2. Precautions
2.1. Guidelines for Avoiding EMI and ESD
1) CAT-5e cables or above with S/STP shielding are recommended.
2) Using shielded cable can avoid electro-magnetic interface. Shielding layer of the cable should conduct
to ground nearby and not until stretched too long. When many devices need conduct to ground, using
single point grounding to avoid earth loop.
3) Try to use camera cables that are the correct length. Avoid coiling camera cables. If the cables are
too long, use a meandering path rather than coiling the cables.
4) Keep your cameras away from equipment with high voltage, or high current (as motor, inverter, relay,
etc.). If necessary, use additional shielding.
5) ESD (electro-static discharge) may damage cameras permanently, so use suitable clothing (cotton)
and shoes, and touch the metal to discharge the electro-static before operating cameras.
2.2. Environmental Requirements
1) Housing temperature during operation: 0°C ~ 45°C, humidity during operation: 10% ~ 80%.
Storage temperature: -20°C ~ 70°C.
2) To avoid collecting dust in the optical filter, always keep the plastic cap on cameras when no lens is
mounted.
3) PC requirement: Intel Core 2 Duo, 2.4GHz or above, and 2GB memory or above.
4) NIC requirement: Intel Pro 1000 NIC or higher performance Gigabit LAN confirming to IEEE802.3af
standard, CAT-5e or CAT-6 cables, less than 100m, Gigabit Switch confirming to IEEE802.3af
standard.
5) Make sure that cameras are transported in the original factory packages.
2.3. Camera Mechanical Installation Precautions
Camera installation requirements:
1) The screw and camera have a screw length between 3 and 4.8 mm.
2) S
crew assembly torque ≤ 5N.M. If the screw assembly torque is too large, it may cause the camera
thread stripping.
2.4. Certification and Declaration
1. CE, RoHS
We declare that DAHENG IMAGING MARS GigE digital cameras have passed the following EU
certifications:
