WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. When you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the unit installation environment and research which functions you want to attain.
WiFi or PoE, which is a good? As a senior technician that has four years in video security industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through cellular transmission (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, after the IP camera supports WiFi, the camera can connect your router without needing hardwired connection. Wireless can enable IP camera become portable, this is the advantage of WiFi.
But there are two downsides on WiFi, which can be; every electronic devices require power supply, which means your IP camera still requires wire for connection.
Up to now, I haven't found any IP surveillance cameras are able to operate with power packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electricity rate of Wi-fi device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters indoors.
When Wi-fi devices will work outdoor without barrier, the transmission distance will be much way.
To increase the WiFi coverage or distance, you can mount WiFi access point. Such an gain access to point (or hotspot) has a variety of about 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable tv (Pet cat5/6) is the key feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP video cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum vitality rate is to 15.4 W of DC electricity (minimum 44V DC and 350mA) to each device.
To be able to provide power for high electric power intake devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Negatives AND PROS OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired wire, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, Ability sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network transition, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than WiFi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to control, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of monitoring market, I came across that WiFi IP cameras are widely used for non-professional indoor security, and PoE IP surveillance cameras are installed for outdoor surveillance system. But if you choose WiFi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which type of cellular IP camera suites and would meet their needs. As a result, they get sucked into buying wireless IP surveillance cameras that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or excellent); what accuracy of data do you want to get? (HD images with or without music) and most importantly, what's your budget?
Second, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Certainly, this feature will rely upon the environment where you want to use the camera.
A wide pan and tilt range is never a bad thing.
Thirdly, zooming capability of the cordless IP camera is also vital.
Make sure that you check the type of zooming potential, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, in particular when you are buying from your local electronic store.
Always request for a test installation as this will allow you to look for the picture quality of the camera.
In addition, it will offer you an possibility to learn how to set up the gear in a proper manner to ensure that you have the best image and music quality.
