WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. When you connect 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 whole IP camera system, you should analysis the assembly environment and investigate which functions you want to attain.
Wi-fi or PoE, which is the foremost? As a senior technician who has four years in training video surveillance industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cellular indication (2.4GHz UHF strap, 5GHz SHF group).
Obviously, after the IP camera helps WiFi, the camera can connect your router without needing hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of Wireless.
But there are two drawbacks on WiFi, that happen to be; every gadgets require power, 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 electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have many things to consider including power rate of WiFi device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters interior.
When Wireless devices are working outdoor without barrier, the transmission distance will be much far.
To increase the WiFi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range around 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over sole Ethernet wire (Cat5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP video cameras support plug-and-play set up, which greatly reduced the installation 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 electric power rate is to 15.4 W of DC electricity (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high ability ingestion devices, the IEEE connection 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 surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Disadvantages AND Positives OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable, there is no signal disturbance, no signal jamming.
For properly working of PoE devices, Vitality 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 move, which increased a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing 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 transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I found that Wireless IP surveillance cameras are trusted for non-professional indoors home security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wireless IP Camera please read article below.
So how do you determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many purchasers often don't really know which kind of cordless 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 need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what perfection of data do you want to catch? (HD images with or without audio) & 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.
Naturally, this feature will rely upon the environment where you would like to use the camera.
A wide pan and tilt range is never a poor thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the kind of zooming functionality, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
That is vital, particularly when you are buying from your neighborhood digital store.
Always obtain a test setup as this will enable you to look for the display quality of the camera.
In addition, it will offer you an possibility to learn how to create the equipment in an effective manner to make certain you get the best image and audio quality.
