\"Wildlife<\/figure><\/div>\n\n\n\n

Compact, lightweight, dual-channel weatherproof acoustic recorder.<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

The 4th generation Song Meter SM4 is a compact, weatherproof, dual-channel acoustic recorder capable of long-term acoustic monitoring of birds, frogs, insects, and aquatic life. <\/p>\n\n\n\n

Compact, Weatherproof Design<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Deploy anywhere and keep your data safe.<\/h3>\n\n\n\n

Wildlife Acoustics is the only bioacoustics equipment provider that \ndesigns and molds enclosures from the ground up, rather than modifying \noff-the-shelf housings. The patented SM4 has been designed around the \nfootprint of 4 D-sized batteries and is made of rugged polycarbonate. \nThe result is a very strong, yet lightweight and weatherproof housing. \nThe integrated mounting bracket and weatherproof security cover keep the\n unit safe and dry in the most punishing environments.<\/p>\n\n\n\n

High Quality Recordings<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Maximize detection and fidelity.<\/h3>\n\n\n\n

The SM4 features two second-generation built-in microphones that \ncreate higher quality recordings than previous generations of Song Meter\n microphones. The low-noise microphones have a superior signal-to-noise \nratio so you capture more \nsounds that matter to you.<\/p>\n\n\n\n

Dual-Channel Recording Capability<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Two channels for more recording flexibility.<\/h3>\n\n\n\n

Take advantage of the SM4\u2019s dual-channel feature to ensure that \nrecording continues \u2013 even after one microphone is disabled by \nwildlife-incurred damage. Record in stereo or mono using the built-in \nmicrophones, or connect one or two cabled microphones or hydrophones. \nAdding additional runs of cable to the external microphone gives you the\n ability to capture audio from far-off wildlife such as birds in the \nforest canopy or frogs at a nearby pond.<\/p>\n\n\n\n

Extended Deployment Times<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Capture months of acoustic data.<\/h3>\n\n\n\n

The SM4 features efficient circuitry that allows up to 400 hours of \nrecording time using internal batteries. In Sleep Mode, between \nscheduled recordings, the SM4 uses almost no power, allowing it to \nremain idle for months \u2013 meaning longer deployments, and fewer trips \ninto the field.<\/p>\n\n\n\n

Use the optional power cable to extend deployment times even further with an external battery supply and\/solar panel.<\/p>\n\n\n\n

Easy-To-Use Scheduling<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Choose a schedule or create your own.<\/h3>\n\n\n\n

To get you started quickly, the SM4 features easy-to-use Quick Start \nschedules, such as sunrise to sunset. You can also customize your \nschedules for specific recording needs. The free SM4 Configurator \nsoftware can be used to configure settings and schedules from a \ncomputer. The SM4 Configurator software also provides a Security Lock \noption to prevent accidental changes to deployment and recording \nsettings.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Large Storage Capacity<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Capture terabytes of data.<\/h3>\n\n\n\n

The SM4 has two SD card slots that accept SDHC and SDXC cards. When \nfitted with two 512GB cards, the SM4 can store over a terabyte of data.<\/p>\n\n\n\n

In addition, you can save card space by using W4V Compression. The \nformat doubles the capacity of your SD cards with no noticeable \ndegradation of recording quality. The resulting W4V files can be opened \nwith and\/or converted to uncompressed WAV files using the free version \nof Kaleidoscope software.<\/p>\n\n\n\n

Available GPS Accessory<\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Save money with a single GPS antenna.<\/h3>\n\n\n\n

When deploying multiple recorders, use a single GPS antenna to \nreliably set and synchronize the date, time and location settings for \nmultiple recorders.<\/p>\n\n\n\n

Longest Warranty Available<\/h2>\n\n\n\n

The Song Meter SM4 was designed for use in extreme weather conditions \u2013 from jungles and deserts to parts in between. In fact, we’re so confident that the SM4 can endure the most extreme environmental conditions, we back it with a 3 year warranty. That means you can focus on research, not equipment.<\/p>\n\n\n\n
