A varifocal security camera offers security installers and integrators a few advantages over a fixed lens security camera including flexibility.
A common complaint security installers and integrators voice about installing a fixed lens camera is the headache of having to physically re-install the camera in order to change or adjust the field of view.
Going back to the job site to redo the installation causes frustration for both the customer and the installer, and re-installing a camera costs valuable time and money.
Easy Adjustment of Camera Focal Length
Full Frame Illumination is an Advanced Infrared Technology. This cutting edge, light emitting illumination technology offers better low light and nighttime surveillance capabilities than standard IR technology, and numerous other benefits.
The 7 main benefits that Full Frame Illumination are:
Produces clearer, brighter images in low light and at night
Delivers a wider illumination spread
Unique rectangular IR LED design produces a uniformly illuminated image across the entire screen
Reduces overexposure at the center of the image and eliminates hot spots
Eliminates blooming from lights by reducing ambient light pollution
Reduces video noise for a clearer nighttime image, along with reducing bandwidth consumption and video storage requirements
Delivers 30% greater energy efficiency
Produces Clearer Images
Full Frame Illumination technology offers better low light performance than standard IR illumination technology. FFI produces a larger illumination spread, resulting in a crisper, clearer image across the entire scene.
Illuminates a Wider Area
Alibi cameras with Full Frame Illumination technology disperse IR light more effectively, resulting in a wider illumination spread, to cover a larger area while producing a properly illuminated image.
Produces a Uniform Image
Cameras with Full Frame Illumination technology use rectangular IR LEDs to produce IR light in the shape of a rectangle, which fits a screen’s typical size with a 4:3 or 16:9 aspect ratio. The rectangular IR LEDs produce a uniformly illuminated image across the entire screen and is ideal for widescreen HD security cameras.
Eliminates Hot Spots
FFI technology reduces overexposure at the center of the image to balance the contrast within a scene and eliminate hot spots. FFI produces crisp, evenly illuminated video, without a bright circle of light (hot spot) at the center of the image, or dark corners at the edges.
Reduces Light Pollution and Blooming
Full Frame Illumination reduces ambient light pollution from the environment, such as from a street lamp, nearby neighbor’s floodlight, or bright full moon. The reduction of light pollution reduces camera blooming (also referred to as the halo effect), which is the saturation of pixels due to very bright light in the area under surveillance.
Eliminates Video Noise
Video noise (interference in the video signal) is common in low light environments. It shows up as grainy specks in the image and can greatly affect video clarity. FFI reduces video noise to deliver clearer images in low light environments. Eliminating video noise also reduces the load on the network, saving bandwidth and reducing video storage requirements.
Delivers Greater Energy Efficiency
Full Frame Illumination improves illumination efficiency, resulting in a longer product lifespan, and greater energy savings. In fact, FFI delivers 30% greater energy efficiency than standard IR LEDs.
