How was the video quality...the walmart and target video ive seen is beyond horrific. They are using 10 year old systems...shame.
Last six years I've worked 3 different counties with 4 different stores. I've found their Interior cameras provide minimal quality. Most are PTZ that revert back to certain areas of coverage when not being actively monitored. At MOST 1080p with VERY basic recognition, skin color, clothing, possibly blurred tattoos and enough definition to make out some items in their carts (some would just fill the entire cart with shit and just walk right out). I'd imagine 6-12mm lenses at the very most.
Exterior cameras are much more improved. Good enough to catch license plates at most any time of day. One store actually had a single lane driveway to get in and out of the parking lot and actually had a really nice bullet camera to get all plates exiting. Pa Vehicle Code only requires reg plates on the back bumper not both back and front like NJ. So they used one camera on the corner of the building angled down that driveway and toward the road to catch plates of all vehicles exiting the grounds as they drove away.
Most Walmart LP workers I've dealt with were trained extremely well in their VMS so when we arrived they'd basically hand us a list of the item(s) taken along with a DVD of all the clips sequentially clipped together from the suspect entering the store, committing the theft and their subsequent exit. Once outside one of the non PTZ exterior cameras would record the color style and model vehicle they'd get into. At that point the last clip was video of that vehicle driving out of the parking lot and a high frame lens covering the exit would get the plate.
Once we have the vehicle registration it's just a matter of getting the vehicle owners info, finding out where they live and comparing DL photos of occupants of that residence to the security footage. Go to the house for positive ID and boom, charges filed. Usually if you took photos and showed them to the suspects they'd come clean and just plead guilty once they were charged.
