D057-AHD – 840nm IR – 2.5mm Lens – Stortech

This Stortech D057-AHD dome camera is a polycarbonate micro dome camera, 960P AHD which can come with either a 2.5mm or 3.6mm lens, colour/black and white, mirror image cut loop and IP67 weatherproofing. 

With flush mounting and IP67 weatherproofing this camera can be dropped into a body of water up to a meter deep for half an hour. This makes the D057 both an indoor and outdoor camera.

This dome camera is extremely compact but very powerful. With the dome only weighing 115g and having the circumference size of a standard tea mug it is a great covert vehicle camera. 

The main difference between this D057-AHD camera and the D056-AHD-PC camera is that this D057 has an IR sensor. This allows the camera to operate in pitch black using night vision to capture recordings.

• All D057 models come with built-in IR LEDs which make them perfect for low light environments.

Sensor

This D057-AHD model comes with a CMOS sensor which allows each pixel to be read individually. With CMOS sensors using several transistors next to each pixel this allows for lower light sensitivity and will also consume very little power.

This model uses 850nm (nanometers) IR wavelengths which are around 30-40% more effective at distance than the 940nm D057-650-COV-S. The 850nm model will illuminate a greater distance however it will produce a faint red glow when looking directly at a camera or source. The 940nm (also known as Covert IR) is completely invisible and can be used in situations that are required to be more covert.
