Wireless security camera buying guide
Using the internet to keep an eye on your home
A wireless security camera can keep watch while you're away
It's not always practical to ask the neighbours to watch the house while you're on holiday. An alternative can be to install a wireless security camera and use technology and the internet to keep an eye on things yourself.

Keep an eye on your home from your phone or tablet
A wireless security camera is a lot like a webcam, except it can sit anywhere in your house and connects to your local wireless network as well as the internet. With this kind of camera, you can keep watch on your house from around the corner or from another country via a computer, smartphone or tablet, helping to ensure peace of mind.
Wireless security cameras work through your home internet connection, taking still pictures and/or video (usually 30 seconds or less) when they detect movement. They will notify you immediately via SMS or email when there's footage to be viewed. Some of them can even upload pictures and video instantly to the cloud for safekeeping and immediate viewing.
Once largely disregarded because they were too technical for the average user to set up, wireless security cameras have come a long way. Most now come with software that allows you to access photos and videos through your smartphone, as well as a web-connected computer, no matter where you are in the world. Setting them up takes just a few minutes and just about anybody can do it.
One of the benefits of wireless security cameras is that they're generally small and unobtrusive. Many connect to your home network so you can place them just about anywhere in the home without having ethernet cable running all over the place. Some even run on batteries, to make them totally wireless – you'll see them marketed as "wire-free" cameras.
But most wireless units will need access to a power point. It's generally easier to do this than to have an ethernet point, or a long run of unsightly blue ethernet cable, unless your home is properly wired for ethernet through skirting boards (though relatively few homes are).
If you do have the opportunity to use ethernet cabling, many Wi-Fi cameras have an ethernet port, so you can plug in directly. While Wi-Fi is more convenient, wired ethernet is still faster and generally provides a more stable network connection. You may want to look for a camera that has power over ethernet (PoE) as a feature, as this will let you power the camera from the same ethernet cable used to carry data, avoiding the need for both ethernet and mains power cables to the camera (though you'll need a PoE connection box).
Your camera should come with an ethernet cable (where applicable), power supply, antenna, wall mount (including screws) and set-up instructions. Here are some points to bear in mind when choosing your camera.
- Resolution: Is it high-definition or lower? This will affect picture quality and upload speeds.
- Night vision: Does it have an infrared LED for night vision?
- Microphone: Useful in particular when the camera is used as a baby monitor.
- Speaker: So that you can talk through it (again, useful for baby monitor use).
- Movement: Can it pan, tilt and zoom via remote control?
- Storage: Is there built-in storage (memory card slot) for saving recordings locally?
- Power: Does it run on batteries and if so will it take rechargeable batteries? Or does it need to be plugged into mains power (if so, how long is the power cable?). Or can it take power over ethernet cabling (PoE)?
- Networking: Can it work via ethernet cable or is it restricted to Wi-Fi?
- Mounting: Can it be fixed to a wall or does it just sit on a flat surface?
- Expandability: Can the system be expanded (and to what extent) with additional cameras and sensors for windows, doors and motion detection?
- Monitoring: How do you view the video – via web browser or mobile app?
- Remote control or just viewing?
- Motion detection: What capabilities and restrictions are there?
- Alerts: Via email or SMS? For sound as well as movement?
- Image clarity: Daytime and low-light quality.
- Adjustable frame rates: This can be useful for varying the quality and file sizes of recording and streaming
- Extra service costs: What is required for using the camera for streaming? Are subscriptions needed for storing and accessing videos remotely?
While most consumer-level wireless security cameras are very handy for casual monitoring, if you're serious about security you'll want to check out higher quality systems, which are generally wired into your home and need to be installed by a professional. If you're using your wireless security camera for even casual home monitoring for security, good image quality is important. If it catches an intruder in the act, you're going to want to be able to identify them. Unfortunately, there's no simple way to tell from the box how good the quality will be.Night vision
Many cameras also offer night vision, which is particularly useful for security monitoring because it can pick up images in very low-light conditions and even in complete darkness, which is often how the house is when you're not there. However, the quality of images can vary greatly and the distance to the camera is important – the closer the better. Good quality night vision can make all the difference.
Having the ability to view your camera's footage remotely is an important feature, given that you won't have access to your home computer if you're away on holiday. Here are remote access features to look for:
- Email and SMS/MMS alerts: Can you set the camera to send email/SMS/MMS alerts when they're triggered? Can you automatically attach a recorded image to the alert?
- Mobile access: You can't beat the convenience of being able to look into your home remotely via your smartphone or tablet. Most cameras have software for iOS (iPhones) and/or Android OS, but make sure it's compatible with your system.
- Web access: Is the wireless security camera video feed accessible online, through a computer that's not part of your home network?
Some wireless security cameras will store recorded footage on a flash memory card or an external storage drive connected to the camera. Some models offer better security by taking the images offsite immediately, saving them straight to the cloud (internet-based remote storage). Either way, you'll want to make sure you have a way of keeping any important videos and photos. Here's what to consider:
- Cloud storage: Some wireless security cameras may provide the cloud storage service for free, but with limited space and for a limited time. Others will provide more, but charge a subscription fee. Alternatively, you may be able to save your files to your own cloud service, like Dropbox for example. Check if the camera software can be configured to connect to a remote storage file server, and whether your particular cloud service will allow it.
- Memory card: Does the device have memory card storage for recordings? This can be handy, as the images will be saved on the card in the camera for easy access, and avoids having to configure and possibly pay for cloud storage. But there's the risk that the card or camera itself may be stolen.
- PC storage: Can you save and store pictures/video to your computer using the PC program or through the web? This gives you much more storage capacity, but requires that your computer be left turned on. And there's the danger that the computer itself could be stolen.
- Smartphone/tablet storage: Can you save and store pictures/video to your phone or tablet using the camera's mobile app? If you can view images and video through your mobile device, can you download them and save them to it?
- Pan, tilt and zoom: There's a big advantage in having remote control of the camera to zoom in and make it look around the room with up/down and sideways movement. Models with this ability will generally cost more.
- Motion sensing: You want a camera that can be set to detect motion and automatically take pictures and video and send alerts. Other considerations include whether you can set time slots for motion detection to be active, and if you can adjust its sensitivity.
- Audio link: Some cameras have one-way or two-way audio communication via the camera.
Wireless security cameras range in price from around $50 to $500, depending on features like remote control, night vision, Wi-Fi, megapixel rating and lens quality.
