HD-TVI cameras are very popular nowadays because they provide high resolution images and are cheaper and simpler to install compared to IP cameras. These types of cameras are called HD over coax cameras, technically analog cameras but are able to transmit HD images via (existing) coaxial cables. They belong to the same family with HD-CVI and AHD cameras. You may need to read this article to get more in-depth knowledge regarding this kind of technology: Differences between HD-TVI, HD-CVI and AHD.
Many installers are used to working with traditional analog cameras that utilize RG-59, RG-6 and RG11 coaxial cables and BNC connectors. This type of installation is always faster and simpler compared to the IP systems. For traditional or HD-TVI analog camera installation no learning curve is required because the whole procedure is the same as the old analog CCTV systems, whereas for the IP cameras it is necessary to have basic IT and networks skills for equipment setup. Let’s take a look at the 7 benefits of HD-TVI cameras.
1. High definition images
HD-TVI cameras are able to capture HD resolutions such as 720p, 1080p, 4MP and even 8MP (4K). High definition images provide detail and zoom capability for high-end features like face recognition and vehicle license plates identification even when they are slightly further away from the camera.
2. Easy 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. It’s a “plug and play” type of installation.
3. Low cost
HD-TVI systems offer high resolution at a lower cost. The cost of the cameras and infrastructure are cheaper than IP based CCTV projects. The price range for HD-TVI cameras is $25-$50 and for IP cameras is $100-$150 (average cameras).
4. HD-TVI cameras have no lag
People usually complain 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 a great benefit from this technology. The video coming from a HD-TVI camera is real time and has no lag at all, IP cameras need to do a lot of processing before displaying the video.
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. If you have old analog cameras and you need to upgrade, you can go for HD images by keeping the same cabling infrastructure. This will lower the overall costs.
6. Long distance transmission
HD-TVI cameras allow transmission at distances up to 1600 feet (487 meters) using RG-59 cable (coaxial cable), which is larger than the traditional 100m for the UTP cables (cat5/6) used in the IP cameras network infrastructure.
7. Easy to upgrade
Let’s say you have an existing analog CCTV system and you’re not happy with the picture quality. With HD-TVI cameras you can get HD picture quality and keep the existing cables. All you need to do is replace your old cameras with HD-TVI cameras and replace the old DVR with a new HD-TVI DVR. And of course keep your cable runs. You’ll pay a cheap price and have an HD CCTV system.
8. 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. And nowadays there are tribrid DVRs in the market that allow you to combine analog cameras, HD-TVI cameras and IP cameras. In a way you can get the best of both worlds and lower the cost for your CCTV project.
