You'd better know what you're doing if you want to get away with it! However, it does exactly what it says. You'd better know what you're doing if you want to get away with it!
Pros:
- The picture quality is above average and the price is reasonable.
- As stated, it is compatible with AHD, TVI, and CVBS.
- There is a 12vdc Aux out on this device.
Cons:
- The menu is not very user-friendly (at least for Americans).
- I've never seen a more useless manual.
- Is a little too big for use on a tall ladder.
- Because of the inefficient DC to DC conversion circuit, the battery will not last long if you use the 12vdc output. br>br>Conclusion: br>br> br>The RS485 connection was not tested. This monitor does exactly what it says it will and at a reasonable price. br>It's not particularly user-friendly, and it has a few quirks that you'll have to live with- In order to see them, you must connect them in the correct order. The manual is a joke, so if you don't have decades of experience in the CCTV field (as I do), you should spend a little more money and get a more professionally designed unit from a reputable brand. (i. e. g. , Triplett, Tenma, HikVision, and so on. ).

Having done a lot of installations, I've found that this isn't very useful - as the case may be. The problem is that if you bench test the cameras and get to know your mounts, you get pretty good at "guess-work. " As you make some rough adjustments higher up the ladder, the camera will see "mating. " Which is a good thing. because it's rare that you'll be able to access the wiring after the camera has been mounted. Duh. In any case, there are times when you need to check if you have the right camera for the job, or you can use it to quickly test a number of units to see if they work at all. Use in the real world is limited - That's all I have to say about it. It may save you some time, but don't expect it to solve many problems that you couldn't solve on your own.

br>br>The screen also sparkles from time to time, I believe, due to the scaler. br>br>However, it's a useful diagnostic tool that spends the majority of its time at the front door, displaying what's on the camera on the other side. br>br>Seems to prefer CVI over the other formats that my front door camera produces.

The battery life is pitiful, and the USB power source is insufficient to keep the screen lit. So all you have to do now is wait for the battery to charge. Bummer.

Before I connected them to the system, I was able to adjust them to my preferred view. I was able to use it at work as well when I needed to set up four cameras to monitor entry ports to a gate.

I was under the impression that I was getting a good deal. I needed something compact, light, and capable of HD testing, as stated in the product description. It was a 1080p analog camera that was directly plugged into the BNC out. Because there was no way of knowing if the focus would be satisfactory for the client, I had no choice but to pull out the clunky giant old monitor I carry for these cameras to make out the focus. It turned on, which is a lot better than the other $80 monitor I ordered. Spend a little more; you'll be glad you did.

The battery life is extremely low. It's fine if you're only working with a couple of cameras. However, if you're working with eight cameras, you'll need to charge.
