The AHD-PIR18 is an HD spy camera hidden in a PIR motion detector housing with invisible infrared night vision. This is a full 1080p HD CCTV camera (AHD, HD-TVI, HD-CVI formats supported) with a built-in audio surveillance microphone. The 940nm IR LEDs are hidden behind the PIR sensor window which makes this camera completely covert even when the IR LEDs are on. 940nm LEDs do not emit a red glow like traditional infrared cameras.
The 3.7mm fixed pinhole lens provides a wide angle of view that is ideal for most applications. It captures a field of view of about 90 degrees. Check out these 1080p surveillance photos captured using the AHD-PIR18. You can also watch this demo video and hear a demo of the built-in audio surveillance mic here.
Important Update! The AHD-PIR18 is now a 4-in-1 selectable format camera. The following video formats are selectable using the OSD joystick that is attached to the camera's video cable.
- 1080p AHD
- 1080p HD-TVI
- 1080p HDCVI
- Analog CCTV (CVBS)
The built-in microphone is optional to use. Simply connect the RCA output of the mic to an audio input on your DVR to capture audio surveillance
. High definition video and audio can be recorded together using an AHD compatible DVR such as the latest iDVR-PRO HD CCTV DVRs. HD iDVR-PROs support traditional analog CCTV cameras as well as the latest 720p and 1080p AHD cameras. When the AHD-PIR18 is connected to an iDVR-PRO, users can also login to view their camera from iPhone and Android mobile devices.
This camera is an excellent choice for indoor
hidden spy camera applications that require full 1080p high definition video. This camera can capture video in normal, low light and zero light conditions. The gimbal wall mount bracket provides installers flexibility to angle this camera in all directions.
Installers can use the same RG-59 or RG6 coaxial cable that is used for analog CCTV cameras to run video from this camera to a DVR. RG59 or RG6 can also be used to run audio.
The 24 IR LEDs can illuminate up to 32 feet and the built-in on-screen display lets installers adjust advanced features such as wide dynamic range (WDR), SENS-UP, shutter speed, and 3D digital noise reduction.
If you would like to
connect this camera directly to an HDMI compliant TV / Monitor, please refer to this BNC to HDMI converter add-on. You can select it from the options drop-down above.
IMPORTANT NOTE: AHD cameras are compatible only with AHD CCTV DVRs.

The 940nm IR LEDs (invisible infrared) of the AHD-PIR18 are hidden behind the PIR window of the motion detector housing. This makes this HD soy camera completely undetectable. The small black circle that you can see below the infrared LEDs is the 3.7mm pinhole camera which naturally looks like part of the motion detector device that this camera is designed to look like. These features make the AHD-PIR18 the best choice for hidden spy surveillance in high definition.
The above video was captured by connecting an AHD-PIR18 to iDVR-PRO surveillance DVR using RG59 Siamese coaxial cable. Please note that this video as created before the AHD-PIR18 was upgraded to a hybrid BNC security camera that supports 4 video modes. At the time this video was made, the AHD-PIR18 only supported 1080p / 2 megapixel video. Please select 1080p video resolution in the lower right of the YouTube video player and watch in full-screen mode to see the best quality video.
Watch the above video to hear a sample of audio surveillance captured using the AHD-PIR18's built-in surveillance microphone.
The above image was captured using the AHD-PIR18. All of the lights are on in the room so that the camera is operating in daytime / color mode.
This image was also captured using the AHD-PIR18 in the same room, however, this was recorded with all of the lights turned off in the room. You can see that the 940nm invisible IR LEDs illuminate this entire room. Although the picture is not quite as clear as a traditional IR camera, this is a trade-off for the covert IR that you get with a 940nm IR camera.
iPhone App View
When the AHD-PIR18 is connected to an iDVR-PRO HD DVR, users can log in from remotely over the Internet to view the camera live. To capture these mobile screenshots, we connected our AHD-PIR18 to an
iDVR-PRO16M DVR. Check out the below images to see this camera being viewed using the iDVR-PRO Viewer app for iPhone.
Above is the remote view in normal light conditions.
This image shows the remote iPhone view with all of the lights off and the camera's invisible infrared night vision mode engaged.
Android Mobile App Viewing
These images were captured while using the
iDVR-PRO Viewer mobile app for Android. The camera is still connected to the iDVR-PRO16M at our office and we are accessing the DVR using WIFI on our demo network. This works the same as viewing the camera from remotely over the Internet.
Here is the infrared view from the Android app.
Cable Diagram
The below image shows the cable leads and connectors that are used to install the AHD-PIR18. You can also see the gimbal bracket mount.
- DC Power Input - this camera includes a 12V DC power supply that connects to this input. The power connector on premade RG59 Siamese cables can also be plugged in or a PT-3 power cable lead if you are using a spool of RG59 Siamese cable.
- Audio Output (RCA) - if you want to capture audio, connect this RCA output to the audio input of your DVR. You can use RG59 coaxial cable if you plan on using the built-in audio mic.
- AHD Video Output (BNC) - this is the AHD video output that you connect to your AHD DVR.
- OSD Joystick - the OSD joystick that is included with this camera allows the installer to fine tune the software settings of the camera. For most installations, the factory default settings work best and this does not need to be adjusted.
Mount & Installation
The AHD-PIR18 is simple to install. The wall mount bracket attaches with two screws and the PIR camera simply slides on to the wall bracket. The installer can then adjust the angle of the camera in any direction because of the gimble mount.

Analog CCTV Spy Camera
This hidden PIR camera is also available in an
analog CCTV version, the PIR-IR60. It comes in the same exact PIR sensor body as the AHD-PIR18 and uses the same invisible IR LEDs. The difference is that is designed for CCTV DVRs (not AHD - analog high definition) and supports 960H resolution (960 x 480), not 720p resolution (1280 x 720).
Please note that this camera is also available in a
720p AHD CCTV model here.
An optional
BNC to HDMI converter can be ordered with this camera. The converter allows you to connect your security camera to a TV via the HDMI input of your TV. In addition to the BNC video input on the converter, there is also a BNC loop output so that you can connect the camera to a security camera DVR in addition to a TV / monitor. The BNC loop output is optional to use.
This device can be used solely as a way to connect your security camera to a TV for a live view only or you can also use the BNC output to also connect the camera's video to a second device, such as a DVR for recording video surveillance footage. You can see this in the above installation diagram.
This camera works great with
Viewtron security camera DVRs. Viewtron 4K CCTV DVRs are hybrid. They support analog CCTV cameras, HD BNC cameras, and network IP cameras up to 4K resolution.
