, a rainfall, a snowstorm and direct sun exposure, and require additional power supplies being physically routed to them even though these smart device normally can communicate data with a remote server or a
client device wirelessly via one or more communication networks. Each outdoor smart device must be configured to attach firmly to a surface in the outdoor environment, have an access to a power
supply source, function reliably under various severe weather conditions e. g. , water intrusion from a rainfall or snowstorm that could happen, and last for a long duration in the outdoor environment. As such, there is a need to mechanically mount a smart device to an outdoor surface in a compact and robust manner and with a convenient access to a power supply source, while incorporating into the smart device some resistance mechanisms against potential severe weather conditions. Accordingly, there is a need for systems and/or devices with more efficient, accurate, and effective methods for mounting, powering and operating a smart electronic device in an outdoor environment.

Photoelectric
smoke detectors can detect slow, smoldering smoke the fastest, like the thick smoke when a couch or mattress is one fire. In comparison to smoke detectors using ionization technology, photoelectric smoke detectors set off an alarm earlier on slow burning materials. It can detect smoke faster in a large area or in a room with a high ceiling or rooms subject to temperature extremes. On the
other hand the ionization type smoke detector is more sensitive to flames than to smoke. It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood. It is also cheaper to manufacture. Compared to photoelectric smoke detectors, it consumes less power so a small battery can power it for month and is independent of external wiring. Since ionization type smoke detectors can detect particles smaller than smoke particles, they are prone to false alarms. Ionic smoke detectors use a radioactive isotope americium 241, and rules on proper disposal vary in each region. Some European countries have banned ionic smoke detectors.
