What Are the Differences? IP, Analog, TVI, and WiFi Cameras.
Security systems are becoming a standard implementation these days. And understandably so — as technology improves and becomes cheaper and more accessible, security and peace of mind are one of the first prerogatives to become a basic necessity for the average citizen.
While many large institutions and buildings still rely on security professionals to install their surveillance systems, smaller businesses and homeowners often go for DIY setups that save time and money.
If you are installing and running your own security, you’ll need to know about the different types of technology available to you. Once you understand the differences between standard IP, analog, TVI cameras, and wireless models, you will be able to choose the best option to fulfill your security needs.
A standard IP camera connects to a Network Video Recorder or its network through an Ethernet cable. Once it is physically hooked up to the network (cabling can run up to 1500 feet), it can be accessed and used remotely from anywhere in the world as long as one has the IP address/password for the camera.
The camera itself can have image processing capabilities, and newer models often have advanced image refining features such as WDR (wide dynamic range), VCA (video content analysis), and ROI (region of interest). If you are looking for an IP camera with these features, see Anpviz’s Advanced IP IPC-B140H 4mm Fixed Lens 30 IR LEDs Bullet Camera.
Because the camera has to process the image however, there is going to be a slight (1-2 sec) delay in the transfer of the footage to your monitor. Unless you have an explicit need to watch things at the precise second they happen, this should not be an issue at all. Along with all the perks of built-in image processing, IP cameras can have up to 4k resolution. To see complete IP camera systems, click here.
An analog camera connects to its network through a BNC cable. The image transfer is instant because this type of camera does not process footage (only captures it), so you will experience no delay when watching in live view. But analog cameras have lower resolution capabilities than their IP peers because of their older form of technology.
Normally, cable connection for analog cameras can run up to 1500 feet; However, if you are looking to cover very large spaces/distances across multiple buildings, analog cameras may not be your best bet as underground cables are vulnerable to damage and interference.
In general, analog cameras tend to be much less expensive than their IP counterparts, so if you’re on a budget, analog cameras are the solid tried-and-true security option that’s been around the longest. If you are looking for a durable analog camera, see Anpviz’s 2.0MP AC3332W Day and Night Indoor Outdoor Security Camera.
A TVI camera is basically analog technology fused with high definition (up to 720p/1080p). Just like their traditional analog counterparts, TVI cameras connect to a network through a BNC cable and the image transfer is instant. Cabling for TVI cameras can only run up to 900ft, so TVI cameras are most suitable for smaller spaces and rooms that are close by to each other.
The selling point of a TVI camera is that it delivers high-definition resolution at a cheaper price. So If traditional analog cameras don’t quite reach the level of crisp clarity you need, but IP cameras are beyond your budget, then TVI cameras may be the perfect option for you. Anpviz does not currently sell single TVI cameras, but we do sell full TVI systems here.
If running wires is too much of a hassle for you, you can now go wireless with analog and IP cameras.
Wireless Analog Cameras
A wireless analog camera connects to its network using an RF signal that replaces the traditional BNC cable. Although it eliminates the trouble of wiring, wireless analog cameras tend to be not very reliable as the connection is easily disrupted by interference from cell phones or other wireless devices. Anpviz does not currently provide any wireless analog cameras.
Wireless IP Cameras
Wireless IP cameras are much more dependable than wireless analog cameras. Like a cell phone or computer, they can connect to Wi-Fi, and password-based security features ensure that your connection stays private. Their digital transmission is less easily affected by surrounding devices than their analog counterparts, although very network-complex areas with lots of signals coming from cell phones and routers can still cause some interference with the bandwidth.
The image quality of wireless IP cameras can vary based on the strength of the wireless connectivity; however, if you have a consistently strong Wi-Fi signal, this should not be a problem.Depending on the model, wireless IP cameras can deliver the same advanced features as standard IP cameras, so they are quickly gaining popularity in the surveillance market.
