IP cameras transmit video by using open internet protocols and standards.
There are some proprietary methods for sending video that only the manufacturer of the camera can decode.
Those are not IP cameras.
True IP cameras can be used with almost any computer monitoring system regardless of manufacturer.
According to Wikipedia, Axis Communications created the first IP cameras in 1996.
Those IP cameras used Linux as their base operating system.
The company also released an open architecture for their IP cameras and encouraged third-party vendors to develop complimentary software.
This culminated in the exponential growth of the market for IP cameras.
Some advantages of IP cameras over CCTV cameras are:
- Overall security system costs are lower because specialized proprietary equipment isn't as necessary.
- IP cameras provide you with more choices for video recording hardware and software because of their open-platform.
- Cabling for IP cameras is much cheaper and easier, and can use existing internet ready installations.
- IP cameras won't limit you to traditional video standards like NTSC, PAL and SECAM.
- You can transmit comments for PTZ (pan, tilt, zoom) to IP cameras on the same cable.
- IP cameras can be multi-functional, and can even send email.
- Support for different streaming media and compression formats give IP cameras an advantage with data storage.
- New embedded intelligent video motion detectors are built into some IP cameras with facial or shape recognition.
- IP cameras are essentially future-proof. They can always be updated with newer technology.
There are many vendors for IP cameras.
One major vendor of IP cameras is Sony.
There is an entire section of our site dedicated to that.
When selecting the best IP cameras for your needs, you'll also need to consider if you are using an enterprise solution.
The key here is the scale of your surveillance system.
IE, are you securing a casino or an 800 sq foot home?
There's a difference, and we here at XJA Systems & Consulting can help you determine what's best for you.
