Varifocal Security Cameras
Vari-focal security cameras are cameras that can be adjusted to adapt to new demands of a CCTV surveillance system. In fact,
these are the most popular bought and demanded cameras. Many people that buy CCTV security cameras are unsure of what
distance or field of view they need. Vari-focal cameras are great because they can adapt to new situations or give end-users a little
play or marginal error when initially developing their CCTV setup. We have dome and bullet cameras with vari-focal lenses.
Varifocal Security Cameras Come In Different Ranges Choose The Right One!
When you are looking for a security camera, look for a camera that has the right lens for what you are trying to see. In fact, you must get the dimensions of the view you need, before you can know what exact lens you need. The field-of-view to distance issue will be a very big part of selecting the right lens. Also depending on your environment, you also need to make sure you purchase the right lens. However, if you are just unsure then you need to take a look at a varifocal lens. Most varifocal lens are in massive variety, but the most common is a 4mm to 9mm lens. In between the 4mm and 9mm setting is a 5mm, 6mm, 7mm, and 8mm lens setting. You can find some 2.5mm to 8mm settings too. Bullet cameras can range from 8mm to 22mm. Dome security cameras range from 4mm to 9mm and 2.5mm to 8mm lens settings. Higher resolution dome security cameras will have a 2.5mm to 12mm setting. Either way you go, you need to make sure that you have the right range. The best way to figure out what camera will work for you is to measure the dimensions of your enviorment. Then determine what the goal of each zone of security is and then select the right fixed lens camera. Depending on how intense your CCTV application is, never rule out a varifocal lens, you might need one to adapt to new situations that arise.
Dome Varifocal Cameras vs. Bullet Varifocal Cameras
Here is a great topic! If you are tying to decide which camera is best suited for your application, then you need to read this analysis carefully. In the CCTV industry no camera can really out do one another when it comes to "real-world" testing. Certain camera can just outperform another no matter what. But it get's tricky especially when the CCTV application is very demanding or unique. The battle between a dome varifocal cameras and a bullet varifocal camera is a tough one, but the bullet camera wins. Overall bullet cameras have a larger variety in lens selections to match pretty much any environment. They can go small range, medium range, and long distance. Where as dome cameras can only go small and medium range. However, dome cameras are to be used in smaller CCTV applications. You also will find dome cameras in more business environments. Residential homes should use dome cameras. They are great in their look and small to medium range in seeing distance. They are also great because they are small in size. Bullet cameras usually do better in small retail, small, medium, and hi-commercial applications. They have some smaller model bullet cameras, but it's design makes it hard to implement hi-technology such as infrared lights, a wide varifocal lens, and microphone a microphone and the camera remain small. It is just no possible, so the shier size of the camera rules out the friendly look most residential homes need. Dome cameras are by no means the best camera overall they win in their own categories, but the bullet camera has a multi-varifocal potential and wins in the category of a camera that can adapt to any environment.
