Field of View Calculator

The Field of View Calculator (FOV) is used to predetermine proper lens selection prior to installation. To do so, enter the camera lens format, the distance to the object, focal length of the lens, and click “Calculate” to see the field of view you can expect with that lens. The Field of View Calculator also works in reverse. If you know the field of view you need, enter it and the distance to the object, along with camera format to find the focal length you will need to get the field of view desired.

We love our livestock system, even when we are not around we can check on everything to make sure all is good. My wife now has peace of mind that while we are away everything is being taken care of. Thank you very much for your great service and advice on our livestock camera system.

Being a CCTV installer for over 15 years we have tried plenty of wireless video products. Your systems are the only one's we will use. The systems are as advertised and your tech support helps us design systems for our customers. Please let me know if you need a reference and we will be happy to speak to anyone about your wireless video equipment.

Fabulous product. Works great right out of the box. If you ever need a testimonial or someone to talk to a potential customer please let me know. The university is so impressed, they have already committed to a duplicate system for the infinity pool they just broke ground on yesterday. It will be located on the other side of the same building. I will let you know when we need that system. Thanks again for your great service.

Your WVC-SD COFDM wireless video downlink is EXCELLENT! This is the first video link we have used that proves a solid flicker-free signal As a professional aerial photographer we have used Analog Wireless Video Systems for years. The results were always the same, excessive video breakup and distortion. After spending hundreds if not thousands on cheaper systems, we finally bit the bullet and purchased the COFDM Digital downlink. We couldn't be happier with the results. We are looking forward to the release of the HD system when it becomes available

The 6 Weatherproof 1000ft. Range Wireless Video Links and 150ft. Nigh Vision Cameras were exactly as advertised, Plug & Play. Even at temperatures that reached -49C the equipment has been working great. We will definitely be calling you again when we need more surveillance cameras.
