Einleitung

If your camera's motion detection is creating a lot of false positives, this guide will show you how to replace the infrared blocking filter.

The filter is responsible for blocking infrared light that comes into the camera lens. Once you have removed the lens assembly, you can remove the filter.

The glass filter is located inside a self-contained unit with a battery and cannot be removed from the unit without damaging it. It sits within the camera lens holder. Although the lens holder has two slots, only one screw actually anchors the filter to the lens holder.

A Phillips #0 screwdriver is required for the single screw.

Werkzeuge

Schritt 1

Grip the rubber ring with your fingers and pull up.
Rotate the Canary as you pull out one tab at a time.

Schritt 2

Use your Phillips #0 screwdriver to remove the four 6mm screws.

Schritt 3

Use the flat end of the spudger to carefully pry off the bottom casing.
Alternate pushing up on the left and right sides until the clips holding the case in are visible.

Schritt 4

Do not yank the bottom off or you may damage the ribbon cable or the ZIF connector.
Carefully remove the bottom casing by gripping it on both sides and pulling straight up.

Schritt 5

Use the pointed end of the spudger to flip up the small retaining flap on the ZIF (zero insertion force) connector.
Pull the ribbon cable out towards the device.

Schritt 6

There are two empty nooks underneath the bottom of the panel close to each side of the case.
Place the pointed edge of the spudger in one of the nooks under the panel and pry upwards.

Schritt 7

Adhesive will have to be reapplied after removing the panel.
Pull the panel away from the device.

Schritt 8

Use the flat end of the spudger to carefully pry off the top casing.
Alternate pushing up on the left and right sides until the inner clips are released.
Do not use too much force or the top may fly off unexpectedly.

Schritt 9

Pull the top casing away from the device.

Schritt 10

Use your Phillips #0 screwdriver to remove the two 5mm screws.

Schritt 11

Using a Phillips #0 screwdriver, remove the six 6mm screws.
The seventh screw in the bottom middle is not connected to the motherboard and does not need to be removed.
As you remove the screws, hold on to the motherboard to prevent it from falling and sustaining damage.

Schritt 12

Grip the circular part of the motherboard and pull it straight out of the device.

Schritt 13

Do not pull on the wires themselves as they are fragile and may break from the connector.
Locate the power connector next to the lens protector on the infrared LED board. Using your fingers, wiggle the power connector back and forth until it is loose.

Schritt 14

Find the power connector next to the buzzer that is labelled "MIC IR-LED". Use your fingers to wiggle it back and forth until it becomes loose.

Schritt 15

Remove the four Phillips #0 6mm screws.
Lift the heatsink up and pull it away from the motherboard.
These screws also hold the infrared LED board in. Be sure to hold it while you remove the heatsink screws.

Schritt 16

Lift the infrared LED board directly upwards and pull away from the motherboard.

Schritt 17

Remove the two Phillips #0 5mm screws.
Hold the lens assembly on the other side of the motherboard to prevent it from falling as you remove these screws.
