A:AnswerNot sure what you mean by blurry but while the camera does record 24/7, it only records in high resolution during motion events. The memory would fill too quickly otherwise.
A:AnswerNo, this one has a plug to it. Maybe consider the door bell that they offer. The only bad thing about the door bell is that it don't continuously record. They also have cameras that can run by battery, with the solar panel.
A:AnswerThis camera records in either 1080p or 2k footage. The resolution of your phone will not affect the way it works or your ability to review footage on the app.
A:AnswerI believe you are limited to 32GB. I bought some bigger cards for the cameras and was told they could not be formatted. Sandisk is the brand I use.
A:AnswerAccording to eufy support, "We recommend using a class 10 high-quality microSD card; the largest card our eufySecurity video devices support is a 128 GB microSD card."
A:AnswerI'm sorry but as an owner if this camera I do not have the knowledge to determine if these memory cards are workable for the camera or not. I would have to consult with a sales associate at Best Buy. Each store should be able to answer that for you.
