WIRELESS CAMERAS – ARE THEY ANY GOOD?
With the emergence of wireless cameras on the market, many people wonder why they cannot just use them everywhere? It’s a good question and there are definite pros and cons to wireless cameras.
First – let’s make a distinction on the word “wireless” itself. With wireless cameras there are two signals which must feed the camera:
- The video signal itself
Some wireless cameras still use a cable for power (i.e., they need to be plugged into the wall), but are still termed wireless because they use WiFi for the video signal. There are also some wireless cameras that use batteries for power so they truly are absent any wires at all.
Okay, now that we have that straight, the question is: How good are they and where is best to utilize them? In either of our cases above, the video signal is communicated through WiFi which is good when reasonably close to your router or at least an access point (AP). They are best used inside in various rooms about the home. Also known as “drop cams,” they can record to a SIM card or a Cloud service offered by the manufacturer for a subscription fee.
All wireless devices are subject to radio frequency (RF) interference and the signals degrade with distance so this is why they may not work well outdoors. There are some cases when positioned near the home (and particularly near the router or AP) that they can do the job. A professional installation company, like LiveSmart Technologies, can help you understand when you can use wireless cameras outside and when you should opt for wired cameras.
A simple rule of thumb: Use wired cameras when you can and wireless when you have to. Be sure they are within range of the router or AP and can withstand the weather if placed outdoors. As always, we are here to help you with the decision and process.
