Stream live video from CMOS-lens style devices over the internet via this hand-held Wi-Fi DVR. This device records in 720 x 480 resolution from LawMate analog cameras. You can connect the DVR to your smart device via the LawMate app to review and control your video stream remotely. You can also transfer your data using either USB 2.0 connectivity or microSD memory up to 32GB.

WiFi Connectivity operates via 802.11b/g/n Wi-Fi band. It can remain stationary or mobile and transmit while still within signal range.

The unit’s size is perfect for office, business, home, and even your coat pocket. It is an excellent complementing unit for most small CMOS lens units from Lawmate.

The most off-guard footage is taken when no guard was expected.

Hidden cameras and hidden microphone devices have a very unique advantage; capturing imagery of natural activity within the environment they are placed. These items can help protect protect your family and office. Through technological observation, you can keep exact record of suspicious behaviors and perhaps even prevent a serious crime before it’s too late. The way these devices are disguised allows them to blend into the environment of yards, households, businesses, and desk tops.

  • All the associated applications/apps for our WiFi devices are free to download. Our WiFi hidden recorders will allow the performance of on-the-spot home and office checks.
  • Using built in SD card functionality/DVR data transfer, you can extract any recorded footage for law enforcement or attorneys, to ensure justice.
  • With the overwrite function, current information takes priority over old unimportant data in order to prevent running out of data space.
