Reolink Doorbell Battery Review
Moreover, it works with Alexa and Google voice helpers, which is useful for smart home setups.
The doorbell carries a 7000 mAh built-in Battery. In lab tests it lasts up to five months on a full charge. Those tests assume around 20 event videos each eight seconds daily.
In real life the results can differ a lot. With heavy usage, one estimates it at three months and ten days before recharge. Some users report heavy problems, where the Battery empties in only five to six days.
Cool weather also boosts the usage, especially in temperatures under -10 degrees Fahrenheit.
The charge lasts around four hours using a 5V 2A Type-C charger. Before setup one should fully charge it.
One can choose between usage of the rechargeable Battery or fixed wiring too existing doorbell cables in 8-24V and 5-40 VA. The fixed wiring works as continuous charge and keeps the Battery up. In some cases, turning on the energy saving mode in fixed state, the Battery stayed around 90 percent during a whole year.
The detection distance overnight is shorter than the 25 feet in daytime, especially in darkness. The PIR sensors start recording on motion, so passing cars or nearby creatures can create unnecessary alerts and boost the Battery costs.
The setup happens quickly and without issues. No special knowledge is needed. It supports dual band Wi-Fi in 5 GHz and 2.4 GHz.
Good signal outside helps reliable connection. It allows both cloud storage and local video storage.
A big improvement is the support for mechanical bells. The wired original model did not work with existing mechanical bells, but the Battery version does that. Even so there are downsides, like video delay and limited fit with smart homes.
The body is verycompact, which partially explains the limited Battery size.
