Q:Buy monitor camera attention to what

Due to the manufacturers in the DSP and related technology between the level of differences, so the product is also different, so the parameters are marked with the gap, and some marked 500 lines, and some standard 520 lines, there are marked 530 lines, the highest marked 540 lines, Even 600 lines. So a variety of line number classification, in fact, shows the differences between the various, of course, which also mixed with a small amount of domestic enterprises to 480 lines fake 500 lines above the product composition. In fact, even in the same 540 line products, because the manufacturers of production technology differences and DSP technology differences, the same line of products with different results. But with the naked eye to distinguish is more difficult to compare out, unless the professional testing equipment or image magnification to distinguish, or find one or two real high-end brand camera to contrast. But in essence, 520 lines or more are called high-definition cameras, but analog cameras in the existing DSP and manufacturing technology based on a limit upgrade, it will be the traditional 480 line HD standard to 520 lines Or 540 lines.

Q:Remote monitoring principle

Network communication using TCP / IP and network multicast (Multicast) technology, to maximize the use of the network transmission performance and network bandwidth, to avoid network congestion.

Q:3 megapixel surveillance cameras store much day

3600 seconds (per hour) * 24 hours (per day) * Rate (128kbps-8Mbps) / 8 (conversion of bytes and bits) / 1024 (converted to M) / 1024 (converted to G) ≈42G (bit rate is 4Mbps)

Q:Monitor the camera's 4-way, 8-channel What does it mean! The

4 Road, 8 Road refers not to monitor the camera, but the number of hard disk recorders. 4-way hard disk video recorders can take up to 4 cameras, 8-way hard disk video recorders can take up to 8 cameras, in addition to 16, 24, 32 and so on.

Q:Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?

The voltage is constant, the current is not increased, such as the camera comes standard with the adapter power supply is 12V / 1A, if the switch for 12V / 5A or 10A, 20A power supply is the same, will not have any impact on the camera. The actual operating current of the camera does not increase as the power of the power increases.

Q:Monitor the camera hemispherical gun shape which is good

Both are different from the installation site, the dome camera is only installed in the indoor site, gun camera can be installed indoors can also be installed outdoors.

Q:Surveillance video can only save 4 days (the original can save about 15 days), is not the hard disk video recorder is a problem?

You are not modified to save the format of the ~ !! You can choose to format the hard disk ~ !! Clear all the contents of the inside to see
