Pros and Cons of transformer-powered video doorbell
December 22, 2016
There are two main types of Wi-Fi-enabled video doorbells – battery-powered and plugged-in. The latter doesn’t mean one needs to arrange power outlet on the porch or drill a hole in the wall for a wire to power the device. The modern video doorbells simply replace their older counterparts by connecting to the original doorbell wiring and get power from the transformer that’s already in place.
Let’s find out what advantages and limitations these transformer-powered video doorbells have.
Longer life time
Unlike their battery-powered peers, electricity-powered doorbells have longer life time. Say, if your doorbell is not exposed to the direct sunlight, stays under the roof of your porch getting the raindrops and wind gusts only occasionally, you most likely won’t need to shop for replacement for the next 5 years or even longer.
As modern video doorbells are slowly becoming more of a personal door guards and all come with a handful of useful security features, it becomes essential that the device’s operation is not interrupted. Electricity-powered doorbells are the only ones that are successful in this making motion detection work seamlessly. One needs to make sure that the doorbell model that he chooses for his door comes with the always-on technology.
Operate in extreme temperatures
The home owners who live in places where temperature drops below 20F, just like others, would like to enjoy the benefits of being able to see and talk to their visitors. They most likely won’t like if the low temperature influences the operation of their “door guard”. To make sure that the device doesn’t freeze, check if it has built-in heater that keeps the device running.
Transformer-powered doorbells do not cause soil and water pollution and do not endanger wildlife like their battery-powered peers.
Possible difficulties with installation
In some cases the video doorbell installation might require basic technical knowledge. For example, when shopping for video doorbell one should make sure that the power voltage of his/her in-house transformer is supported by the desired doorbell.
As some models on the market require a diode to make sure that the doorbell works with the door chime, some people might consider installation of the diode as a difficulty as well.
Yet, these days, the marketing teams of doorbell manufacturing companies knowingly predict all the complications that the end user might come across and provide complete installation kits and step-by-step videos and visual instructions to avoid the problems.
Limited choice of location for installation
By default, the transformer wiring is installed during the house construction stage which doesn’t leave many options for the home owner about where to place the new video doorbell later on. Unless the end user knows how to create a separate circuit to power the doorbell, (s)he might end up having no choice but to mount the device at a not so suitable location or even having no space for installation at all!
The size of the doorbell depends on the size of the components used inside it. The size of the components, in its turn, is determined by the functionality and quality of operation of the device.
Some transformer-powered video doorbells might be bigger because of the capacitor - the electrical component that stores electrical energy. As capacitors come in many sizes and shapes, the final size of the capacitor that goes into the doorbell will be determined by the functionality the manufacturer wants the doorbell to perform.
