I have two IR spotlights because the front of my property is absolutely pitch black on some moonless nights and the 4K IP cameras own internal IR lights aren't that bright to see in the distance. Installing these two IR spotlights has made a big difference. Now I can see up to 50 metres (80 feet) away. I can spot cats, foxes and possums in the darkness of the Park across the street and in my backyard by the glow of their eyes. These are about $85 to $99 each. A bit of a rip-off but otherwise are quite long lasting. They automatically turn off during the day. Recommended.
