Introduction
This section lists a few common issues that you might face and how to fix them.
Q. How do I stop the door being counted?
A. If the movement of a door is generating a target, which is then crossing a count line, or entering a zone, then you simply have to move the line/zone away from the movement of the door. Note if your device is installed too close to the door, and the door swings right past the device itself then moving the line won't help. You'll need to physically move the device itself away from the door.
Q. If I walk through the field of view with my hands out, it counts extra, how can I stop that?
A. Don't walk with your hands out! In all seriousness, if your intention is to trick a Vector into counting extra then you probably will be able to make it do that, but in real world application where people walk through normally they should be counted correctly.
Q. If I walk through the field of view holding my laptop in front of me, the laptop generates a separate target which gets counted. How can I stop that?
A. If you are configuring the device and holding your laptop to see what it does as you walk through then you may see this. It is recommended to place your laptop down to the side of the area and watch it from afar without carrying it in order to allow correct line placement. If you're seeing this issue in a real world application - for example, people entering a meeting room with their laptop ready to present to the board - you can tweak the lines, and/or adjust height filtering on the corresponding register, Alternatively you can remove any errors inadvertently added in this way to an occupancy count by using the various timeout options, which may be appropriate for a lot of applications.
Q. I am occasionally missing children, how can I be sure children will be counted?
A. Children who walk through the field of view by themselves should be counted fine as long as they are not purposely excluded by using the Height Filtering options (Global, or by Register). But any small child who is being carried through the field of view will not be detected as a separate target. Unfortunately, if a small child is walking very close to a parent they too may not generate enough signal to be tracked as a separate target. This is something to be expected.
Q. At the end of the day I can see that my IN and OUT counts are not the same, why not?
A. This is a common question and, of course, when a building is closed and therefore known to be empty, the ideal situation would be that the IN and OUT counts would be exactly the same - everyone who entered, also exited. But the reality is somewhat different and there can be many factors preventing IN and OUT totals from being equal. Firstly, this relies on the IN and OUT counts being 100% accurate and unfortunately, no People counting system can ever be 100% accurate, for 100% of the time. Due to the inaccuracies in all people counting devices (no matter how small), it is entirely possible for the number of people leaving an area to be recorded as more or less than those that entered the area. Additionally any configuration issues, or less than optimum installation may lead to people being missed, and/or things like doors or other non-human being inadvertently counted. Secondly, it is easy to miss a door that can be used to enter or exit a building in in these cases it is possible that someone could be counted IN but not counted OUT, or vice verse. Unmonitored doorways, like staff entrances, warehouse back doors, etc. can skew the IN and OUT figures.
