WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wi-fi and PoE at same time. Once you connect the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and check out which functions you want to achieve.
Wi-fi or PoE, which is the better? As a older technician that has four years in training video surveillance industry, my response to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through wireless signal (2.4GHz UHF group, 5GHz SHF strap).
Obviously, after the IP camera facilitates Wi-fi, the camera can connect your router without using hardwired connection. Wireless can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, that are; every gadgets require power, which means your IP camera still requires cable connection for connection.
So far, I haven't found any IP cameras are able to operate with electric batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've many things to consider including electricity rate of Wireless device, environment (indoors or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters interior.
When Wireless devices are working outdoor without barrier, the transmitting distance will be much far.
To extend the WiFi coverage or distance, you can mount WiFi gain access to point. This access point (or hotspot) has a variety around 20 meters (66 ft) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over one Ethernet cable connection (Feline5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP camcorders support plug-and-play installation, which greatly reduced the assembly procedures, and get rid of the necessity of ability cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC ability (minimal 44V DC and 350mA) to each device.
To be able to provide power supply for high electric power utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. CONS AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable, no need extra power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable connection, there is absolutely no signal disturbance, no sign jamming.
For properly working of PoE devices, Ability sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive when compared to a traditional network switch, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I came across that WiFi IP video cameras are widely used for non-professional inside security, and PoE IP cameras are installed for outdoor monitoring system. But if you select WiFi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your preferences?
Firstly, establish what you need. Many purchasers often don't really know which type of cellular IP camera suites and would satisfy their needs. As a result, they get sucked into buying cellular IP 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 situated in? (Hallway, outdoor, low light or excellent); what accuracy of data do you want to get? (HD images with or without sound) & most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Certainly, this feature will depend on the surroundings where you want to use the camera.
A broad skillet and tilt range is never a poor thing.
Thirdly, zooming capability of the wireless IP camera is also essential.
Ensure that you check the kind of zooming ability, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the gear before purchase.
This is vital, especially when you are buying from your local electronic digital store.
Always obtain a test set up as this will permit you to determine the display quality of the camera.
In addition, it will offer you an opportunity to learn how to create the gear in a proper manner to make sure that you receive the best image and audio tracks quality.
