You’ve checked out a variety of several surveillance systems and the one that hit your sweet spot is a 4-Channel Wired USB DVR Complete System. But the question is, do you really need it?
Parts of the Wired USB DVR System
Let’s start basing your needs on the different components of a 4-Channel Wired USB DVR complete system.
USB Stand-Alone 4-Channel DVR
DVRs are usually known as more efficient compared to VCR receivers. With VCR, your videos are sure to have poor image and audio quality. Moreover, a VCR can’t work with multiple cameras at the same time. You will have to switch from one real-time video to another.
The four-channel bit will sweep you off your feet. This means the system can only work with four channels and no more than that. If you have more than four cameras installed in your home or office then you might need an 8 or 16-channel system instead.
Finally, we get to the “USB stand-alone” function of this system. This means that you’ll only have to plug the device via its USB for the DVR to work. It’s as easy as that.
Wired Bullet Cameras
Bullet cameras are apparently small in size, which makes it easy for you to create hard-to-reach hiding places for them. This is a must if you don’t want thieves or vandals to destroy them right after they break inside your property.
Wired DVRs basically entail that you’ll have to connect the wires to other devices in the system to make sure they’re all interoperable. Wired systems are more physically taxing in terms of installation, but at least you won’t have to figure out network configurations for them.
Lastly, let’s check out its image recording options. Its day-night capabilities enable the cameras to automatically detect light levels and adjust accordingly. During the day, your camera would record footages in full color. When day turns into night, the camera will then switch to infrared lighting and shoot in black-and-white mode instead.
100-Foot Cables
Complete systems, of course, include cables. But if 100 feet is not enough to have everything connected, you’ll have to purchase extra.
LCD Monitor
A DVR surveillance system is incomplete without its own LCD monitor. The size varies, however, depending on the system specifications of your provider. If possible, avoid using CRT monitors with your system because they not only consume more power but their rendition of image is also less accurate.
Other optional components for your 4-channel Wired USB DVR system would be a mouse and remote control unit.
