Types of Home CCTV Systems

Posted by Discount Security Store on 3/14/2015

If you are in the market for a home CCTV system there are a number of factors to consider in making the best choice.  Below is an overview of some of the characteristics and differences of home CCTV systems to help you make your selection.

Wired home CCTV systems

These are the most common and cheapest type of camera, where a wire plugs directly from the camera to the monitor. The downside is that the wires, including extension cables and connectors, can be difficult to lay.

Wireless home CCTV systems

Images can be transmitted using analogue or digital technology. Digital cameras are generally higher quality but more expensive. Wireless systems can suffer from interference from devices such as routers, cordless phones and microwaves, and can be blocked by heavy masonry or metal objects. Your filming may also be interrupted if your Internet connection is lost. 

IP CCTV systems

These are cameras that use your network or internet portal to send images to your computer's router, allowing you to access the footage over the internet from remote locations.

Outdoor home CCTV cameras

If you’re using CCTV cameras outside, make sure they’re weatherproof – an IP (International Protection) rating of 66 is recommended. Wireless cameras are available, but you’ll still have to run a cable to a power source. Position cameras where they can’t be tampered with, but can be accessed for maintenance and cleaning. You can by vandal-proofing cameras, but these tend to cost more.

Indoor home CCTV cameras

Indoor CCTV cameras come in three types: wired, wireless and power line networked (these plug into your electrical sockets and transmit images to a storage device). Wireless cameras are not recommended inside the home unless the signal can be encrypted, as anyone within range and using a suitable receiver would be able to view the images.
