Problem: Vehicle Blurred Entering Garage
I would like to ask for feedback on an installation issue I have with one camera. In a nutshell, its a camera that monitors a garage entrance from the inside so sees vehicles entering and leaving.
Whilst the image is very clear of the driveway, any vehicle that entry or exit is just a blur [IPVM Note: See Camera Slow Shutter / Ghosting Tested]. The camera model and position is not suited to this function. Some other causes could be drastic light differences, headlights and vehicle speed.
This maybe a good exercise/discussion for people who have done and will do the IP video course.
I have compiled some photos of the area, dimensions, and then snapshots of the camera view from VMS client and web interface. I also have the camera settings and VMS settings.
Let me know and I can provide a PDF of my initial survey.
How's the lighting in the garage? Sure this isn't just motion blur caused by a slow shutter? Is the camera blurry when the car is parked as well, or just while it's coming and going?
Here are some more details. Matt I think nailed it on the head though and were my thooughts as well. Here are some more specifics on the area. As I have learnt more from the IP Video course I beleive I know where to aim.
Camera is an ACTi TCM 3511

Matt Ion mentioned adding a speed bump. A series of urethane types will slow vehicles down <5 MPH, and they are easy to install. However, they may not hold up to aggressive use, dam stormwater, be the cause of car backups into city streets during busy hours, or irritate garage patrons.
Is this a new scene, different from the first?
Does the gate open/close on every in/out?
Watch out for auto-exposure readjustment latency after lighting changes, some cameras are slower than others.
Is that the only/best pinch point? IMO pointing the camera towards a gate which will be opening/closing, allowing wildly varying amounts of backlight in, at the same time you are trying to get a good license capture is challenging...
Maybe work backwards, with that original scene, gain the camera to the max, then slow-down the shutter speed til you hopefully get a good capture. Post that PDF you mentioned...
And if all else fails: Call GhostBusters!
(new tag line for Raytec?)
Vasilles, again, is this problem happening in color mode when it is bright / light out? Your image above indicates that.
Also, you say this is an ACTi TCM-3511, which has built-in IR. Is the IR turned on?
From what I have seen so far this may indicate it is now a slow shutter issue.
Please answer these questions above.
Yes the camera is in color mode. I will attempt to put it in black and white mode. I tend to agree with you on the slow shutter speed.
Here is some more data hopefully the info comes thru. I did play turn on IR
Below are the VMS settings.
Vasilles,
The camera configuration indicates you are using a slow shutter, maxing at 1/5s which will certainly create quite a blur:
Increase this to, at least, 1/30s, higher if it's still blurry. And make sure the IR illuminator is on.
Btw, are the VMS settings from Milestone? Is the VMS actually over-riding / setting shutter speed / gain control?
VMS is OnSSI RC-E. Not sure if it is overriding the camera settings. I've not yet mastered OnSSIs product.
