CCTV Analog Cameras vs. IP Camera Systems

Older CCTV systems use analog cameras that send video over DVRs or VCRs. On the other hand, IP cameras are more advanced and send signals over cable for storing.

If you have an analog CCTV camera and you are wondering whether you should replace it with an IP camera, here are some of the things you should know before doing that.

1. Video Quality

IP cameras come with higher video quality compared to analog ones and they offer better zoom capabilities.

Moreover, because IP cameras transmit digital signals, they provide better video detail, which makes them ideal for detecting car plate numbers and facial recognition.

Now, although the overall quality of analog cameras is nothing to write home about, they do perform better under low light conditions. These cameras also have a limited site range and do not offer as good zoom-in clarity as IP cameras.

With analog security cameras, if you zoom in on images, what you get are degraded and grainier images. That means that you will hardly ever deduce any information from the images.

2. Resolution

Usually, digital cameras come with resolutions that are 6 to 20 higher compared to analog computers. The thing is that analog camera resolutions are limited to the NTSC/PAL standard that offers.

On the other hand, IP camera resolution ranges between 1.3 to 5 megapixels. With this, you get to cover a wider and far viewing area as well as get more details from images even when they are zoomed.

3. Transmission Media

Conventional cameras use coax cable and they can operate with wireless connections or over twisted-pair cable but yield less resolution.

IP cameras work over coax, twisted-pair cable, and with wireless connections as well. The main difference here is that they produce a greater resolution.

4. PoE Capabilities

One of the main benefits of using IP cameras is that they can operate using twisted-pair cable hence eliminating the risk of overrunning electrical wire. Analog cameras cannot be powered the same way so there is a risk of overrunning electrical wire.

5. Wireless Capabilities

When it is too expensive or difficult to run cable, IP camera wireless network connections can offer a practical solution.

Wireless also comes in handy in buildings where it is impossible or impractical to run cable such as in older buildings.

7. Manageability and Intelligence

IP cameras allow for remote manageability and network intelligence. This means that they can stream different sections of images to several recipients at the same time.

They also perform extra tasks such as sending alerts when motion is detected. This is a functionality that you will not get with analog computers.

8. Ease of Installation

Perhaps you do not know this but analog cameras require a lot more cabling compared to IP cameras. The former need separate cables for controlling z0oom, tilt, and pan functions.

In case you need audio functionality, you will need a separate cable for it as well. IP cameras on the other hand can accept control signals, PTZ control, audio, video, and power in a single cable.

9. Security

Analog surveillance cameras are extremely susceptible to security breaches seeing as their recording devices like tapes can be stolen and their feeds physically intercepted. It gets worse because analog video feeds are not encoded.

Conversely, are harder to intercept and this is because they compress and encrypt data before transmitting it to the internet.

10. Reliability

Analog surveillance cameras have been in operation for more than 50 years and with that comes a long history of dependability.

Now, although IP camera systems come with in-built reliability owing to their data compressing and encrypting abilities, their reliability depends on the network.

11. Expandability

Remember that the cabling requirements for IP cameras are less complex. This is important because it means that the cameras offer more scalability and expandability. Nevertheless, you can still use existing cabling infrastructure when migrating from analog to IP cameras using extenders and converters.

12. Analog Camera vs. IP Camera Costs

As you may have imagined, IP camera systems are costlier than analog ones and this has a lot to do with the technology used in the making as well as the level of functionality they come with.

That said, the cost of IP cameras continues to drop and the overall cost of maintaining them is lower as well seeing, as there will be lower costs for labor, recording equipment, and cabling.

Final Thoughts

Ideally, you should move with the times and when it comes to surveillance cameras, you would prefer IP camera systems to analog cameras.

With IP cameras, you get better functionality and that is enough reason for you to pick them instead of outdated analog systems.
