They then work by transmitting video through an Ethernet cable to an IP address. The great thing about these is that you can monitor and control them from any computer in any remote location as long as you have Internet access. Along with convenience, using these cameras also drastically reduces costs because you do not need any other hardware. These can be used to protect the outside or inside of your home.
There are IP cameras that are designed for indoor or outdoor use, while others are specifically for indoor use only. If you are more worried about protecting the outside of your home, then you definitely will want to go with one of the outdoor surveillance cameras. This way, you will be able to monitor your home while you are at work or on vacation. All you will need to do so is the IP address and Internet access. You will not have to worry about going away for extended periods of time anymore because you still will be able to check up on your home.
Many people these days are using IP cameras to keep an eye on their children and the babysitter while they are at work. Regardless of how many background checks and references you get for your babysitter, you never can be absolutely sure how they are with your children when you are not there. With these cameras, you will be able to see how they act with your children when they think your eyes are not watching. Because a child's safety is the main concern of parents, these cameras are irreplaceable. These are the only way you can know for sure if you chose the right babysitter.
Because you most likely will not be able to watch the entire video feed at once from your IP cameras because of other priorities, you actually can get e-mails that notify you of motion. You then can log into the IP address and see what is going on. This is helpful for times when there should not be movement going on at your home. It might end up not being anything, but it always is better to know right away than to go home to a house that has been broken into.
