The EVOLVEO Detective WN8 SMART wireless camera system is eight-channel and operates at 2.4 GHz with its own private protocol. It boasts a camera range of 15 to 25 metres from the main unit in built-up areas. In an open area, this is up to 50 metres, with no obstruction between the main unit antenna and the camera and no electronic interference in the vicinity. The wireless camera system brings the advantage of pre-set and pre-paired cameras with the NVR unit. All your data is stored on the hard drive, so you always have a good view of it. Hard disk up to 8 TB in size can be inserted into the main drive. You can access individual records using the mobile app, which is compatible with both iOS and Android operating systems, and with Windows via the iCMS program. You can also see the footage from the EVOLVEO wireless camera system directly on the monitor. The NVR unit allows connection to a monitor via HDMI or VGA cable.
