Yes. All of our DVRs and NVRs come with both VGA and HDMI video outputs. This allows you to connect your system to your HD TV or virtually any other type of monitor. You can also use both of these outputs simultaneously to view your cameras on two different monitors or TVs.
Why image seems to be blurry at night for app, but TV not?
It is normal, because the transmission of the resolution for APP monitoring is CIF, the frame rate is 6fps, and it is 2CH D1+6CH CIF/8CH 960H on TV real time monitoring, the frame rate is 25fps, then it is normal to see the image seems to be blurry at night vision.
Ansjer security recorders can do five things simultaneously. First and foremost, they will record footage. At the same time, you can view the live feeds, playback recorded footage, backup important files to a USB stick, and remotely control your system from your smartphone or tablet - all without affecting the live recordings.
You can download video footage to a portable USB drive or an external USB hard drive. After inserting your USB media into the USB port on the DVR or NVR, right click on the live view to bring up the main menu (you may have to log-in at this point).
Next, click on the "Backup" menu option. From there, select the channel and start / end time that you would like to backup. A list of files should then appear. Click the files you would like to backup and click start. Your clip(s) will then begin to download onto your USB media.
What does Pre/Post Alarm recording mean?
Pre and Post Alarm Recording allows the DVR to be configured to record before and after an alarm has been triggered.
CCTV analog cameras connect to a video monitor or DVR using a coax connection, while IP cameras connect directly to the network using a RJ45 connector and have their own IP address. CCTV or analog cameras transmit analog signals over the coax cables, while IP cameras transmit digitally encoded video over a standard network cable. IP cameras have computers and intelligence, so they can be shared by many PCs using web browser and the video recorded using video management software or a NVR.
4K IP cameras are defined as having at least 4,000 (4K) horizontal pixels. Some of the cameras that are touted as 4K don’t actually meet the specification. Typical high resolution 4K cameras provide over 4,000 pixels, but actually operate best with a resolution of 3840 x 2160 pixels. 4K cameras from Sony, Samsung and Hikvision all meet the 4K requirement, while Axis cameras have less resolution, but still say they are 4K. It is best to check the details before selecting a camera and take a look at our review of 4K cameras.
An IP camera system consists of a number of network attached cameras, which are generally called IP cameras. The system also includes some type of video recording system and a number of viewing workstations. The video recording system can be either a computer running video management software (VMS, or a Network Video Recorder (NVR).
The latest IP cameras get power over the network. This is referred to as Power over Ethernet (PoE). You can also add a PoE midspan or power injector between the switch and the camera. This means that you only need to run one network cable to each camera, making installation very easy.
