DPRO-AD940 940nm IR LED CCTV Camera Surveillance Video
The DPRO-AD940 is a 940nm IR LED CCTV camera. This vandal-proof dome camera has 30 invisible infrared LEDs that are used when it is in night surveillance mode. 940nm LEDs do not emit a red glow like traditional infrared surveillance LEDs do.

In this video we demonstrate the day and night video surveillance capability of the DPRO-AD940 dome CCTV camera. This camera uses 940 nanometer IR LEDs when it switches to infrared night mode. This means that the LEDs do not emit a red glow as traditional infrared LEDs do. Let's get started.
In this first segment of video all the lights are on in the office. The camera's obviously in daytime mode in color. I approach the camera from about 21 feet away and then I stop at about 7 or 8 feet away. I'm going to turn off the lights now and it will take just a second for the infrared cut filter to engage and for the infrareds to come on. There it goes. I'll start back at, again, about 20 feet away from the camera and I'll try to stop at about the same point.
This is 940 nanometer LEDs working right here. The room is completely dark. There's no light in the room right now. That's the type of performance you can get from the camera with zero light. I'll turn the lights back on. The IR cut filter will disengage in a second once you see it turn back to color. We're back in daytime color mode now.
The feature of the AD940 that makes this camera unique is use of the 940 nanometer IR LEDs which do not glow. The other main features are that it has a 700TVL Sony image sensor which makes it compatible with all analog CCTV DVRs, including the new 960H video format. The 2.8 to 12 millimeter varifocal lens gives installers a lot of flexibility in adjusting the angle of view and zoom level during installation. Because this camera is IP67-rated, it could be used for indoor or outdoor video surveillance applications, and the dome enclosure is also vandal-proof. This camera is dual voltage so it can use either a 12 volt DC or 24 volt AC power supply. The tri-axis lens mount allows the camera to be ceiling or wall-mounted.
