Alarm systems and IP televigilance vs. analogous

IP surveillance camera

As technology advances, alarm and remote monitoring systems are becoming more and more innovative. However, when it comes to security There are those who stay true to traditional analog systemswhile others prefer to be at the forefront of the modern lifestyle.

If you still can’t decide, we have an excellent one here Comparison between alarm system and IP video surveillance with analogso that you know their differences and can choose the option that best suits your needs.

Differences between IP and analog systems

At this point we are going to explain the main differences between alarm systems and remote surveillance or video surveillance.

picture quality

Video surveillance cameras for security systems IP alarms have a higher resolution and video quality than analog they also offer more display options, a bigger and better zoom system and because they are digital, IPs can be used for face recognition.

In the case of the analog camerasalthough they are of lower quality, works best in dimly lit locations. However, like IPs, they cannot be used for face detection because the zoom is not sharp and the image is distorted.


Another important aspect is the resolution, which in the specific case of IP is up to 20 times higher than analog, since in the latter their resolution ranges from 420 to 700 pixels, while in the IP you can get incredible sharpness as they have areas from 1.3 to 5 megapixels.

In many cases The number of megapixels in the IP also affects the area or width of the image You can capture what is higher compared to analog.


There is also a distinction between IP and analog systems based on the medium with which they transmit their videos Analogs usually use coaxial cables or sometimes short-range, short-range wireless systemsWhile IP uses coaxial cable, twisted pair, or wireless networks.

PoE power

The IP video surveillance cameras can use twisted pair ethernet cables Without the need for a power supply through electrical current, however, the analog ones cannot be operated with PoE and require electrical power to function.

Wireless connection

In the case of the IPs can use wireless systems for its operation and save the wiring task; while analogs require connection, generally through point-to-point cabling.


Although the quality decreases with increasing distance Analog can travel up to 1.5 kilometers with twisted pair and up to 0.3 kilometers with coaxial cable.

In the case of IP, they can cover 0.1 kilometers of twisted pair cable over Ethernet and unlimited distances over IP networks without affecting the picture quality in the video.


Although today both IP and analog cameras have been used for alarm and video surveillance systemsThe IP have messaging systems and also remote assistance. This technology is normally used by Movistar Prosegur Alarmas to send an alert when movement is detected. This is an advantage that analog technology does not offer.


The analog ones are generally more complicated to install as they require more cables, while the IP can perform all the required functions over a single cable.


Another important aspect to consider is the ability of each individual to provide security. With analog cameras, the videos can be changed because they do not have an encryption system and have more physical structures, cables and devices that can be cut, stolen or modified.

For his part, IPs usually have extreme data protection and encryption systems in place too extreme, which enables them to offer more security than analog.


Some people often believe that IP is much more expensive than analog The prices are usually quite competitive. This is due to the fact that, on the one hand, IPs use more technology and this affects the increase in costs, but in many cases the competition in the market leads to a decrease.

For his part, Analog can be cheaper in terms of technology useHowever, the number of cables and connecting devices required can add to these costs.

In both cases, both the IP system and the analog system have complemented the alarm systems over the years, making them an integral part of achieving the goal of keeping homes and businesses safe.

Which system should I choose?

Again the system you choose It depends directly on your needs and the use you want to give it.

Compare both examples with your current situation and you can determine the most compatible system. Another recommendation is thatYou are trying to turn to experts for a proper installation of the system you have chosen, especially if you don’t have a lot of knowledge about it.
