PV-RC400UW Feature Focus:  


LawMate 4K Ultra HD Video Quality 

PV-RC400UW is the first LawMate DVR camera in 4K resolution. This is the resolution of 3840 x 2160 pixels which results in clearer and more detailed images that are capable of displaying more information at once. This standard is widely used in media, television broadcasts, and now in the security industry as an important factor for professionals when collecting video evidence in ongoing investigations. 

Built-in WiFi module in covert keyfob DVR design 

LawMate PV-RC400UW has a built-in Wi-Fi module that allows you to connect your keyfob camera to your smartphone and via the smartphone app you can have full control of your Lawmate keyfob camera. You can change the settings, start and stop recordings, set time and date, and operate other features. Thanks to the Wi-Fi button you can deactivate WiFi options so all recordings are stored on a complimentary SD card in which case the keyfob camera is operated by pressing buttons on the device itself. 

Capturing videos in frame rates up to 120 fps 

Various frame rates provide greater flexibility in post-production and with the advance of technology, the need for higher frame rates grows. The options of capturing videos in 25, 30, 60, and 120 fps give you the flexibility to capture the best video for your particular needs – whether you are an investigative journalist or private detective. 

Large SD Card storage available  

This keyfob camera comes with a lower-capacity SD card for storing data but it is also compatible with larger-capacity SD cards with a maximum of 256 GB. The larger capacity is for some clients crucial when it comes to collecting a large amount of data. This is a new feature that is now available in this latest LawMate kefob camera.
