DI20 IR Illuminator | Long Range Infrared Flood Light for Security Camera (w/Power Adapter)

It's a great light, well made and very bright. It's too bad it doesn't have a high/low switch. I had been using their AI4 model and it wasn't bright enough for my needs and at 20watts this is a bit too bright. Updated: Our NVR has exposure compensation settings. Which, according to the manual ..." Images produced by wide dynamic range (WDR) function sensors can have proper exposure on both the darker and lighter parts of the image, giving more detail across a wider dynamic range between the shadows and highlights by brightening dark areas and darkening bright areas.". Enabling exposure compensation solved the brightness problem.

Used to enhance camera nighttime ability. Works well.

Necesitaba un iluminador infrarrojo para cámaras de seguridad en un area donde las cámaras no contaban con esa función. Una sola luz hizo que la noche se convirtiera en dia en modo infrarrojo. Incluso los videos de seguridad de noche son mas nítidos que los mismos de dia. Coloque la luz en una esquina del area a iluminar y todo un cuarto de 30 metros cuadrados quedo completamente bañado de luz infrarroja, ayudando a las cámaras a ver de noche. La instalación fue muy sencilla, solo perforar para colocar los paquetes y atornillar la luz en la pared.

Electrical design: This illuminator uses a switching, buck converter power supply. This is good because it’s much more efficient than a linear power supply, generates less heat, and accepts a wider range of input voltages. From my testing power consumption is stable from 12 to 24 volts, dropping to half power at 10 volts, and dropping out completely around 9 volts. The DC power connector is a 2.1x5.5mm center positive barrel jack. This is good because it’s a very common connector for 12V DC equipment. The light sensor on the back operates instantly when covered. I didn’t test for hysteresis. Construction: The LED emitters and power supply are all on a single, custom PCB. This is good because it makes for a more compact product and should make thermal bonding to the chassis simpler. The chassis is custom, die cast and power coated aluminum. It looks to me as though it was assembled from the front and the front window was glued in place. No screws are visible and I doubt there’s a nondestructive way to open it. The front window is shiny and appears black due to the IR pass filter. Accessories: The illuminator has a female 1/4”-20 thread tapped on the back. The included ball mount is cast from a non-ferrous metal and powder coated. I like the mount, it’s easy to install, sturdy enough, and ought to hold up to the elements better than plastic. Screws, drywall anchors, a drill template, and a stub of adhesive heat shrink tubing are included Optics: The illuminator is easily visible at 100 feet if you’re looking for it but easily overlooked if you aren’t. On my phone camera it’s about as bright as a 1 watt 2700k LED bulb, to my eye it’s much dimmer. The beam spread is wide and smooth, no hot spots. I personally wish it were tighter in the vertical axis to illuminate less of the foreground and soffet, but maybe it was hard to source LEDs with an asymmetric radiation pattern. Water resistance and longevity: I just got it today, I’ll try to update this review in a year if I remember. Conclusion: Seems great, this is pretty much what I’d do if I were designing an IR illuminator. Good job Tendelux!

As a flood light to light up dark patches that your camera's build in IR can't reach it's OK but not for large or distant areas. The build quality is very good though.
