SMART 4 CAMERA SWITCHER
Model: APV4CAM
Brand: AERPRO
Category: HARNESSES
Type: OEM VIDEO RETENTION
The APV4CAM is a universal multi camera switch interface that enables multiple cameras to be connected to an aftermarket AV headunit or display. It features four RCA camera inputs (front, rear, left and right) and one RCA video output which connects into the video input on the aftermarket display. The inputs are voltage triggered determined by driver behaviour, with the rear camera input automatically activated when the vehicle is shifted into reverse and side inputs prompted by the turn signals. The APV4CAM is the perfect interface when multiple cameras are being installed on a vehicle.
Key Features:
- Allows up to four cameras to connect to a single display
- Four RCA camera inputs (front, rear, left and right)
- Single RCA output for connecting to compatible aftermarket AV headunit or display
- Connects directly to analogue turn signal circuit with flash eliminating signal buffer for uninterrupted side camera activation
- Priority override for reverse camera signal
- Provides reverse camera output trigger for aftermarket radios
Specifications:
- ADAPTER TYPE: MULTI CAMERA ADD ON INTERFACE
- VEHICLE PLUG: UNIVERSAL HARD WIRED
- CAMERA PLUG: RCA
- 12 PIN HARNESS DETAILS:
- YELLOW FEMALE RCAS: VIDEO INPUT 1, 2, 3, 4
- YELLOW MALE RCA: VIDEO OUTPUT
- PURPLE: REVERSE TRIGGER OUTPUT (+)
- 14 PIN HARNESS DETAILS:
- YELLOW: PERMANENT 12V
- BLACK: GROUND
- GREY: TRIGGER 1 (Negative)
- RED: TRIGGER 2 (Negative)
- WHITE: TRIGGER 3 (Negative)
- PINK: TRIGGER 4 (Negative)
- ORANGE: TRIGGER 1 (Positive)
- PURPLE: TRIGGER 2 (Positive)
- BLUE: TRIGGER 3 (Positive)
- GREEN: TRIGGER 4 (Positive)
- NOTES:
- Video Inputs / Outputs: The 4 inputs have priority in descending numerical order (eg. Input 2 will take priority over Input 3 when Input 2 is triggered). Input 1 has the highest priority and is therefore optimal for the connection of a reversing camera in many applications.
- Triggers: Positive Input triggers accept input voltages in the range of 2.5V to 12V. A voltage of less than 2.5V will fail to enable the channel. Negative Input triggers must be connected to ground to enable a channel. Do not connect both + and - trigger wires for a given channel. The reverse trigger output provides a 100mA 12V (Positive) trigger whilst any of the input triggers are activated. Upon deactivation of the last positive or negative trigger, the last video input source and the reverse trigger output will remain active for an additional 3 seconds.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them.
The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back.
I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to.
1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then.
They both needed a firm pillow that is not super soft, firm but not achy.
Finally found the perfect one.
