There are two very easy ways to use your PC for recording video from your hidden and IP cameras.
The first way is to use an USB DVR. These devices are generally inexpensive, small and are simply connected to an open USB port on your PC. They usually allow up to 4 cameras to be connected to them at one time.
Most USB DVR’s come with software that you install on your PC to allow it to record video and for you to be able to view that video live and recorded, across the internet from any PC in the world.
One limitation to the USB DVR is that most only allow 4 cameras maximum to be installed at any time and if your needs require more, this may not be the right option for you.
The second way to use your PC to record video is by using an IP camera. They are extremely versatile devices that can connect to either your DVR, PC or right into your existing network using an Ethernet/CAT5 cable.
Most IP cameras come with software that you install on your PC or DVR to allow you to view the recorded video as well as to adjust any available features the camera may have.
If you also have your home network connected to the internet. You can generally use the software for the IP camera to create a secure webpage that can been seen only by you across the internet.
This means that you can access either real-time or recorded video from the IP camera across the internet from any PC in the world. This is very useful if you are away from and want to keep an eye on, things at home.
IP cameras generally will allow up to 16 cameras to be installed at one time and are generally a better fit for those with larger needs.
So depending on how many camera you would like installed, either of these two options will allow you to use your PC record the video coming from your hidden or not, camera.
