HD-TVI cameras are very popular due to the fact they are still analog but they have high resolution just like some of the basic IP cameras.
The camera are also cheaper and easy to install compared to the IP models
For many years CCTV installer are working with traditional analog cameras with RG-59, RG-6 and RG11 coaxial cables and BNC connectors. That type of installation was always fast and simple and people prefer to keep that way.
After cameras installation, it is necessary to configure the DVR for recording, a simple and ordinary task that a good technician is able to perform quickly without the need for advanced skills.
When the same technician needs to install a HD-TVI camera, for example, the procedure is exactly the same. He/she just need to attach the camera into its place, run the coaxial cables, crimp the BNC connectors at both ends of the coaxial cables and configure the DVR for recording.
For traditional or HD-TVI analog camera installation no learning curve is required because the whole procedure is the same, whereas for IP cameras it is necessary to have basic IT and networks skills for camera setup.
Now that we have discussed the basic issues related to the installation let's take a look at the 7 benefits of HD-TVI cameras.
1. High definition images
High definition images (HD) provides detail and zoom capability for things like face recognition and vehicle license plates identification even when they are slightly further away from the camera.
2. Simple to install
There is no need for extra network skills. Installing HD-TVI cameras is as easy as installing traditional analog CCTV cameras and does not require a complex network infrastructure, so the installation is much faster when compared to the installation of IP systems.
3. Low cost
HD-TVI systems offer high resolution at a lower cost. The cost of the cameras and infrastructure are cheaper than IP bases CCTV projects.
4. HD-TVI cameras have no lag
People usually complay a little bit about the lag (or delay) on IP cameras. With traditional CCTV cameras there's no such thing and the same is true for HD-TVI cameras, so that's is a great benefit from this technology.
5. Use the existing Infrastructure
HD-TVI enables fast and high quality transmission using the existing infrastructure with coaxial or UTPs (cat5/6) cables. This reduces the cost.
6. Long distance transmission
HD-TVI cameras allows transmission at distances up to 1600 feet (487 meters) using RG-59 cable, which is larger than the traditional 100m for the UTP cables (cat5/6) used in the IP cameras. network infrastructure.
7. Easy integration
A HD-TVI CCTV system can be compatible with traditional cameras and existing coaxial cables, so in a new installation it is possible to use a hybrid DVR that works both cameras at the same time.
These are some of the advantages of a system based on HD-TVI, it is important to take into consideration that it is very worthwhile to migrate from a typical traditional analog system to HD-TVI technology.
