Upgrade Your Security Camera's Vision with the M7 Lens Sample Pack
Finding the right lens for your security camera can be challenging—different focal lengths affect the field of view, zoom, and clarity. Our M7 Lens Sample Pack lets you test multiple options before making a final decision, saving you time and money.

------------------------------------------
Two Convenient Options:

Short Focus Kit (2.8mm, 3.5mm, 3.7mm, 6mm)
– Best for wide-angle surveillance, covering large areas like parking lots, hallways, or backyards.

Medium Focus Kit (8mm, 10mm, 12mm, 15mm)
– Ideal for mid-range monitoring, such as doorways, driveways, or retail aisles, with less distortion than ultra-wide lenses.

**Need to choose the right filter? Let us help!**

Infrared radiation can affect digital sensors, causing unwanted color casts. That's why most digital cameras include an infrared cut filter.
We offer the option to add an infrared filter (650nm IRC) at checkout to give you maximum flexibility.

OPTIONS:
- NO IR FILTER
- WITH IR FILTER

**NOTICE:**
The sample package defaults to including an IR650 filter.
If you need a product without the filter, you can choose other listings in our store or contact our customer service for assistance.

**Important Notes:**
1. Lens Holder Compatibility:
- Match the holder height to your lens specs for proper focusing.
- Ensure the holder pitch matches your camera board.
Need help choosing? We're here to assist!

2. Manual Focus Features:
- The lens may feel loose before focusing - this is normal.
- After focusing, you can secure it with damping grease if needed.

3. Dust & Bubbles:
- You may notice dust or bubbles during focusing.
- They'll disappear once the lens is properly aligned.

4. Focusing Tips:
- Avoid over-tightening the lens to prevent sensor damage.
- Use a video screen for precise adjustments.

5. NoIR Cameras:
- Select "NO IR FILTER" at checkout if you're using a NoIR camera.

6. Custom Crafted Quality:
- Our lenses are precision-made, often by hand.
- Minor imperfections may exist, but they don't affect performance.
