I'm looking for a camera for my barn. I have been told repeatedly to avoid the 2.4ghz because it interferes with the internet connection and that I should get a 5.8ghz camera. So how do these people that have 2.4ghz keep them functioning even with all the household interference??? Whats the best way to go? 2.4ghz is cheaper by far with more options
Take the covers off and vacuum really good. I have a problem with the one nearest the air return and it's because it gets dusty. The dust will cause it to go off. So, every time I change the air filter, I vacuum out the smoke alarm. Havent had any false alarms since I started doing that.
change the battery or just replace it..
Vacuum it to remove buildup of dust. But better to replace it.
If the smoke detectors have been in service for 8 years or more, or if there has been a heavy smoker in the house, the sensor can become covered with a thin film that makes them oversensitive. I suggest you simply replace the sensor.
Composition Early mirrors were often little more than a sheet of polished metal, often silver or copper, for example the Aranmula kannadi. Most modern mirrors consist of a thin layer of aluminium deposited on a sheet of glass. This layer is called the Tain. They are back silvered, where the reflecting surface is viewed through the glass sheet; this makes the mirror durable, but lowers the image quality of the mirror due to extraneous reflections from the front surface of the glass (ordinary glass typically reflects around 4% of the light). This type of mirror reflects about 80% of the incident light. The back side of the mirror is often painted or coated in some way to completely seal the metal from corrosion. Mirrors for precision optical applications are more likely to have the reflective coating on the front surface of the mirror, to eliminate reflection from the glass. Metal films on the front surface are generally covered with a thin, transparent coating to protect them from corrosion. This is often made of silica. In some cases this coating may also enhance reflectivity. Mirrors designed for special applications, such as in lasers and other advanced optical devices, use a reflective optical coating composed of many layers of different dielectric materials. Such coatings can be designed to have extremely high reflectivity and are reasonably durable. Since they absorb very little of the incident light they can be used with high power lasers without absorbing the energy and being damaged.
