Shany Electronic has upgraded the lens module and mechanism for the Outdoor IR Camera, MTC-L6438HQ, since 2008 Q3. In the upgraded MTC-L6438HQ:
1. we have taken a RoHS compliant Light Sensor to replace the original CDS Resistor.
2. To match f2.9~10mm varifocal lens, the original 15(5ø) LEDs have been changed to 13 (5ø) LEDs and added 2 Super High Power Reflection LEDs.
3. At the circuit layout of the lens module has been altered from series connection to matrix to improve operation temperature and prolong the life time of LEDs.
4. At the rear part of MTC-L6438HQ, the conventional cable gland and cable have been designed as an unity to enhance water resistance.
As a result, the upgraded MTC-L6438HQ has a superior IR working distance and a longer LED life time. It not only complies with the RoHS directive by using the harmless substances but also has a better water resistance.
