A varifocal lens is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes, as compared to parfocal ("true") zoom lens, which remains in focus as the lens zooms (focal length and magnification change). Many so-called "zoom" lenses, particularly in the case of fixed lens cameras, are actually varifocal lenses. A varifocal lens. Left image is at 2.8 mm, in focus. Middle image is at 12 mm with the focus left alone from 2.8 mm. Right image is at 12 mm refocused. The close knob is focal length and the far knob is focus. However, some wireless security cameras are battery-powered, making the cameras truly wireless from top to bottom. cameras are proving very popular among modern security consumers due to their low installation costs (there is no need to run expensive video extension cables) and flexible mounting options; wireless cameras can be mounted/installed in locations previously unavailable to standard wired cameras. There is no need for a DVR or video capture card in order to broadcast the surveillance video over the Internet. IP video servers, also known as network video servers turn any CCTV camera (with a standard BNC output) into an IP based network camera (Ethernet output).

This customer purchased the item at our site.
The price at first caught me off guard and I did not want to buy this product but if you take a good look at all the specifications you would say it is worth it. I was especially greatly awestruck by the 10-50 mm variation. I have been searching for a lens like this for my security camera since 3 years now but have not really found one that was as functional as this one. And the technology of this lens is pretty advanced. Let me just explain how advanced and hi-tech this is. Instead of the traditional zoom lenses that are twisted sideways, there are knobs. 2 knobs for 2 functions and I am all up for modern and unconventional technology. This lens’ other great advantage is the cable that comes along. I found that heartily useful and even the length was perfect.

I always really pay attention to such little details of the products I buy. Many overlook this fact but it is those little “unimportant” things that aid and assist you greatly.

You must check the box to enable P2P function and then click Apply to save at bottom of screen.


Make sure that your NVR/DVR is connected to your modem/router with a CAT5/Ethernet cable. Once P2P has been enabled please go to TCP/IP section inside of the network screen. Enable “DHCP” inside of the Network settings and save. Once DHCP has been enabled you will need to reboot the system.


Upon rebooting navigate back to the P2P setting to the system and scan the code with your mobile iMaxCam app and from this point you should be able to see the cameras.

Step 2: Tap the menu icon on the top left corner to access the menu as shown in the picture.

Viewing the live camera feed from your Integrator Series Network Video Recorder, or NVR, through a mobile device is simple, and can be done in less than five minutes. If you have used our G4MX App you will find it’s very similar, but if you haven’t, that’s okay too. As in the tutorial for iMaxCam, In this short tutorial we’ll be showing you how to setup your live security camera feed on your mobile device via the peer-to-peer, or P2P method, using a QR Code Scanning setup. Think of it as allowing your camera server and your mobile device to meet up and communicate together in the cloud, just by using a bar code your device can read. No Port-Forwarding or IT specialists needed. On your NVR, rick click to login to the main menu. Then select “System”, then “Network”, then click the box marked “Enable DHCP”. This should allow all the forms to be automatic when you connect your device. If you would rather set your IP address manually, you can do that as well. Just leave the “Enable DHCP” box unchecked and you will be given an opportunity to set your IP address yourself. In the setting page you’ll see the QR code. Leave that up on your screen, because you will need to scan it with your mobile momentarily. On your mobile device, download the “EZView” App from your preferred app store. Once downloaded, go ahead and open “EZView”. Select the main menu icon in the top left hand corner. Then select “Devices”. This is where you can add new devices and manage existing ones. Now that you have your device page open, you will need to add a new device. To do this, select the “+“ in the top right corner. Select “Add By P2P” to change the registration mode. Be sure to name your device (any name that works for you), then tap on the QR code icon to scan the QR code displayed on your monitor. Once you’ve done this, all of the information for your NVR should appear on your mobile, with exception of your user name and password. Go ahead and enter your login details there if prompted. After Inputting the information above select “Start Live View” at the bottom of the page to complete the setup and begin viewing your camera’s live feed!
