If yours is like most American households, you probably have a drawer with old smartphones collecting dust because you upgraded to a newer model.
These older smartphones pack quite a bit of processing power, and decent cameras. So a number of enterprising app developers have created an assortment of options for repurposing them as webcams.
Your specific needs will have a lot to do with which option makes the most sense for you.
On paper, this seems to be a great way to use that old tech, but if you鈥檙e serious about security, you need to understand the limitations.
Logistical considerations
One of the first things you need to think about is providing power to the old smartphone, so you need聽to use it somewhere聽near a power outlet.
The next thing to test is the strength of the聽WiFi signal where you plan to place it, since that will be the only way it can connect.
You’ll also need to think about some form of cradle, tripod or stand, so you can point the phone where you want to monitor.
Live video vs. monitoring
Getting an old phone setup for transmitting a live video stream is pretty simple, but if you鈥檙e interested in a security system, you鈥檒l want more.
Most people want a system that watches for motion and alerts you with a text or e-mail message so you can pop on and see what鈥檚 happening as it’s happening.
What鈥檚 the goal?
Some apps only take pictures, while others record video; some include sound, while others don’t.
Some offer two way communication and can sound聽alarms when they detect motion, which may or may not be important for your situation (baby monitor vs. intruder detection).
Technical limitations
Most security-focused webcams these days include night vision, which your old smartphone won’t聽be capable of providing — so the lighting becomes critical.
The video quality may also be less than desirable, depending upon the lighting and the distance you鈥檙e trying to cover聽(Tip: Always use the back-facing camera; it鈥檚 always higher resolution).听
You鈥檙e also at the mercy of your Wi-Fi connection and won鈥檛 necessarily know when it goes down if you鈥檙e not home.听 If you鈥檙e serious about security, a wired webcam is always better.
Recording Events
Guess why so many of the apps that offer this service are free?聽 They know that most people will want to be able to record and playback events, so just about all of them have a monthly fee depending on how long the videos are available or how much footage you want to store.
I鈥檝e found the apps from聽, 听补苍诲 聽easy to set up and get running.
Some allow you to extend the system beyond your phone through services such as聽 or .
I wouldn’t consider this solution the best security system, but since they’re free to try, you can decide for yourself.
