Battery-powered cameras that use WiFi to transmit their footage are the easiest to install, since there’s much less equipment and wiring to deal with. This is also the best option if you only need 1 or 2 cameras instead of a larger system
• The footage from these cameras is also wirelessly stored, usually in some kind of cloud. This means you don’t have to worry about setting up a DVR storage device.
• The major downside of wireless cameras is that they require consistently strong WiFi in order to work properly. Because they’re battery-operated, their batteries also need to be replaced from time to time.

Although they’re a bit more complicated to install, cameras that use wiring to attach to a power source and to their storage device are more reliable than wireless cameras. These are best for creating a security camera system somewhere with good wiring infrastructure, such as a home or office building
• Note that wired cameras tend to be more expensive than wireless cameras, given the extra equipment. However, with DVR storage, you’re also able to avoid any subscription fees that may be required for storing footage wirelessly in a cloud.
• Because they need to be installed near an outlet or other power source, wired cameras aren’t as versatile as wireless cameras when it comes to where they can be installed.

If you don’t plan to have someone constantly monitoring the video feed from your cameras, receiving notifications when the camera detects motion is the only way to know about security events as they’re happening. These alerts can usually be sent to both you and to a professional monitoring service
• This service will contact you regarding the security event and will alert law enforcement if necessary.
• Most camera systems that include notifications will also be accessible via a smartphone app that you can use to monitor the video feed from anywhere.

Otherwise, if the camera is pointed toward a location without any lighting, it won’t be able to pick up any activity that goes on there. This is especially important if you plan to install your security cameras outdoors
• Note that cameras with night vision may be rendered ineffective by bright lights, so be sure not to install them near a street lamp or other source of light

The larger the field of view, the more your camera will be able to pick up. For best results, go with a camera with either a 180-degree lens or with pan and tilt functionality
