A lot of people have the preconceived notion that wireless camera systems have an easier installation process when compared to their wired counterparts. You might think that because we have shifted to wireless from wired in a lot of other technologies; doing the same for security cameras might be a good idea. However, that is not true at all. In a lot of cases, setting up a wireless camera system is a lot more complicated than using CAT-5 cable or coax cable. On top of that, the power source has to be considered as well. So, the cameras would never be truly wireless.
Indoor Wireless Camera Systems
Wireless IP cameras are a must when indoor surveillance is considered. These cameras can have 2.4 GHz or 5GHz wireless frequencies. There are pros and cons to both setups. The 2.4 GHz set up is better because it is more capable of traveling through walls when compared to 5Ghz. On the other hand, a lot of 2.4 GHz routers or access points usually have a dual-band. The issue with that is that if there are a lot of o
- CAT-5 cable connecting the access point to the router
- An NVR connected to the router that uses a CAT-5 cable.
- 4 IP cameras that are connected to wireless access points over Wi-Fi.
- Cameras can be accessed through mobile or desktop apps.
- A single device/router combination could be used to build the system.
Indoor/Outdoor Wireless Camera Systems
- 2 wireless access points
- 2 IP cameras that have to be connected over Wi-Fi to the access point
- Outdoor IP cameras should be in bridge mode while it is connected to the access point while using CAT-5 cable. The cable usually connects the inside of the building to the outside
- Using a CAT-5 cable an NVR is connected to the router
- Video from the IP cameras is recorded by the NVR
- The NVR systems can be remotely accessed
Outdoor Wireless Systems
When it comes to outdoor camera systems, it is necessary to transmit video signals from the cameras over different buildings via Wi-Fi.
- A CAT-5 cable is used to connect the cameras to a network router
- A transmitting outdoor antenna is connected to the router
- The wireless antenna will transmit data with an antenna mounted on a different building
- This antenna on the building is wired to a networked router by using a CAT-5 cable.
Multiple IP Camera Transmission Over WiFi
The same as the one above except there are multiple IP cameras transmitted over the wireless bridge.
- On the left building, the IP cameras are hard-wired to a network router using a CAT-5 cable. The wireless router and wireless cameras are also used.
- The router is connected to a transmitting outdoor wireless antenna.
- The wireless antenna will communicate with the antenna that is mounted on the building on the right.
- The one on the right is wired to a network router with CAT-5 cable.
Wireless security camera systems are not as useful or as easy to use as one might think. The set up is more difficult than a wired system. But you might say that it is worth the time and energy spent on setting it up right? The answer is not quite. The reason being, it is important to keep in mind that cameras like this are not as reliable as wired systems.
