Wireless Camera Installation – Easier than you think
Whether it is for monitoring factory work or for UAVs, the wireless option is almost always preferred due to the ease of installation. Till recently, the options of wireless camera streaming consisted of just analog D1 resolution wireless transmitters. You could get them in frequencies of 2.4 GHz and 5.8 GHz. However, there had to be a clear line of sight between the transmitter and receiver. While this worked well for the outdoors, it wasn’t feasible in other areas. Now, the only advantage of these video transmitters are the real time transmission that one can get with them.
Today, the regular customer can easily afford high definition IP cameras due to the price reduction. The price of wireless access points has also fallen and WiFi technology is more dependable. Thus, an IP camera can now be combined with the access point to get a wireless camera.
Why use WiFi Access Points to make wireless cameras?
IP cameras that are WiFi based have a bunch of advantages when compared to analog transmitters. The WiFi signal goes through various obstructions, making it a good alternative and if the transmitter is strong, the signal can go really far. If there is sufficient signal penetration, a video will be clearly transmitted without interference. However, if it were an analog transmitter, lines would start to appear on the video right away.
To avoid interference from WiFi sources if choose a select channel within the access point. Another advantage is that access points that are wireless can connect to devices that are multiple network based. Depending on transmission distance and strength of the inside radio, even 4 IP cameras can be placed on one radio.
The only drawback is that fact that the video will not be in real time. Due to camera type, resolution and signal strength, the video may take a while to reach the receiver.
Setting up a Wireless IP camera system
Setting up a wireless IP camera system is really not that hard. The primary and most important aspect for setting up a system for long range transmissions with a WiFi security camera requires a clear line of sight. The WiFi camera comes with an inbuilt radio and a wireless access point outdoors. This setup works well outdoors. With one AP, about four 1080p HD cameras can be connected and can be integrated into a NVR or viewed on the computer. A 12V power adapter can be used to connect the camera to electricity.
Making a wireless IP camera from a wired one is also possible. All that is needed is a 2.4GHz wireless access point, a security camera and a laptop to view the video transmitted, as long as the devices are not out of range. Once this is done, you can deploy your wireless security camera anywhere; evern near a electricity and a wireless signal shall go back to the NVR, to be recorded and web served.
With just 2 wireless APs, these devices can be configured to each other to work at point to point mode which will provide long range wireless data transmission. Either use a 2.4 GHz or a 5.8 GHz model to connect to one another and create a point to point WiFi connection.
