Methods of connecting an IP camera system
with PoE injector
This solution with PoE injector is used when you require a separate power supply for the camera.
with PoE recorder
Using a PoE recorder is a simple way to connect and power an IP camera system over a single cable at the same time.
with PoE switch
This option is suitable when you place the recorder out of range of the camera cabling. It is also possible to power and merge data from IP cameras, for example, in the attic of the building, and only one patch cable needs to be stretched to the lower floors (for example, due to the small space in the protector) and connected to a common LAN internet network. The recorder can then be connected anywhere on the same LAN.
WIFI network for outdoor IP camera coverage
As mentioned above, IP camera systems offer a huge number of variations in video transmission, including wireless. You can combine wired cameras with wireless ones, or make a wireless link between the wired ones, so it's possible to cover virtually any security requirement for anything.Below are just a fraction of the examples that can be built from an IP system.
Wireless cameras not just for the garage
If you buy a wireless camera to secure remote areas, you can either place and set it up to have sufficient signal to your home WIFI network, and if that's not possible, you can use an outdoor WIFI unit to create your own network to communicate with the cameras.
Example: I've strung cameras around the house using a cable, that wasn't a problem, but I still want to monitor the garage which is 30m from the house. Obviously the home WIFI doesn't catch on there, so I need to connect the current network where the other cameras and the recorder are to the garage somehow. The ideal is to cable an outdoor WIFI unit into the network, which will make a new WIFI network for the cameras with sufficient signal strength and coverage. I will then power the WIFI cameras from the garage. Everything will then be connected on one network.
Wireless link for longer distances
If you have two locations that are up to hundreds of feet apart in line of sight, then obviously digging a link is unrealistic. That's where a wireless link comes in, which can reliably connect these two locations. This link is already configured and essentially replaces a cable, so it's just like stretching a metallic or fiber optic line.
Example: I have two buildings that are 200m apart I need to monitor both with CCTV. The first building has a recording device and several IP cameras. The devices are connected by metallic (cable).
In the second building I will build a virtually identical camera system with a few differences. No active element (router, AP) will be needed and the system will be connected directly to the wireless link unit via PoE switch. In the first building I will connect a wireless link to the router, which will provide the connection of the second building to the first. Once configured, the second building will connect to the first using the same network used by the entire camera system.
