Wireless cameras typically have less features and less resolution which is why we try to emphasize using point-to-point (P2P) wireless radios or access points (APs) to send the camera data to the NVR while using a PoE switch near the cameras to power the wired cameras. A wireless bridge is the Wi-Fi data communication between two wireless access points.
With wireless cameras, you’ll still have to power them, so you might as use the above solution for wireless data while taking advantage of the better features and resolution of wired cameras.
For example, gas stations typically would use a P2P wireless bridge to put cameras on one or more islands, presuming there is a wiring challenge or obstruction to get wired devices connected to the island(s). We can setup a P2P wireless netowrk for a single island or P2MP (point to multi-point) wireless network for multiple islands. You would just need to put the PoE switch for the cameras somewhere, whether underneath the island or inside a weatherproof box on the island out of arm’s reach.
The important thing to consider is clear line of sight (LoS). When it comes to gas stations—especially those in less urban areas—you typically have large tractor-trailers on the property whether pumping gas or filling up your gas tanks. These large trucks can block line of sight. When LoS is blocked, your cameras connected via wireless data will go offline. In some cases, a power cycle may be required to bring them back online. In summary, you need to have clear LoS between the main building and the canopies, even if that means installing the wireless radios from a pole on the roof.
One caveat is with the placement of the wireless radio. It must have 6 ft of space above and below it for the for the Fresnel zone. And there should be no obstructions in front of it. So, if installing it from a pole on the roof, the pole should be at least 7 ft high, and there should not be any ledge on the roof such as a parapet? Alternatively, the wireless radio can be affixed to the side of the building, providing that it will have clear LoS over any potential obstructions.
These wireless APs have a range of several kilometers or miles. While the APs themselves are highly resistant to weather and high winds and storms, the actual weather itself might act as an obstruction for the wireless traffic.
Trees and other non-solid obstructions can be managed using different wireless frequencies. The three most common wireless frequencies are 2.4GHz, 5GHz, and 900MHz. The 2.4GHz frequency has a longer range but is more susceptible to interference. In addition, there are numerous other devices that share that frequency. The 5Ghz frequency has less range and is capable of much higher speeds, but is less susceptible to interference. The 900MHz frequency is rated for lower speeds and shorter distances than 2.4GHz, but it can more easily penetrate through trees. The most common modern-day frequency is 5GHz.
We can pre-configure wireless APs and send them to you for DIY installation so that you can easily create your wireless IP camera network without doing any programming. We can even program the camera system in-house for an additional fee before shipping it to you (or potentially program it remotely at your site) so that it’s completely plug-and-play when you install it.
In addition, we can customize Wi-Fi access points for your staff and/or patrons to be able to connect to the Internet at your property. We can create guest networks so that your guests or patrons cannot access the same network as the staff.
