Analog Cameras and Bag Phones
10-15 years ago, I was using a voice pager to receive messages telling me to call the office, home, and so on. Then I’d have to try and find a pay phone to use to make that call. When I got my first bag phone, I was in heaven. It was the most convenient thing I’d ever seen. Of course, I only had 150 minutes on my plan, so you’d better talk fast, buddy. The bag phone changed to a handheld phone, then to a flip phone…
Now, we can get emails, text, talk, download an app, surf the web and use GPS to get to our destination. All from one device. What I’m getting at here is this: we have come a long way in technology. Given enough time, cutting-edge will always become old-fashioned.
You can see evidence of this in the way cable companies are transitioning their stations to High Definition (HD). Back in the bag phone days, the analog version of broadcasting was the industry standard. Nowadays, most of us have seen something broadcast in HD. I think we can all see the differences in the two pictures.
In the same way that the technology behind TV broadcasts is changing, so is the technology behind CCTV systems. Analog cameras on a digital video recorder (DVR) used to be industry standard. Now, CCTV systems are transitioning to IP camera technology.
So what’s the difference?
- With IP cameras, you can zoom in after video has been recorded and not be as pixellated. Analog cameras offer a zoom option, but the image quality suffers.
- Cameras can get power from the switch. This means power comes through the ethernet cable and not from an adapter, which cuts down on wiring. Analog cameras require both a Coaxial cable and an additional power supply.
- Footage captured by an IP camera can be viewed remotely. Live video from any camera can be viewed from any computer, anywhere, and also from some mobile devices. Footage captured by analog cameras must be viewed at the DVR.
The most impressive difference? Take a look. The simple truth is that IP cameras allow you to see so much more. Sometimes switching from an analog TV broadcast to an HD broadcast feels like your eyes are finally open. Switching from an analog camera to an IP camera can have the same effect.
