WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. While you hook up the IP camera to your router, you have to choose one of them, 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.
Wireless or PoE, which is the foremost? As a senior technician who may have four years in training video monitoring industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through wireless sign (2.4GHz UHF strap, 5GHz SHF group).
Obviously, after the IP camera helps WiFi, the camera can connect your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is the advantage of WiFi.
But there are two disadvantages on WiFi, that are; every gadgets require power, which means your IP camera still requires cable for connection.
Up to now, I haven't found any IP surveillance cameras are able to operate with power packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed 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 Wireless device, environment (interior or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters interior.
When Wi-fi devices will work outdoor without barrier, the transmission distance will be much way.
To extend the Wi-fi coverage or distance, you can install WiFi gain access to point. Such an access point (or hotspot) has a variety of about 20 meters (66 toes) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't 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 (Cat5/6) is the main feature of PoE technology.
So long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cams support plug-and-play installation, which greatly reduced the set up procedures, and eliminate the necessity of electric power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum power rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
In order to provide power supply 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 vitality.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Negatives AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable tv, there is absolutely no signal disturbance, no sign jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is essential 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 turn, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.
Ensuring the Wireless IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to manage, centralized electricity solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I found that Wireless IP video cameras are widely used for non-professional interior home security, and PoE IP video cameras are installed for outdoor security system. But if you choose WiFi IP Camera please read article below.
So how would you determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many purchasers 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 cellular IP surveillance cameras that are beyond what they need.
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 bright); what perfection of data would you like to capture? (HD images with or without sound) and most importantly, what's your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Of course, this feature will rely upon the environment where you want to use the camera.
A broad skillet and tilt range is never a negative thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Make sure that you check the type of zooming potential, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your neighborhood electronic store.
Always request for a test setup as this will permit you to determine the display quality of the camera.
In addition, it will offer you an possibility to learn how to set up the equipment in an effective manner to make sure that you obtain the best image and sound quality.
