Why is DTV surveillance a better solution?

Advantages of DTV surveillance

A seamless full HD upgrade solution for CCTV systems

Same structure as current CCTV system

Existing coaxial cables reusable

Requirements for cable quality is minimal (3C-2V, RG-59)

No need for network expertise

The structure of DTV surveillance is simple and straightforward because its deployment methods are exactly the same as analog CCTV systems. When upgrading a CCTV system to a DTV system, pre-existing coaxial cables, such as 3C-2V or RG-59 types, in the current CCTV system can mostly be preserved and reused in the new DTV system. That means the requirement for cable quality level is minimal in a DTV surveillance system. To migrate to HD quality videos, one only needs to replace the original CCTV system with DTV devices at the camera end and at the storage end. There is no need to re-deploy the coaxial cables or re-plan the whole structure. Pacidal's DTV surveillance is definitely a seamless solution to upgrade a current CCTV system to a full HD one, which efficiently saves installation time, material and labor costs.

For new installations, 5C-2V or RG-6 coaxial cables are recommended, which are the most common types of coaxes in the market now.

Unlike IP surveillance, the installation of DTV surveillance does not require any complicated TCP/IP setting procedures. It is straightforward for technicians or even end users without network expertise to install and to deploy DTV cameras effortlessly.

One coaxial cable to connect multiple channels of videos (optional)

16 channels of full HD videos over one coax cable

Cable and labor costs saving

One of the most remarkable features of Pacidal DTV surveillance is it runs multiple video channels over one single coaxial cable. That means on installation sides, what you need is only a single coaxial cable to carry multiple videos sources from different cameras, which alleviates the problems of being overwhelmed by a jumble of coaxial cables that occurs in other solutions. This “daisy-chainable” capacity, a unique feature for DTV surveillance, not only increases flexibilities on system structure planning, but also makes the deployment process easier and more efficient.

More flexibility on deployment

Star topology


DTV surveillance supports multiple types of deployment methods, including star topology and daisy-chain. It enables much more flexible ways to deploy security cameras. That’s one of the reasons why the DTV surveillance outperforms current CCTV solutions or any other HD solutions, such as HD-SDI, HDCVI, HDTVI, or IP surveillances, which only supports star topology. For daisy-chain, DTV surveillance’s capacity is up to 16 cameras by using only one coaxial cable.

The ultimate long-distance full HD solution

1000+ meters without repeaters (5C-2V, or RG-6)

500+ meters without repeaters (3C-2V, or RG-59)

Suitable for perimeter surveillance applications

The breakthrough of DTV security technology in the surveillance industry is that it supports supreme long-distance video and audio transmission up to 1000 meters, without the aid of any repeaters. The range of transmission for DTV surveillance is much longer than any other types of security solutions, such as IP cameras, or CCTV cameras, HD-SDI cameras, or HD-CVI cameras. This 1000-meter transmission distance can be achieved by using a single 5C-FB or a RG-6/U coax cable (, through which multiple full HD channels are simultaneously transmitted). With cables of lower quality level, such as 3C-2V or RG-59, the transmission range can reach 500-meter distance without repeaters, which still outperforms all the other existing HD solutions. Furthermore, thanks to the nature of digital transmission, DTV surveillance’s signal quality won’t degrade after travelling through long distance. Pacidal DTV surveillance can fulfil the needs for applications requiring perimeter surveillance or long-distance transmission, especially suitable for transportation, construction sites, campus, military base, hotel, parking lots, road surveillance, critical infrastructure, residential community, and so forth.
