    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Does any one know what ETS stands for. They are definetly law enforcement. THis I know. Hayward PD also makes reference to ETS often being 'on scene', 'with subject', etc.. .

Electronic Tracking System, commonly referred to as "bait tags". They emit the signal once they're taken, usually from a bank or a business, although they can also be hidden inside of articles (such as bikes, toolboxes, etc).

Here's something I posted in another thread about a similar question, although there is some info specific to Sacramento Sheriff's Dept.:

The "check" with bars deals with bait tags. Those are the bait tags from banks, businesses, and bait vehicles the departments leave out. They are called "tracker" units, or RAM units (also ETS...there are actual ETS units that identify as ETS 1, etc... on the radio). They retain their unit # (like 12Adam3), but will say they're tracker equipped. The first unit to receive the signal will usually have an "on-view" made up, and units will head to the area and put themselves on the call.

When the towers go hot, the individual cars will begin receiving the tag signal, and the bars are the signal strength, and the display shows what direction relative to the patrol car the signal is coming from. A "full set" on the ETS (electronic tracking system) is somewhere around 10 bars. That means you're basically standing next to the unit.

Seperately, you have LoJack units out and about, but they identify as being "LoJack" or "LoJack equipped". STAR and AIR1 both have both systems. A "full set" on a LoJack is somewhere over 20 bars (don't know the exact #).

For the Alameda County SO it means Eden Township Substation. It is the substation up by Interstate 580 and 150th ave, that covers the west side of the county. So when Hayward PD says ETS is on the scene they are saying a deputy is on the scene.

1. ETS in Alameda County Vernacular does refer to the ACSD, Northzone absolutely is correct.
2. The 211 tag system is called Pro-net. When they first came out, Alameda County Officers were told not to refer to it by name on the air- Just make veiled reference to being 'equipped' if you need to. Most of the time dispatchers know who is and is not equipped by thier vehicle unit number when they log on via MDT. SFPD call them RAT packs which I believe stands for Robbery Apprehension Team as opposed to the device themselves.

The pro-net units themselves are a small box that sit on the dash of the patrol car. They are very simple and have a couple of buttons and an LCD Screen. They remain dormant until they receive a signal or are tested. Essentially, the LCD screen show the direction of the pro-net tag in relation to the front of the patrol car. This is determined via triangulation
from three HI band quater-wave spike set in an arrowhead formation on the roof of the car.

when the pronet units go off they have a whine and the arrow points to the bad guy. The lower the whine the father the distance to the activated pronet tag. when the pitch get really high and starts to warble instead of being a solid tone- bingo you are on top of him. The bars refers to a the signal strength meter broken into 5 segements on the lcd display- 1= lowest 5= highest signal strength.

Pro-Net is a company name. There are a variety of vendors out there that provide tracking equipment.

Oakland PD, who hosts regional training sessions, also refers to them as RAT.

Some arrangements have 4 antennas forming a square.

Some equipment versions in the cars have a 10 pt meter while the dispatch stations, which monitor the towers, have a 20 pt meter with geographic map that displays "hot" areas.
