Good question, Jeff. I would say that maybe there's a stuck in the last quarter, we were looking at things getting better and then the Omicron comes in, travel is restricted, and we use the what traveling very broad sense. We look at travel two ways. One is, you can see customers or the customers can 't come to you. Second thing is you have to do installations. Many of our products, they need a sign off by the customer after installation or some of the other support that has to be built, civil works, other things. Because of all this activity restriction, which become a problem. And just to give an idea, if we have to go back to, let's say, Asian country or to Middle East country to install it, we have to send a person from England, that person has to be quarantined for a couple of days, then they go back and they want to get the installation done and then they find out that the customer has got COVID, so the customer is not there, then they come back to the hotel, then they are quarantined again, and then they come back to England, they get quarantined again. So by the time you finish, it's a very in efficient system. And that has put some cost structures in it and some of the revenues have been pushed out. And that thing isn't going to change. Your guess is the guys would have mind. Every indication is Omicron is at peak, it's going to come down, that should open up. There's lot more positive, encouraging news. Just hope that there is not another variant that comes in. So to us in the security business, especially, customer interaction is very, very important, especially in the international sector. And it's also happened in the U.S. Some of the U.S. customers are also having a tough time visiting our sites or us been able to go back and sign off. So all that stuff is really the thing under the name travel. That has been a big issue, and hopefully, as it gets better, Omicron goes -- peaks down, we will again end up getting lot up successes and sign-ups with the customers.
