Searching for IMX178 and IMX185 cameras, I came across www.ccdcam.com Has anyone ever tried them ?

I bought an IMX 185 board from hscctv.com and have tested it for several months now. The sensor is very good both day and night but the firmware can not utilize the full potential as the automatic day/night switching only works with a minimum exposure time of 1/25s. It also can not be set up...

My question was not for complete cameras, but for the boards because I would like to chose a good CS-mount lens , assemble it myself and put it into a homemade stainless steel outdoor enclosure.

Has anyone tested board type cameras based upon IMX 178 or IMX 185 and sold on aliexpress for USD 100 ?

I was wondering how many BI licenses have been sold and the worldwide distribution of users.

My preference is less resolution and a larger sensor. Unfortunately larger sensors are only used in expensive cameras. A 1/2" sensor 1080p is much more useful with low light than 1/2" sensor with 4Mp . resolution. Usually the larger each pixel is, the better the performance.

12Mbyte is the total (400kbit to 2,8Mbyte per camera). The system is working fine and has been doing so for over 9 months. You mention offloading the cameras to another recording destination. I have not found this option in BI. Fenderman what is Your guess of a meaningful limit for BI...

12MByte, 9 cameras, yes MB:Asus Z97 Gryphon,,not yet, 7 professional, worst case 50% I7-4790K 16GB Ram There is nothing wrong IMO, just where are the limits of the disk-caches ? Its not the actrual writing but the transfer of cached pretrigger frames to the disk.

Fenderman, I agree however even when an SSD is used (I am using Intel 530) this is the limiting element. Have You experimented with parallel SSDs for such a case? Or is the SATA mangement the limit? Or a PCI based storage ? Some kind of cache memory would be helpful. Instantaneously...

IMO the limit of BI is the writing speed with multiple cameras and a high pretrigger frame count, when direct to disk is used. In case of multiple cameras triggered, frames of some cameras get lost long before the I7 processor has reached 100%. Maybe a good measure of the workload is the total...

The LEDs I use are Oslon SFH4715S and my source is RS-components. Performance is very good up to 8 meters. Of my homemade IR-illuminators none has failed since installation a year ago. Nor could I detect any degradation. You have to reflow-solder them and put them into a watertight and heat...

Using separate IR-illuminators reduces backscatter from fog, rain, snowfall or cobwebs. I built IR-illuminators myself using 3W SMD Oslon IR-Leds mounted to Bergquist plates. Drivers are MeanWell LDD1000h. It took me many hours to build them.

To my knowledge,only 4 different trigger signals can be sent via serial to BI. 0 (no trigger) and 1,2,4,8.

Hi Martin_lario! It would be interesting to see your BI-screenshot with the motion- trigger-settings and then a screenshot of the arduino serial monitor.

The command is Serial.print(0) not Serial.println(0) perhaps this helps. BTW my Aduino-ethernet based BI-systems work very well.
