I have used a total of 7 of these exact units and never had any problems. I have used the generic unencrypted readers on some units, and the H.I.D. Brand card readers with encryption on others. Neither gave me any problems during set up.I did have one unit that lost the ability to connect with the software computer, but after simply reinstalling the program I haven't had a problem since. I have noticed Amazon is now selling an identical unit marked with the brand MENGQI. It looks the same, but I am always concerned that something will change.

Very happy with the product. It was difficult to get the controller to work at first because the link to the software wasn't working. However, I was able to find another link that lead me to finding the software. Everyinis functional and working, door latch and card scanner works. I'm using HID MiniProx plus reader and the UHPPOTE door latch. I also bought the fire alarm module, very good build quality waiting for more stock to purchase.

Im Prinzip erklärt sich der Anschluss der Karte von selbst. Der beiliegende Anschlussplan ist aber für den Anfänger sicherlich hilfreich (engl.). Die beiliegende Software ist auf englisch, dafür aber kostenlos. Wer googlen kann findet eine deutsche Anleitung. Die Programmierung gestaltet sich dann auch für den Anfänger problemlos. Kurzum Platine und Software ok.

No le pongo 5 estrellas por que me he tenido que buscar yo la vida con el software. Pero con un video que vi de 30 minutos en YouTube, eché a andar el aparato. Y el aparato en si, es sencillamente maravilloso. Tiene más electrónica la tarjeta de red que el propio controlador, pero funciona excelente. Aun no se donde está el truco y la diferencia con equipos de 800€.

Tout y est! connecteurs de bonne qualité, logiciel complet avec un léger bemol : on ne peut pas remettre à zéro l'historique. il m'a fallu casser le mot de passe de la base access pour pouvoir supprimer les enregistrements. Manque un API pour les développeurs mais là je chipote. Un autre détail : il manque la possibilité de déporter les Leds sur une façade de boitier (un connecteur aurait été la bienvenue) Néanmoins ce produit mérite les 5 étoiles.

There was no way to make it discovereable by the computer, tried conecting it directly (RJ45) to a PC, thru the local network, thru the wlan, but no luck with any of those, there a no guides on internet, the provided software has more than a decade, I waste my time, a technician which I hired time and a lot of money. I have already wrote the seller for help, hope I be able to come back soon with good news updating the review, but for now I do not reccommended even if you are a technician with knowledge about wires and networks.***UPDATE***I contacted seller, they made all they can to help me, it has been one of the better experience in customer service I have ever had, now almost everything is working like a charm, but now I am sure they will help me have the best experience with their product, I highly reccomend them, would be useful if they ship the board with a few more instructions

This is an update based on using this for some time. I've changed my rating to three stars instead of four, because the software is just absolutely horrendous with zero support. Currently, we're unable to get it to create any open/close reports at all. No matter what is selected, no activity shows in the report. You can see it in the log, but can't export it. We also can't open the DB file directly either, it has a password. So basically the actual control works just fine, reporting is totally useless. Oh, and every few months we get an error and have to reinstall the software.Original review:This is a very good controller. I'm comparing it to a couple of name-brand systems I'm familiar with, and it compares pretty well.Obviously, the hugest advantage is the price. This costs around 1/8th of the price of the cheapest two-door kits from major companies. And it's not just the cost of the system, but the name-brand kits force you to buy only their cards/fobs instead of industry-standard cards and fobs. They typically cost four times more, and limit your choices to whatever they make. For example, this is replacing a Securakey system that doesn't allow for any stick-on tags at all, and their cards cost over $2 each while I can get industry-standard ISO 14443 cards for 30 cents each.Setup was pretty easy. While the hardware documentation isn't great, it's clear enough to figure out the connections in a few minutes. I had the controller running and reading cards in about 15 minutes. The software installs easily. The documentation for the software is VERY bad, just awful, but luckily the software itself works just fine and is easy to figure out. Actually, it's more intuitive than the name-brand stuff I'm familiar with. There is also an "extended mode" with extra features that you can enable with the passcode "5678" that adds useful things like time-based access control. The software auto-discovers the device on the network and instantly configures it. Unlike most major systems that force you to pre-program them with a serial device.Cons... There is no internal battery backup. Not a big deal, as you have to provide backup for your maglocks anyway, so we put everything on a 1500va UPS. The board ships by itself without a case, so you can buy a simple plastic project box for it or pick up a standard wall-mount equipment box on Amazon for $27. That's what I did. Cheap solution. The software works, but the vendor says there will never be upgrades available for it. So there is some risk that future versions of Windows won't work with it. Not a big deal for us, as we run virtual machines and will just leave this running on a VM with Windows server 2008 forever.Overall I highly recommend this. Pair it up with any Wiegand-24 readers and any maglocks for a full system. I picked up a cheap wall-mount power supply here on Amazon to power this, and $20 card readers that work with Mifare/NFC cards which are dirt cheap. So my total system price for a couple of doors was about $400, where a comparable Securakey system puts you around $1300.

Esta muy bien descrito, es muy útil y tiene un precio asequible.Se programa muy fácil aunque las instalaciones están en i

I am very skeptical when I see the word "professional" in the product name. However in this case it is very appropriate. The controller would be very relevant for a medium size company. The software is very impressive can handle many controllers simultaneously, with features such as zones, floors. departments etc. It even has time attendance feature in case you need it. This version of controller can handle two sensors and if you set it one on the entry side one on exit the software tacks the length of time users spend in the building and tells you whether someone is in the building at any moment of time. Please be aware that you have to install a secondary exit feature such as a push bar or an exit button to comply with the fire department requirements. The software can be set up to log the exits by the push button but naturally in this case you loose the ability to track users' exits.The English version does use some funny language though. but I find it pretty complete and well done.One thing to note: You need card readers sensors. I used this one: http://www.amazon.com/gp/product/B00AUB2RQ4?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_15The instructions say connect white or yellow wire to a specific pin on the board. In my case when I connected white the controller pretended working, beeped on card swipes but refused to recognize them. When i switched to use the yellow wire everything started working normally.The bottom line: I am impressed with the controller and hope the reliability wold stand to the "professional" name..Update:4 years later the controller is still going strong despite a pretty heavy everyday use in a commercial setup in far from ideal environment..
