Comparing Analog And IP CCTV Cameras. In this modern age, technology is ever evolving — and this is especially true regarding CCTV cameras. CCTV cameras are part of any sound security system. Today, two types are widely used: analog cameras and IP cameras.
Here, we’ll give you a rundown of the significant differences between these two types so you can choose the one that works best for your surveillance needs.
The main difference between analog and IP cameras is how videos are recorded, sent, and stored.
Analog cameras are the earlier CCTV models and send footage the old-fashioned way. It records images and sends the signal via a coaxial cable to a DVR (Digital Video Recorder). This DVR then converts the images to digital signals, which are compressed and stored on a hard drive. The DVR must be connected to a monitor or TV to view the footage.
IP (Internet Protocol) cameras are more advanced and work by digitally recording videos. Instead of using a DVR to convert images like analog cameras, IP cameras send and store videos via a computer network.
Generally, IP cameras, which are more digitally advanced, are better regarding image quality.
IP cameras have a much wider field of view and offer a range of zoom-in settings. Since the footage is transmitted digitally, the images have more detail, meaning better facial recognition.
Analog cameras, on the other hand, have lesser image quality and limited zoom-in settings. The images also tend to be grainier because of the narrow field of view.
But analog cameras compensate for this by performing well in low-light areas and at night. There are also high-definition (HD) analog cameras today that have greatly improved image and video quality.
Analog cameras have limited resolution, with most models having a standard solution of 0.4 megapixels.
On the other hand, IP cameras provide higher resolutions that range between 1.3 to 5 megapixels. The downside is that a higher resolution means they take up a lot of storage space.
Analog cameras can send videos via coax cable up to a distance of up to 300 meters away. The downside is that the farther the space, the more the footage becomes grainier and loses clarity.
IP cameras, on the other hand, send videos digitally via computer networks, so there is no limit regarding distance covered as long as there is a network connection. And since videos are in digital format, they maintain their original resolution and clarity regardless of the space.
Analog cameras are significantly cheaper, which is a significant advantage when installing several cameras.
IP cameras are more technologically advanced and, therefore, more expensive. They also require more bandwidth for video transfer over a network.
IP cameras are easier to set up because they require less wiring. There is no need to invest in new cabling since they connect to an existing computer network. And with Power over Ethernet (POE), a power outlet near the camera is no longer needed.
Installing analog cameras, however, requires a lot more cabling. They typically require separate cables for power, audio, video, and even more for tilting and zooming.
Analog cameras lack wireless options. Since they need to be connected to the DVR, the cameras must be near the device. As a result, you have more limited choices on where you can put your cameras.
On the other hand, IP cameras don’t need hardwiring since they’re connected wirelessly to a computer network. Sometimes they can even operate with solar panels and battery backup, so they don’t need wired electricity.
Analog cameras lack data encryption technology, making the footage susceptible to digital invaders who can easily intercept the feed. On the other hand, IP cameras offer better security since video footage is encrypted and compressed before transmission.
Choosing between analog and IP cameras will depend solely on your particular needs. There are advantages and disadvantages to both types of cameras.
