People counter is great. Its simple to install and use and is reliable. It does not have an on-premise option in the free version. It could be a good feature to have. I recommend you try it out for free. It helps in the restaurant industry. Density has a good reputation but you have to make sure you can get the support you need after the initial implementation. Our restaurant has a lot of people walking in and out so a computerized people counter helps us keep a good schedule for our staff. The ability to monitor density of crowds/traffic is very important in many situations, whether it be for safety or business purposes (i have used this feature at my work place). Sometimes I wish that there was more detail available but overall i am happy with how easy they make things simple! It's great if you are looking into areas where crowd monitoring will help your situation greatly by providing clear information about traffic flow etc.
