With cameras that communicate with wifi NVR’s placement of the camera close to the NVR is definitely something to be taken into consideration. The speed test can be performed on a cell phone or laptop and will identify where the signal will be strongest.Cameras with built in wifi that talk to an existing network must be within 300 feet for optimal performance. A quick speed test will help you determine if wireless cameras are not an option. Whether its trees, poles or concrete walls, objects blocking the signal strength is definitely something you want to be aware of and keep in mind if you are purchasing a wireless system. Video fragmentation occurs when there is some kind of disruption in the signal. This is a good option for homes and business that require a super secure system with no network vulnerability. While analog wireless cameras usually have a lower resolution compared to IP, there are some that are available with a higher resolution. This is not a good option for homes or business’ in the country where cell phone service is limited. Also keep in mind there would be a monthly fee for using a 4G network similar to internet, if you don't pay the bill the cameras would have no signal. One of the things to consider with this option is not only is a sim card needed but also a cellular modem and a switch would need to be encased in an enclosure if the camera is placed outside, this is assuming there is a nearby power supply if not a solar panel would be needed. The modem connects to the internet just like a cell phone. These radios can be placed every 200-300 feet to create a bridge that carries the data back to the recorder.ĤG Wireless works similar to a cell phone. Wireless Bridge is essentially just more than one wireless radio that communicates the data to each other in long range placement. The recorder has 2 jobs- recording the captured video and being a standalone wifi network. This option is quite popular because no established wifi is needed. Range is usually around 300 feet barring the absence of physical obstructions like trees and poles.Ĭameras with built in wifi communicates with recorder that also has built in wifi. This option needs either a recorder or an SD card to store video. Long range placement may require additional equipment such as wireless radio. One of the things to keep in mind with this option is the distance from the camera to the wifi connection. Cameras with built in wifi that communicate with existing network requires an established wifi connection.
