The cartridgeÂs inner design is very important and if well designed allows maximum movement control yet minimizes cartridge weight and size.Gitzo uses a special fluid that guarantees a consistent performance over a wide range of temperatures.If you have no internet/wifi, the camera doesn't work. Not the cheapest thing out there, but not the most expensive - kind of mid range. I purchased a logi circle for a condo overseas so I could keep an eye on things in case anyone should break in while I'm not there. I simply connected it to wifi, downloaded the app to my iphone and any time there is any movement, I get instantly notified on my phone and able too view everything (listen as well).
Enhanced Two-Way Talk feature not only lets you hear what’s going on around the camera but also allows you to talk back through your phone, no matter where you are.And with 2-way communication, you can let the babysitter know just in time that, no, Thursday is not frosted cinnamon bun dinner day. Why you need this: I like this camera, very easy to setup and easy to use.I like the optional day review that allows you to see a 10, 30 or 60 second clip of all the activity over the last 24 hours. Works great as long as you have steady wifi services.The infrared also works really well, when viewing on my iphone, it's as though there are lights on inside the condo.I have also used it to keep an eye on my car below the condo at night, it can view well for about 50 feet, recording every movement. We purchased the Logi Circle camera to use as a baby monitor in our nursery.
