Comparing analog cameras with IP cameras
These comparisons will allow you to determine if a security camera is right fit for your needs. An analog camera is a CCTV system that uses older technology. It transmits video via a cable to VCRs and DVRs. All IP cameras can transmit signals via cable to other . These signals can be saved to the network. Today’s security cameras often combine digital and analog components.
Video quality
Analog cameras are less reliable that IP camera. They provide more video site options, such as a larger or smaller field view and greater zoom-in capabilities. They can also transmit digital impulses and provide additional details. They can recognize faces and identify license plates numbers better than their human counterparts.
Although analog cameras are less reliable than IP cameras, their quality is still better than IP cameras. An analog camera can’t zoom as far as IP cameras, and is less flexible. Zooming in can make analog images grainier and less sharp. This is not the same as what you see on TV police shows. If you zoom in on an analog camera, it won’t help identify perpetrators.
Resolution
Digital cameras can produce images six- to twenty-fold more detailed than analog cameras. Sharp images can be created at higher resolutions than an analog camera (which ranges between 420 and 700).
IP cameras can have resolutions of up to 5 Megapixels (256x2096 pixels). They can also transmit compressed encoded data. This allows you zoom in to see more detail and also allows you to capture larger areas.
Transmission media
An analog camera can be wired with coax cable. You can wire them over coax cable, or with twisted pair cables. This will result in lower resolution.
Capabilities of POE (Power over Internet)
The advantage of IP cameras is their ability to be powered using twisted pair Ethernet cables. This eliminates the need to run wires.
Wireless
You can use wireless IP camera network connections in places where it is too expensive or difficult to run cable. Wireless can be used in areas where cable is not possible.
Distance
An analog camera can transmit video via coax and twisted-pair cables up to 1.5km. Analog transmissions can lose clarity as distance increases.
IP cameras transmit digital video via Ethernet cables up 100m. IP networks allow for unrestricted distances. The images can be transmitted digitally so they retain their clarity even over long distances.
Management and intelligence
IP cameras enable remote management and network intelligence. Multiple IP cameras can simultaneously access multiple recipients. Both parts and images can be streamed simultaneously. It is another job to send messages to recipients.
Installation is easy
Analog cameras require more cabling than IP cameras. To control zoom, pan, tilt, and other functions, separate cables are needed. A second cable might be needed if audio is being used. Three cables may be required for one analog camera: power, audio, and video.
One cable can transmit power, video and audio signals to IP cameras.
Security
Analog cameras are more susceptible to security breaches because feeds can be physically intercepted, taps taken, or recording devices taken. Analog video feeds cannot be encrypted.
IP cameras make it very difficult to intercept data. They can compress and encrypt data prior to it being sent over the Internet.
Reliability
Analog security cameras have been around for more than 50 years and are trusted.
Because of data encryption and compression, IP systems are built in reliability. Although they can reduce outages, backup systems can be just as reliable and effective as the network.
Expand-ability
Because IP cameras do not require as much cabling they can be more flexible and scale up quickly. Extensions and converters can be used to extend your existing cabling infrastructure to migrate IP cameras.
Prices
Although IP cameras are more expensive than analog cameras due to the higher cost of the cameras, prices have been falling steadily. A lower cost of recording equipment and labor might make an IP-camera system more affordable than expected.
Connecting IP cameras to existing cabling infrastructure using media converters and extenders is a great way to cut costs.
