HD-TVI Cameras

HD-TVI Cameras

HD-TVI security cameras are the models we recommend most at OsmiumTech.  They are easy to install because they can transit HD video over standard RG59 coax cable, or any standard analog CCTV cable. Typically cheaper than IP cameras, they offer zero latency and are easy to upgrade because you can keep your existing CCTV cable.

The cameras are the key elements of every security system, being the “eyes” of the users of surveillance networks. While most of the HD-TVI cameras feature similar technical characteristics that correspond to the HD-TVI standard itself like the 1080p of resolution, there are some features that are unique to each model and offered with the aim to cover special user needs. These are:


Camera type

Depending on the area that needs covering, as well as the camera positioning capabilities, users should select either a bullet camera or a dome camera. The bullet ones are generally better for outdoors, while dome cameras are best suited for use inside buildings. Both are quite easy to install and adjust, but the bullet type is slightly more straight forward. 


Chip and lens

If you are trying to cover a wide area by using only one camera you should try a “fisheye” type of lens that are made to offer a wider field of view for the user. The CMOS which “translates” light into color pixels is also important and must be of a minimum of 2 MegaPixels. Finally, if the camera will be installed in a poorly lighted area, the lens diameter should be large enough to capture as much light as possible. Moreover, CCD chips are known to perform better than CMOS chips in low-light conditions, but CMOS produce a higher image quality in general. 


Vandal proofing

Surveillance isn't always accepted by everyone out there. For this reason, cameras must be adequately protected against hits and other malicious actions. Some come in metal protection casings, while others like the dome-type cameras can be installed in places that are particularly hard to reach.


Night Vision

Night vision is another important camera feature that allows the system to remain operational during nighttime without the need for lighting. The cameras achieve this by using infrared lighting LEDs, but not all night vision implementations are made equal. Check the night vision specifications and especially the maximum viewing distance. 


Waterproofing

For cameras that are destined to be installed outside, the ability to withstand the atmospheric air moisture, low/high temperatures, humidity, and even pouring rain is important. The are waterproofing ratings (IP65, IP66, IP67, etc) that the buyer needs to check carefully to ensure that a camera model is suitable for the intended use. The first digit next to the “IP” part indicates protection against solids with 6 being particles as small as dust, while the second digit corresponds to the protection capabilities against liquids. 1 is dripping water, 3 is spraying water, 4 is splashing water, and 5 is water jets. Depending on what is expected in the installation position, you should choose wisely based on the IP code. 


Remote Control

Finally, and since HD-TVI supports the sending of data to the camera from a control center, the ability of the camera to tilt, zoom, or turn is important. Such operational abilities will allow for the user to get a better view of something, or simply monitor a large area with just one camera. If the camera supports zooming, make sure to check the image sensor size and estimate the image quality drop at the desired zoom level.
