The HCPRO-420SC hidden fire sprinkler security camera is perfect for covert CCTV / "HD over coax" video surveillance applications. This 4-in-1 HD hidden sprinkler camera supports 800 TV lines of resolution (960H) in Analog CCTV mode and 1080p HD resolution in AHD, HDCVI, and HD-TVI modes. The video modes are switchable using the small joystick that is attached to the video cable.

The 420SC also has a built-in audio surveillance microphone. The audio mic can be connected to an RCA or BNC audio input on a DVR.

A powerful OSD (on-screen display) allows the installer to adjust the settings of the camera to meet the needs of your specific installation. The 3.7mm pinhole lens is virtually undetectable and provides a 90-degree field of view. The HCPRO-420SC works great in low light down to .01 LUX (minimal ambient lighting).

Please check out these sample pictures and watch these surveillance video recordings to see what this camera is capable of (These samples currently represent the Analog CCTV mode of the HCPRO-420SC). When light level goes below a certain level, the camera's picture turns black and white. When lighting increases to a certain level, the camera turns back to day color mode.

This camera is typically connected to a CCTV DVR to record video surveillance. However, if you would like to connect this security camera to a TV instead of recording, please refer to this BNC to HDMI converter add-on. You can select it from the options drop-down above.

Important Note: Click the gear icon in the lower right of the video player and select 1080p resolution so that you can view the video in high definition.

Fire Sprinkler Camera Surveillance Pictures

The following surveillance snapshots were captured using an HCPRO-420SC connected to an iDVR-PRO HD CCTV DVR. This is the 420SC that we have installed in a ceiling tile at CCTV Camera Pros office.

Ceiling Tile Installation - Fire Sprinkler Camera

The camera monitors the main room where our surveillance techs work. This first picture was taken with all of the lights on in the room.

Hidden Pinhole Fire Sprinkler Surveillance Camera

This second picture was taken with the lights off in the room to show the low light performance of the camera. The HCPRO-420SC does a good job in fairly low light. If you need a hidden camera that sees in ultra-low light or no light, we recommend this hidden PIR camera with invisible infrared night vision.

1080p HD Fire Sprinkler Security Camera

This last picture was taken to show users what the OSD (on-screen display) menu looks like. The OSD allows users to fine-tune the settings of the camera specific to their installation environment. The OSD menu is activated and controlled using the small joystick that is attached to the camera cable.

BNC to HDMI Converter

BNC to HDMI Converter

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.

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.
