Trinity Systems offers modern video surveillance solutions to its customers. We mainly focus on the implementation of systems based on IP cameras and IP environment. This commitment of our company is based on the obvious advantages that modern IP technology offers over analog systems, which have experienced the peak of their development in recent years, but whose features lag behind the quality and capabilities of modern systems.

Our suppliers who offer devices for this type of solutions are:

– TP Link
– Vivotek
as well as suppliers whose products we use for an integrated solution:
– Draka
- Unikom and many more.

In the following text we will first look at the advantages that the new digital systems offer over analog ones, and then we will make a brief overview of the devices that we consider the most popular for this type of system solution.
Of course, our company also offers devices and solutions that are not described in the following text in the interest of space. Therefore, if you are interested in products of this type, feel free to contact us so that we can offer you an appropriate solution.
The advantage of IP over analog CCTV cameras is obvious above all in terms of better picture quality. Finally, the purpose of the CCTV system is to clearly record everything that happens. Have you ever heard of someone being caught and identified committing an illegal act by a system with analog cameras? Most often, the image of such systems is blurred and useless to the police. The fact is that traditional CCTV cameras have reached the end of their evolution and can not compete with the high resolution of IP cameras.
Megapixel vs Analog

In the first image, both cameras are adjusted to cover the same field of view. From this it can be concluded that in that case, the IP camera gives 3 times larger images, ie much more detail than the analog one. In the second image, both cameras are set to show an image with the same quality of detail. In that case it can be noticed that the IP camera covers a 3 times larger area than the analog camera.

Imagine what the difference in images would look like if a 10 Megapixel IP camera was used! This confirms the fact that analog cameras are far outclassed.

Image clarity when supervising moving objects

Even with the highest resolution analog cameras available, the image clarity when shooting moving objects such as a man running or a moving car is a major problem.
This is due to the fact that the analog systems even when recording on a DVR, integrates to create an image, ie the even and odd lines of the image are displayed as two images one after the other which creates blur. The difference from a captured image with a digital and analog camera is shown in the images above.
Network video server vs. DVR
Many claim that the DVR system recording features are the same as the Network Video Server. Although the quality of the recording on the DVR, because the recording is digital, is much better than the VHS-based systems, still because the signal is not digital, they cannot be classified as IP. IP-based video server has many features that are significantly better than the DVR system: it is much simpler, easy to use by the user, has significantly longer recording time, has much more advanced search capabilities, WEB-based monitoring and advanced control access.

In summary, other advantages of IP based over analog video surveillance systems are as follows:

1) In systems based on IP cameras networking is simpler, existing IP networks can be used, and thus, it is more flexible (it is easier to move to another place) and cheaper. In many cases this price offsets the slightly higher cost of IP cameras.

2) Due to the way the signal is transmitted, which is digital in IP cameras, they are much more resistant to noise, bromine and various electromagnetic influences compared to analog transmission, in which such influences can significantly impair the image quality. With IP cameras, transmission encryption is simple and long-distance transmission is easily solvable.

3) IP cameras mostly have many more functions and capabilities that are difficult to implement with analog cameras:

a) Day and Night shooting mode (Day / night cameras are simpler and better suited than analog),

b) Motion sensors that can locally activate a function,

c) Direct control and digital zoom of the image,

d) Two-way audio, etc.
