There are a few things to consider when deciding where to place your Vava monitor. The first is the range of the device. The Vava has a range of up to 30 feet, so you'll want to make sure it's placed within that distance of whatever you're trying to monitor. Additionally, the Vava requires a clear line of sight in order to function properly, so keep that in mind when choosing a location.
Once you've considered those factors, it's simply a matter of finding a spot where the camera can get a good view of whatever area you're trying to monitor. If you're using it for home security, placing it near a door or window is usually ideal. If you're using it as a baby monitor, putting it in your child's room is probably the best option. And if you're using it for general surveillance, somewhere high up with a good vantage point is usually best.
Ultimately, there's no one perfect answer for where to place your Vava monitor. It really depends on your specific needs and situation. But as long as you keep the above factors in mind, you should be able to find a spot that works well for you.
