What should I expect

From what you're saying, it's possible that the police department has a warrant out for your arrest. This can come up any time that law enforcement runs your name in their system - such as if you're pulled over for a traffic stop. With that being said, your best bet here is to contact an attorney who can speak to the police department for you, find out whether or not there is an active warrant for your arrest, find out what the charges are against you, and potentially arrange a voluntary surrender to clear up the warrant and start fighting the case.    As far as what you may be charged with, from what you've stated it seems that it's possible you may be charged with petit or even grand larceny depending on the amount of money that they are alleging you stole. With that being said, being charged with a crime does not give you a criminal record in and of itself. After you are charged and arraigned, your attorney will be provided discovery materials related to your case, will be able to examine the evidence and discuss it with you, advise you on what viable defenses exist as well as the potential for plea bargaining with the District Attorney's Office for a favorable resolution to your case. Understand though, that the simple omission of video does not necessarily mean that you can't be charged with a crime. Oftentimes people are charged with a crime where there is not direct evidence such as video or DNA, but rather they are charged with circumstantial evidence such as your pin code having been used to open the register when the money went missing.    At any rate, from what you've said you may be at risk of being arrested, so you should definitely consider consulting an attorney who can fight your case for you.
