What the Difference between IP Cameras and CCTV Cameras ?


Many have speculated that the area of CCTV (closed-circuit television) cameras is coming to an end. These multi-purpose video cassette recorders and all their T-160 tapes are quickly being replaced by capture cards, embedded processors, codec, and more advanced devices. IP cameras have played a major role in phasing out CCTV cameras, as they offer many of the same benefits, yet provide much more. What’s the difference? Plenty! Let’s delve into some of the details and find out how IP cameras tower over their analog CCTV counterparts.

Remote Viewing

The major benefit of IP cameras is the luxury to view live video via the internet from any location in the world. While CCTV cameras can enable viewing over the internet, they require additional software and hardware components to function properly. An IP camera is integrated with all the necessary tools and doesn’t require any additional installations. Some of the newer models are even able to view live video on a cell phone or other mobile device over a 3G network.

Remote Recording

The primary function of a surveillance camera is to monitor a certain area when security and staff are unable to do so. While it serves its purpose for the most part, CCTV cameras are susceptible to security breaches, and the tapes they contain can be stolen. IP cameras enable recording to remote locations, which virtually eliminates such a scenario. Even if security is breached, the intruder will not be able to steal the tape or recording device because it is physically stationed at a remote location.

Wireless Capability

Because IP cameras leverage standard IP (Internet Protocol) networks, many of them are available in wireless variations to provide the ultimate in portability. All the device requires is a single cable for a power supply, which results in less work when installing the camera in the recording location.

Video Analytic

More IP cameras are being implemented with video analytics to provide advanced tracking and motion detection capability. This technology is so sophisticated that it has the ability to distinguish between the movement of a person, a car driving down the road, or a tree merely swaying in the wind.

More Advancements to Come

CCTV cameras aren’t completely obsolete, but are light-years behind in comparison to IP cameras. IP technology allows individuals and businesses to effectively monitor their home or office premises with little to no security risks. Evolving rapidly, it’s almost certain that you will be able to do much more with an IP camera in the very near future.

Using Wireless Internet CCTV to Detect Fire and Flood

Wireless internet CCTV cameras are more than just CCTV cameras. These cameras allow you to see your property from anywhere, over the internet.  More than this, they can be used to alert you not only to movement within the camera view, but also to emergencies like fire and flood as this article explains.
Most internet CCTV cameras have the ability to raise the alarm when motion is detected within the camera’s field of vision, giving you the chance to log in over the internet and see what’s going on.  However, many of the good quality cameras can raise the alarm when other events happen in the vicinity.  They do this by “listening” for signals that are sent from sensors when conditions change, for example in those extreme cases when there is a fire or flood, and by sending text messages or email alerts when such signals are received.
The type of sensor you use will depend on the type of event you want to protect against.  You could buy a heat sensor and set it to trigger when the temperature exceeds a certain level.  This could be used to detect a room becoming too hot, a freezer breaking down or a refrigerator getting too warm inside, for example.  You would use a moisture sensor to protect against flood.  This could be placed in a basement or near a washing machine.  Normal industry-standard sensors will work with all good makes of camera, but you should check the trigger voltage and wattage of each to make sure.  In all cases the sensor will send a change in voltage to the camera so that it can take action, as the next section explains.
To attach sensors to your camera, it needs to have a so-called digital input port.  Most of the reputable makes of internet CCTV camera have one.  Two wires are attached to connectors that make up the physical exterior of the port, and these wires run to the sensor.  The camera is programmed to recognize a change in voltage at its input port caused by a signal from the sensor, and to act upon it immediately.  Typically it will send you an email and also an instant SMS text message to your mobile phone or as many mobile phones as you choose.  You can then log in over the internet to see what is going on, and if necessary call the emergency services, all within seconds of your sensor detecting a problem.  Of course, it takes some technical work to get your camera working in this way, and you will need external service providers to handle things like sending SMS text messages.  If you don’t like the thought of setting this up yourself, I always advise getting a pre-configured camera and monitoring service from an internet CCTV provider.
Using wireless internet CCTV cameras in this way really broadens their role.  Seeing your home from wherever you are is just the start.  Attaching sensors and programming the cameras to act upon their alerts turns your camera into an all-round automated property monitoring system that keeps you informed about any problem in your property, within seconds of that problem arising.
