badbeats310 0 Posted July 18, 2007 been using ASIM long range volumetric and curtain PIRs in the past to tie in with ADPro DVRs, and I've been looking for something that does the same thing but doesn't cost quite as much. I guess its because they're made in switzerland? Share this post Link to post Share on other sites
kensplace 0 Posted July 18, 2007 Not actually installed one yet, but bought a couple of second hand optex redwall sensors, the ones I got are quite well built, pretty much all metal apart from the front sensor window, which has a rain sheild. Was not keen on the fact that the side panel that you unscrew to get at the connections is made out of plastic, which kindof defeats the purpose of having the rest all metal if you are going to protect the connection side with plastic... The side panel is tamper protected, so if the panel is unscrewed, you can detect that. They seem to be used quite a lot where I live (uk) I see quite a few on building sites, and the local park has them on both the fixed and the ptz cameras (although the local park protects the 'reachable' optex redwalls by having them in a metal wire cage, probably a sensible move) Wiring wise, they seem easy enough, nothing special, or difficult. Cant comment on the range/sensitivity as not installed them yet, but the local park has them covering large areas. The ones I got were used, and the paintwork was bubbling/coming off in places, so obviously the paint was not up to the job of long term outdoor use, even though they looked like they had been well painted. I just to sanded that off, and re-spray and at the end of the day, it would not have been anything other than a purely cosmetic problem. May be worth checking to see if the latest sensors offer masking detection, especially if you are going to use them in a high security application, and there is a possibility someone may attempt it.

badbeats310 0 Posted July 18, 2007 Ya I've seen the Redwalls before. They Look pretty heavy duty. I mean they're all basically simple in design and installation, just don't know why they cost so damn much. The ASIM long range units we were using were close to 1200usd !
