Camera systems for your doorbell
This may not seem like the best safety device that you could get, but given the fact that a lot of family members are afraid that someone could walk into the homes of their retired parents or relatives, it is actually a great device to consider investing in.
Not only are they fairly inexpensive, but the doorbell camera systems are extremely useful even if you do not want to invest a lot of money into a security system for your home. They are also great because they can be installed in apartments as well, so you can feel protected everywhere.
Devices like the Ring and NEST camera systems will let you talk and even see anyone who comes to your door through the HD recording, and you will be able to know who came to your door in an instant. Not only will this protect you from people who would want to take advantage of a senior, but you will also be able to keep a close eye on your packages if the mailman just leaves them on your doorstep, as they offer 24/7 streaming and recording!
