectric sensors or both usually called dual sensors. The ionization sensor is used to sense flashing fires by detecting the small particles generated by these fast burning fires and triggering the alarm. The technology behind it involves using a radioactive isotope of americium usually, it’s Americium 241 to ionize the air inside a chamber and, if the sensor detects any changes in the air, it triggers the alarm. The disadvantage of using such type of detectors is that they are more prone to false alarms such as when you’re cooking or when there’s a large amount of steam. The photoelectric sensor is more sensitive to larger particles which are specific to slow burning, smouldering fires which could originate from a forgotten cigarette on the couch, but the sensor is not as sensitive to flaming fires.
