Security Alarms

Can security alarms and fire alarms be set off with high pitch sounds.?

I know home alarms can be set off with sound because of glass break, but can fire alarms be set of with different pitches of sound

I have never heard of a fire alarm being set off by sound. They are designed to detect smoke.

Sony Rapid Dome PTZ Network Security Camera $2899.99 The Sony SNCRX530NB incorporates an 18x auto focus zoom lens that allows users to view distant object with details. A 12x digital zoom is also available to achieve a maximum zoom of 216 times.This camera incorporates advanced compression technologies to transmit image data in three different formats: JPEG,MPEG-4, and H.264. Users can choose any of these compression formats to match their system’s network environment and application requirements. What’s more, this third-generation camera can simultaneously stream JPEG and MPEG-4 data for even greater operational flexibility.The camera employs robust detection methods – Intelligent Motion Detection (IMD) and Intelligent Object Detection (IOD) to maximize the efficiency of the monitoring system. Object ‘tags’ (or IDs) and associated position data are created within the camera. This data – also called metadata – can be streamed independently or along with video over a network to work in conjunction with rules or filters (such as virtual borderlines) defined in application software to perform actions such as initiating alarms or beginning to record. This rules-based processing can minimize server workload, network bandwidth,and storage requirements.In addition, a number of other convenient features have been incorporated into this camera to meet your needs such as, a Day/Night function, Voice Alert, Privacy Zone Masking, and wireless capability. With its built-in intelligence and rich features, this Sony multi-codec camera is ideal for a wide variety of surveillance and monitoring applications.This dome camera has a high-speed 360° endless panning (or rotation) capability, which allows users to precisely capture almost any object surrounding the camera. In addition, by employing a ¼" Exwave HADTM CCD, the camera delivers exceptional picture quality for any remote monitoring application, even in low-light conditions.

DIGIOP Black Network IP Indoor Mini Dome Security Camera $399.99 This digital day/night indoor mini dome security camera has superior image quality using a 1/3" Omnivision CMOS sensor. The DIGIOP BLK-IPD103 delivers up to 30 FPS high resolution video @ full D1, 720 x 480. It features H.264 compression technology for optimized image quality, and lower bandwidth and storage requirements.Digital Day/Night – Digital day/night (also referred to as electronic day/night) improves low light sensitivity, delivers a sharper image in low light conditions, and enables the camera to see in the dark without the help of external IR illuminators. Unlike true day/night cameras, which use a mechanical filter, the camera electronically adjusts colors during the day instead of using an infrared filter. This allows the digital day/night cameras to deliver similar benefits of true day/night cameras, but at a lower cost. Without the need for a physical filter, digital day/night technology can be leveraged for smaller form factors, such as bullet cameras.Digital Slow Shutter — Digital Slow Shutter (DSS) allows you to see clear images in extreme low light conditions without the need for artificial illumination. DSS technology (also known as 'sens-up' or 'sense-up') enables very low light capabilities by slowing down shutter speed to allow more light to be collected by the CCD imager. This means that the camera can capture color images in conditions of near darkness. The user can adjust these settings to specify conditions that engage this feature automatically.Motion Detection – The Motion Detection feature allows you to integrate your cameras with external devices – to engage that device upon the detection of motion. Common devices include security lights, alarms, access control devices, and more.

Combined with the 2-way audio support, you have a powerful solution for secured entryways or corrections facilities.3D Noise Reduction (3D-DNR) is an enhancement of traditional DNR technology. 3D DNR incorporates frame-to-frame noise reduction with spatial noise reduction. Spatial noise reduction compares a pixel with its neighboring pixels to detect and remove unwanted noise found within the frame. It processes the entire image to remove digital artifacts and graininess to enhance image clarity and sharpness.The PoE (Power over Ethernet) feature allows you to run power to your camera through your Ethernet cable, saving you time and money during installation.

3S 2.0 Megapixel Day/Night Box Security Camera $299.99 This 3S 2.0 Megapixel IP box camera combines high-quality video with advanced image processing features. 2.0 Megapixel resolution provides highly detailed images at a size of up to 1600 x 1200 pixels, which is equivalent to HDTV image quality.

During the day the camera uses a physical IR filter to filter out IR light that can cause color shifts. The IR filter is removed during nighttime mode to allow the camera to see in the dark. 3D digital noise reduction (3D-DNR) is an enhancement of traditional DNR technology that incorporates spatial noise reduction along with frame-to-frame noise reduction. Spatial noise reduction compares a pixel with its neighboring pixels to detect and remove unwanted noise found within the frame. It processes the entire image to remove digital artifacts and graininess to enhance image clarity and sharpness.PoE (Power over Ethernet) support allows you to run power to your camera through your Ethernet cable, saving you time and money during installation.The camera comes with mounting hardware, quickstart guide, application disk with full manual and software, 2-year warranty and 30-day money-back guarantee.
